Editor Not Opening and Invalid API key[edit]

Running MediaWiki 1.16 In the latest version of firefox, 5.01, the editor wont open, and whenever I go to the page, I get a warning that I need a new API key. I registered for a new one and it still asks for a new API key. (I copy and pasted the key into LocalSettings.php so I don't understand how anything could have gone wrong) --Tdnotes 17:56, 9 August 2011 (UTC)Reply[reply]

GM2Wiki™ — russian alternative: Google Maps into any Wiki-projects without this Extension(s)[edit]

FIXED in the latest releases 9/29/09[edit]

UPDATE: I figured out how to fix it in media wiki 1.16.x + PHP5.3

Edit the file GoogleMaps.body.php

Change this line:

     function render16 ( $pContent, $pArgv, &$pParser ) {


     function render16 ( $pContent, $pArgv, $pParser ) {

It seems to be a PHP5.3 side effect. The error you get after upgrading to the newest stuff is:

Warning: Parameter 3 to GoogleMaps::render16() expected to be a reference, value given in ../includes/parser/Parser.php on line 3236 13:29, 29 September 2009 (UTC) - fixed by a random frustrated webmaster

This fix isn't working for me. I'm using MediaWiki 1.17 with php 5.3.6. Dsmithson 02:19, 12 July 2011 (UTC)Reply[reply]

How to ad Adsense to Extension[edit]

Any idea on how to add

Broken link to .kml file appears as <googlemapskml>[edit]

I use GoogleMaps-0.9.3 in combination with mediawiki-1.12.0 and PHP 5 and all works fine except for the .kml file export link in the "Special pages" section of the wiki, which appears including the "<" and ">" character entities, as follows:


I've seen the same appear on some other wiki's with GoogleMaps. Clicking the link will prompt the browser to download a plain text file named "kml" or ".kml", which contains the following line of text only:

No article found by the name of 

What is the purpose of the link and file and how can GoogleMaps be reconfigured to exclude it from the "Special pages" section? I'm not yet familiar with .kml files and their functionality, but I suspect they will not have a great deal of use on my particular wiki set up, and so it would be good to know how to remove the feature.

Thanks for any tips. ~ CampMaster, Sat Jun 21 13:53:06 CEST 2008

I'm encountering exactly the same phenomenon using exactly the same setup (GoogleMaps 0.9.3, MediaWiki 1.12, PHP 5). Any solution available yet?

Many thanks,

Hikey 10:39, 27 August 2008 (UTC)Reply[reply]

I just upgraded to MediaWiki version 1.13.3 and found that the broken link appears at the at the bottom of "Special Pages" of that version as well.

Is the link perhaps working as it should only on the latest development MediaWiki? Has anyone tested GoogleMaps on the SVN version? What exactly is the purpose of the link and is there a workaround? For example, can anyone post some quick tips below how to hide specific links in the Special:SpecialPages section of a current MediaWiki, either through CSS if possible(?) or by modifying a relevant MediaWiki configuration or program file?

Many thanks for any tips ~ CampMaster, -- 11:11, 13 January 2009 (UTC)Reply[reply]

Using Properties from Sematic Media Wiki as coordinates?[edit]

Hi, I use a database with semantic media wiki. Is it possible to use properties (geographic coordinates) as input for the map? The map should center around the specified coordinate given in the porperty and show a marker. Kai, 2007-10-31

Create a map link not visible?[edit]

Be aware that changing the user_options setting showtoolbar to 0 (hiding the toolbar) will also hide your Create a Map link!

You must have toolbar turned on to see the map link.

Center cordinates[edit]

it would be nice to have a dynamic center coordinate like those made with gpsvisualizer. -- 21:21, 26 April 2007 (UTC)Reply[reply]

Hopefully I'm barking at the right tree here; I made a quick-hack which zooms and centers automatically after loading all markers.
for 0.9.3 add the following bold lines (the other are fore reference) in file export/GoogleMapsJsExporter.php
at line 132, add:
        // add the marker to the map
        $this->mOutput .= " map.addOverlay(marker);";
        '''$this->mOutput .= " markerBounds.extend( marker.getLatLng() );"; // auto-center and zoom'''
at line 184, add:
      var map = new GMap2(document.getElementById("map{$numberOfMaps}"), { 'mapTypes': {$mapTypeArray} });
      '''var markerBounds = new GLatLngBounds( ); /* auto-center and zoom */'''
at line 239, add:
            $this->mOutput .= " document.getElementById('map{$numberOfMaps}').style.direction = 'rtl'; ";
        '''$this->mOutput .= " map.setZoom( map.getBoundsZoomLevel( markerBounds ) );"; // auto-center and zoom'''
        '''$this->mOutput .= " map.setCenter( markerBounds.getCenter( ) );"; // auto-center and zoom'''
        $this->mOutput .= '} addLoadEvent(makeMap' . $numberOfMaps . ');%%ENDJAVASCRIPT' .
You may want to leave out my auto-center and zoom comments also.
Note that this code will alway pan and zoom all of your maps: you might want to add an extra parameter for it.
Also note that this only pans and zooms for markers. GPolyline has a getBounds(), so you might want to write something that combines all bounds.

Fewer tiles[edit]

My site is mainly intended for smartphones so data volume is an issue e.g. small map of Berlin. Currently 9 tiles are always fetched, each at about 15 KB. Is it be possible to reduce this to just 4 tiles? Kimbooth 11:13, 3 March 2007 (UTC)Reply[reply]

Signing entries using tildes[edit]

Question: Is there any way to sign entries using four tildes ~~~~ so that every member on the wiki can add a point to a map and easily add their name and date to it? Thanks - MediaHound 03:14, 3 November 2006 (UTC)Reply[reply]

templates inside of Google map tags[edit]

This map is working great on our SingletrackWiki

Does anyone know if there is a way to make MediaWiki read template variables that are within extension code tags? such as:

<googlemap lat="{{{latitude}}}" lon="{{{longitude}}}" zoom="1" width="270" height="180" controls="small">{{{latitude}}},{{{longitude}}} {{{description}}}</googlemap>

This way, my template could be called by:

{{Googlemap | latitude = XX.XXXXXXX | longitude = -XXX.XXXXXXX | description = some landmark }}

Instead of the users having to put in all of those coordinates 3 times, they could put them in once and the template would automatically insert them into a "get directions" link, and into the google map extension tags, and create the map.

Any ideas on how this could be done? I know there have been various "mods" or "patches" for mediawiki that were created, but none of those seem to work with the current version.

You can make a template with variables, as you suggested above and use the syntax {{subst:googlemap|lat|lon|desc}}. This will produce the desired output, although it is unfortunately a one shot deal as it copies the text in the page that uses the template when it is saved. Changes to the template will therefore not be reflected on the end pages. This somewhat defeats the purpose, but can at least be used as a tool for users who don't want to mess around with the actual syntax. It still clutters the page, though. Less than ideal. --Charles
There's an open bug in MediaWiki about this (including a patch, if you're brave): bugzilla:2257 --Emiller 01:33, 8 January 2007 (UTC)Reply[reply]
I'm on mediawiki 1.10.1 and i patched parser.php but it still doesn't parse the maps code if i use it in a template. On the #wikimedia channel on freenode i was adviced: "There's a hook for it in the parser. It's a different hook than the normal extension hook. Extensions have to use the new hook if they want the new behaviour. Otherwise, it might break functionality. e.g. <math> uses {} itself", so apparently this could be fixed by just modifying googlemaps code and not waiting for a fix from mediawiki.
Now I tested it on 1.11.0, and it completely breaks the wiki after update. Needs to be disabled completely in order for the wiki to work. I'm surprised on one has yet addressed these problems.
It would be great to have this. -- 23:53, 4 January 2008 (UTC)Reply[reply]
Agreed! I wonder why it's not filed under new issues yet? Will it be in the next release? 11:12, 1 April 2008 (UTC)Reply[reply]
I'm actually looking for something similar, but not exact. I've got a template containing a number of locations (i.e. Template:Coordinates, which in turn includes other sub-templates, i.e. Template:Coordinates/Santa Monica), and I want to include that template in the googlemap code. <googlemap lat="..." long="...">{{Coordinates}}</googlemap>
Is this solution the same as the the one that will fix Mediawiki bug 2257? --NoTea 19:26, 26 January 2008 (UTC)Reply[reply]

Add a clickable sidebar?[edit]

Love the extension! I was wondering if there was any way that you could have a clickable sidebar that brings up the locations on the map and the corresponding info ballon. For example on my page Chester Wiki I have A for attractions, B for bars and R for restaurants. Is there anyway of adding the points into empty divs named sidebar1 sidebar 2 and sidebar3?

For example...This tutorial .

appreciate it might me a bit too much but any help would be great. Thanks

______________ I agree with this - the list of locations with corresponding balloons would be awesome - we could use it on as the campus map. Also search would be great - so that you can look for places within an area.

Installing stops MediaWiki from creating output[edit]

I installed the extension as per the basic three steps, but as soon as I complete the edit to LocalSettings, it completely stops the Wiki from operating (I just get an empty white page). Commenting out the two entries in LocalSettings gets the Wiki working again, what might I have done wrong? Thanks, Simon 16:38, 27 March 2007 (UTC)Reply[reply]

Hard to diagnose without more info. Look into your server's error log, or look at How to debug, it contains much more info which should help you diagnose the problem. --Tbleher 14:23, 29 March 2008 (UTC)Reply[reply]
I had this same problem, checked the logs as Tbleher suggested -- Turns out I'd unzipped the archive directories into the wiki root directory instead of into "extensions": so when php called the include, it couldn't find the file, and the page "build" failed. (eyeroll) Silly me. Thanks for the log suggestion, though: everything runs fine now.  :) Best! -- Diane Duane at youngwizards.com/ErrantryWiki -- 10:13, 26 April 2008 (UTC)Reply[reply]

Possible to change the size of the bubble?[edit]

I am wondering if there is possible to change the size of infowindow?

Yes, it's possible. I had the same problem, that the inside of the info window was too large for the box, resulting in very ugly rendering. This is most likely because of the problem highlighted here: http://econym.googlepages.com/css.htm
The workaround is to put the contents of the info window into a custom div with the right/expected dimensions. I used the following:
<div style="min-width: 120px; min-height: 120px;"> ... </div>

Zip Code Layer[edit]

I would like to add a zip code layer to my google map(s). I've seen this feature in the control area of the map on a few sites. Is this possible to add?

Labels on Markers and Area overlays[edit]

Hi, Aside from the basics, I'm not an expert of what is possible with Google Maps, but if I explain what I would like to do, perhaps someone could explain if it is posisble with this extension (or at all)? I would like to create a Google map where text labels hover alongside the markers. That is, the labels display without mousing over or click for the bubble. Is that possible?

Also, I'd like to create regional overlays - where as soon as the mouse enters a region of the map, the area changes colour and a clickable bubble becomes available for the region.

Basically I want to use a google Map as a powerful form of imagemap for site navigation purposes. I know I can put links into the bubbles, but I'm trying to make it as simple as possible for users. Having floating labels and being able to link out to demarcated regions would help a lot. Is this possible with GoogleMaps and this extension in particular?

Thanks Jon - www.peakbagging.co.nz 23:38, 28 May 2008 (UTC)Reply[reply]

26-dec-2009: I'm doing a Wiki devoted to the old churches around Bordeaux (where I live). The Google Maps extension works like a charm; however, like Jon, I'm interested in having a label next to the marker that shows the name of the church, as happens when I place a marker on a map at Google Earth. That way, people could use the marker to locate a particular church. See for example http://www.cle33.org/wiki/index.php?title=Auros_%28commune%29 where there are markers but no labels visible on the map to identify the churches. I know that when I hover the cursor over the marker, a bubble appears, but that is not obvious to the casual visitor. Any suggestions on how to address this issue?

(HALF-RESOLVED) Change link color in baloons?[edit]

KML Import Issues[edit]

Two things; I uploaded a kml to my wiki and specified it as the URL for the KML in the editor map and it spits out an "Unable to Load XML" error. Is it possible to store the KML file in a wiki? Secondly, I tried linking to a rather large kml file (about 17MB) and while the Google Map extension didn't spit out any errors - the information stored in the file never loads on the map. Is there size limit I should avoid?

display:none problem[edit]

This problem manifested itself when Google Maps extension was used along with Extension:Header Tabs - when inserted into the dive with style="display:none", map is freaking out since the div is zero size.

This can be fixed by setting size option of the map when GMap2 constructor is called. See Google Maps API docs: http://code.google.com/apis/maps/documentation/reference.html#GMap2

See email discussion about it (original problem was observed on Semantic Google Maps extension: http://groups.google.com/group/semacomm-dev/browse_thread/thread/4f8ff426a1b3f3b3

Is there a max data that could be included in this extension ?[edit]

Hi everybody !

I'm using this extension for my scouting wiki, since many month, but till my new update (0.9.2 then 0.9.3), some of my pages seem too heavy to be shown with the map.

For example: http://fr.scoutwiki.org/Cat%C3%A9gorie:Groupes_par_r%C3%A9gion_fran%C3%A7aise When you remove half of the data, the map is show... but else, there is a white space for the map, but nothing...

Trouble is: the limit wasn't there before (0.8). So where can I increase this limit ? I really need all these data.

Please help :-)

Undefined index errors[edit]

There were a bunch of these, taking up a lot of room on this page. I think I've put these to bed in 0.7.6. If you're still getting a warning, please post here. You can refer to the old errors in the Extension_talk:Google_Maps/Archive.

P.S. I am using your 0.7.7 beta version of the Google Maps Extension. --Malcolm Gin 22:16, 14 July 2007 (UTC)Reply[reply]
P.P.S. I think I found the problem, but I don't know PHP or Javascript enough to fix it. After looking at the PHP for the extension (I have no problems reading PHP, just not a lot of practice coding it), and looking at the output for my page, it looks like there are extra linefeeds in the function output for the caption. The continuation of the above code I indented, etc., is (I'll mark newlines/linefeeds as "\n":
<p>'; map.addOverlay(marker); marker = new GMarker(new GLatLng(42.7339, -73.197784), { 'icon':GME_DEFAULT_ICON }); marker.caption = '</p>\n
<p>'; map.addOverlay(marker); marker = new GMarker(new GLatLng(42.735413, -73.229713), { 'icon':GME_DEFAULT_ICON }); marker.caption = '</p>\n
<p>'; map.addOverlay(marker); map.addOverlay(...trucnated for pre tags...); GME_DEFAULT_ICON = G_DEFAULT_ICON; } else { document.getElementById("map1").innerHTML = "In order ... truncated ..."; } } addLoadEvent(makeMap1);\n
I assume, but don't know, that the linefeeds in the middle of the string literals are what's messing up the parsing of the map function and the display of the map. So, how to fix it? --Malcolm Gin 23:15, 14 July 2007 (UTC)Reply[reply]
P.P.P.S. Feel free to edit the long lines in the <pre> to fit the page. I'm submitting the data that way so the linefeed positions are clear. --Malcolm Gin 23:16, 14 July 2007 (UTC)Reply[reply]
P.P.P.P.S Looks like other people have had this issue too. I'll see if I can't haxxor your PHP for my own use with respect to this issue. Apparently the goal is to convert all linefeeds to '\n'. --Malcolm Gin 23:54, 14 July 2007 (UTC)Reply[reply]
Found the problem: I'm using $wgUseTidy = true; (which is not default behavior) in my LocalSettings.php to make ParserFunctions.php work. So unfortunately it looks to me like I have to either figure out if there's a subtle way to get this extension and ParserFunctions to work together, or I may have to choose between one or the other. --Malcolm Gin 00:26, 15 July 2007 (UTC)Reply[reply]
To clarify once again as I try to iron all this out, ParserFunctions generally works okay without $wgUseTidy enabled UNLESS one is using certain templates that generate tables dynamically based on parsed values. Since I'm doing that, that's why I've had to have $wgUseTidy enabled (without that, the HTML tags used - Wiki tables parse too late, I think - get HTTPencoded and display as <p>, et al., thus messing everything up). I'm by no means totally done looking into this conflict, but it seems more and more likely I'll have to choose between the two extensions. --Malcolm Gin 02:26, 15 July 2007 (UTC)Reply[reply]
I think this has been fixed in 0.8, please try it and report back. --Emiller 09:57, 6 August 2007 (UTC)Reply[reply]

OK, I think this problem is solved in 0.9. Try it out. --Emiller 00:31, 9 April 2008 (UTC)Reply[reply]
Is anyone still having this problem? I'm running 0.9.3 and it still occurs. It's definitely related to useTidy, because I'm okay when I set it to 'false,' but it's only been a problem since I upgraded my server's version of PHP. Is there an extension missing, or a safety feature enabled, that would cause the discrepancy between versions? Unfortunately I still need the tidy extension for now. Joezoo 12:56, 25 August 2008 (UTC)Reply[reply]
I'm having this problem as well. I'm running 0.9.3 with MW version 1.8.2. When useTidy is set to false, the map displays fine. When it's set to true, Tidy seems to stick some hard returns into the Javascript, and the map doesn't display. I have a test bed for my website and would be happy to provide Emiller with access to it for the purpose of debugging this. This is a really great extension, and I'd love to enable it on our site if we can get it working with Tidy. --Sheldon Rampton 04:32, 28 September 2008 (UTC)Reply[reply]
FTR, I am still having this issue with Version 0.9.4. I had to set $wgUseTidy = false; to get it to display on a page. Am using MediaWiki 1.13.2 and IE v6. -- PaulR 01:49 19-Feb-2009 (UTC)
I had this issue with Version 0.9.4 on MW 1.15.4. What I did to solve it was break up the HTML code that is used inside the Javascript blocks generated by this extension (for example '<div>' becomes '<'+'div'+'>'). This doesn't change the javascript semantics, but prevents Tidy from recognising these javascript strings as HTML in need of formatting. Here is what I changed in GoogleMapsJsExporter.php, starting at line 186:
                overlay.openInfoWindowHtml('<'+'div class="gmapinfowindow"'+'>'+
                    (overlay.title?('<b>'+overlay.title_link+'<'+'/b'+'><'+'br /'+'>'):'')+overlay.caption+'</'+'div'+'>',
                    { 'maxTitle': overlay.maxContent?overlay.title:undefined, 'maxContent': overlay.maxContent });

You're missing the '+'s in the first <b> on 2nd line. Anyway, this doesn't fix completely the problem, I still find the extension to be broken with the use of UseTidy, which is a pithy because navbox templates require this badly. FPL 18:59, 2 February 2013 (UTC)

When a marker is removed within a path[edit]

Wrong shadow for custom marker icons[edit]

I set the markers on my map to use some of the other icons Google has available (see here). Each of these has an accompanying shadow image. But in the GoogleMaps generated map, the shadow is that of the basic marker shape, which looks a bit funny - any ideas? thanks! --Zabwung 17:38, 7 January 2008 (UTC)Reply[reply]

Same problem for me. --Andrea

A workaround is to turn off the automatic shadows (shadow = "" in the googlemap tag), then put in two markers for each actual marker you want, one with the shadow icon as its icon, and one with the real one. List the shadow first so it appears behind the marker. This is mostly working for me with some issue of scaling of the shadow image. Alternatively if your custom icons are all the same shape, you can put the URL of the shadow icon in the shadow attribute above --Zabwung 21:20, 18 March 2009 (UTC)Reply[reply]

What version of MediaWiki? --Emiller 17:02, 29 January 2007 (UTC)Reply[reply]
I'm getting this problem as well. I'm running MediaWiki 1.9.3. --Lev 26 March 2007
Note that, after checking Extension:Google_Maps/Compatibility, I noticed that the GoogleMaps extension hasn't been listed as compatible with MediaWiki 1.9.3. (I've also had trouble with other tags rendering as "UNIQ....," so I'm not sure that this was a problem with the GoogleMaps extension.) I'm going to switch my site to the most recent legacy software (1.8.2?) and see if that works. --Lev 27 March 2007
Not sure if this counts as "Resolved." The problem is NOT with the GoogleMaps extension. It's a problem with the php.ini file on your host provider. WikiMedia's Bugzilla bug tracking system helped me find this MediaWiki UNIQ bug. After carrying out their recommendation, the GoogleMaps extension (as well as other tags like <nowiki>) works just fine. Note: I'm using MediaWiki stable 1.9.3. --Lev 28 March 2007

php error after installing v0.9.1[edit]

I'm using mediawiki 1.6.7 and php 4.4.2-1.1 and I've been using version 0.7 of the google maps extension for some time now. Replacing the GoogleMaps folder with the new files from 0.9.1 I get on calling any mediawiki page (and just that):

Parse error: syntax error, unexpected T_CONST, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in
/home/www/web111/html/w/extensions/GoogleMaps/GoogleMaps.body.php on line 25

If I counted correctly the line 25 is the first line with a command:

l.19--->class GoogleMaps {
l.25---> const PARSE_INCLUDES = 0;

Is the php version the problem? Can I update to version .9, though my webspace provider offers this old php version? Or might there be another problem. I did apply the "Colored paths"-changes to my mediawiki, and it worked with v.7. I hope someone might know better than I do, what this error message says. And thanks again for the great extension. And I can't wait to use the new kml features. -- JanCK14:18, 28 February 2008 (UTC)Reply[reply]

php4 problem[edit]

http://hubpages.com/hub/RootShell suggest, that the const keyword for defining class constants isn't available in php4. I don't know how to implement this line in that way that PARSE_INCLUDES becomes a class constant in php5 and a usual constant in php4. -- JanCK 01:51, 29 February 2008 (UTC)Reply[reply]

In 0.9.3 I get
Parse error: syntax error, unexpected T_STATIC, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/www/webxxx/html/w/extensions/GoogleMaps/export/GoogleMapsJsExporter.php on line 244
so I deleted the "static" keyword right before line 244 and in line 266. Then I got:
Parse error: syntax error, unexpected T_STATIC, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/www/webxxx/html/w/extensions/GoogleMaps/GoogleMaps.body.php on line 423
So I deleted the static in line 421. And in 553, 575, 593, 680, 771, 897, 909, 914, 928.
That worked. At least I got displayed my mediawiki start page. I'll now go on and check whether I can edit maps and export to kml. I don't speak php, so I'm not sure what I did by deleting the static keywords. I hope that's just a minor performance issue. Thanks again, for the great work. The extension is great, and I'll be real happy if kml export works for me now. -- JanCK 13:22, 9 April 2008 (UTC)Reply[reply]
Hm, doesn't work yet. Clicking on any edit link results in
Fatal error: Undefined class name 'self' in /home/www/webxxx/html/w/extensions/GoogleMaps/GoogleMaps.body.php on line 150
Oh, I see there are loads of "self"s and I don't know whether I can maybe change them to this->? Okay, I just read "self is the static analogy to $this, and parent:: is how you call a parent class's function, useful in constructors." at [1]. Just changing line 150 into
$o = $this->getMapSettings( $this->mTitle, $this->mMapDefaults );
allows me to display the edit-page. I can then use the map editor in the current firefox. On clicking submit, however, I get:
Fatal error: Undefined class name 'self' in /home/www/webxxx/html/w/extensions/GoogleMaps/GoogleMaps.body.php on line 397
The is not the next occurrence of self which is in line 316. But maybe that isn't called. So I did a replace all "self::" by "$this->" which replaced 15 further "self"s. Having done that I can display the pages without maps, but I can't display the pages with maps anymore. Those give me
Fatal error: Undefined class name 'self' in /home/www/webxxx/html/w/extensions/GoogleMaps/export/GoogleMapsJsExporter.php on line 161
To my surprise the error occurs at line 161 though there is a self in line 160. Here are lines 160 and 161:
$mapType = self::convertMapType($o['world'], $o['type']);
$mapTypeArray = self::getMapTypeArray($o['world']);
Those were the only two occurences of self in GoogleMapsJsExporter so I changed them to
$mapType = $this->convertMapType($o['world'], $o['type']);
$mapTypeArray = $this->getMapTypeArray($o['world']);
Now I can display pages without maps and pages with maps. AND the maps changed. Before the last change I this had the old options "map"/"sat"/"hybrid". Now I've got the new version "map"/"terrain"/"sat"(with/without labels). Maybe there was a caching problem, that allowed my to display the page with maps earlier on. I can edit the page with maps. I can start the map editor. Oh, and I just realize that even though I got the error page when clicking the submit button. The page got saved then. I can also now submit my edit without getting an error. Calling Special:Specialpages I get:
Fatal error: Call to a member function on a non-object in /home/www/webxxx/html/w/includes/SpecialPage.php on line 210
Line 210 in that file is:
if ( $page->isListed() ) {

foreach ( $wgSpecialPages as $name => $page ) {
if ( $page->isListed() ) {
$pages[$page->getRestriction()][$page->getName()] =& $wgSpecialPages[$name];
return $pages;
So I guess, know I have to understand how the Specialpage are hooked. .... and as my lunch is getting cold just now, I think I'll postpone that. -- JanCK 14:01, 9 April 2008 (UTC)Reply[reply]

But it didn't change much. It seems to me the class GoogleMapsKML isn't loaded though SpecialGoogleMapsKML.php is in the include path. hmmm? Dunno. -- JanCK 14:30, 9 April 2008 (UTC)Reply[reply]
Writing nonsense into SpecialGoogleMapsKML.php yields an error right away on loading any page of the wiki. So the file seems to be processed. -- JanCK 14:35, 9 April 2008 (UTC)Reply[reply]
Also changing the line to $wgSpecialPages['GoogleMapsKML'] = 'GoogleMapsKML';'' as I saw here didn't change anything. Manual:Special pages also says: It should be pointed out that the method used below will not work on PHP 4: it depends on "class autoloading" which was introduced with PHP 5. Special pages written in this style are therefore not necessarily compatible with MediaWiki prior to version 1.7.0: if using an earlier version of MediaWiki on a more-recent version of PHP, upgrade MediaWiki. But I hope that just refers to the line $wgAutoloadClasses['MyExtension'] = $dir . 'MyExtension_body.php'; which can be and is replaced by an include command. Am I right there? -- JanCK 11:30, 11 April 2008 (UTC)Reply[reply]
I fixed this php4 problem with specialpages through disabling the call to specialpages from /extensions/GoogleMaps/GoogleMaps.php in line 178 ff. just comment the line $wgSpecialPages['GoogleMapsKML'] = array('GoogleMapsKML', 'GoogleMapsKML'); out. i tried other solutions, but this works. -- 21:17, 27 February 2009 (UTC) good luck! frank.pfabigan@gmail.com, [2]Reply[reply]

Storing marker locations in the DB[edit]

I wanted to store map marker locations in the database rather than in wiki pages, and have hacked the extension to be able to fetch markers and display them--either all markers in a category, or just one marker by name. Would the diff/patch be of interest at all? Thinkling 22:36, 21 March 2007 (UTC)Reply[reply]

I have a site with a lot of differently centered maps, but would like to have the same markers/category of marker displayed on all maps, i think your patch may help O1ive 08:32, 14 May 2007 (UTC)Reply[reply]
I also have markers stored in a database and want to include them into a GoogleMap. Therefore I wrote a separate extension that includes the GoogleMap-extension described here and feeds it with coordinates and descriptions from my database. Using an old version of Mediawiki and the GoogleMap-extension version 0.5.5 everything worked fine. After upgrading my Mediawiki-installation to version 1.11.1 and using the GoogleMaps extension version 0.8.0 I'm not able to get the stuff working. Here's the code of my extension:
$wgExtensionFunctions[] = "mcmap";
function mcmap()
   global $wgParser;
   $wgParser->setHook( "mcmap", "renderMcmap" );
function renderMcmap ( $input, $argv, &$parser )
   global $wgParser, $wgUser, $wgTitle, $wgOut;
   $abfrage = "SELECT ... "; # my database query
   $ergebnis = mysql_query($abfrage);
   while ($data = mysql_fetch_assoc($ergebnis))
       $myoutput .= "..."; # generation my coordinates and descriptions
   global $wgGoogleMaps;
   return $wgGoogleMaps->render($myoutput, $argv, &$parser, &$parser);

The last two lines are highly doubtful, the return command causes an UNIQ/QINU error and non of the usual solutions helped me. Any ideas? --Dasaweb 11:19, 5 February 2008 (UTC)Reply[reply]

Safari can hang on long paths[edit]

I have not been able to isolate what the problem is exactly or where the limit is but I have a page with a 10-mile track with track points every 1/6th of a mile, I think. The page will load just fine on my Mac using Firefox but it causes Safari to hang indefinitely and the Finder says it is "Not Responding." This is the page causing the problem:


I wish I could identify what it is but I can edit out the path and add it back in pieces and the pieces show. I just don't know where, yet, it decides to balk. I do know this can basically work in Safari because the following page, displays properly:


Is it possible there is a limit to the number of points in a track that Safari can support? Could this be a weakness in the extension? Or could my data be malformed in some way?

OK, I started experimenting and found that it works up to 451 track points for this file, if I counted correctly -- I could be off by one. At 452, the previous version of the file, Safari still hangs:


I still don't know if this is just a size issue or in some sense due to the fact that much of the second half of the track overlaps the first half.

Have a look at this code. It's based on this Javascript. This PHP version is my work and can be used as is - note that it is loosely based on the original Javascript. Refer to copyright statement on original Javascript page.

Using the FCKeditor integration with MW 1.10.1[edit]

The normal MW editor is working fine but by default my users will use the FCKeditor. This editor shows no button for this google maps extension. I would like to know how I can either add the button into the FCKeditor or make some sort of link on the edit page which is outside of the editor area. (like I guess the older version used to use?)

Cache problem[edit]

I use Short URL for my MediaWiki installation, therefore I assigned two keys in $wgGoogleMapsKeys:

  1. MyIP/wiki/ (short URL, for /wiki/ArticleName)
  2. MyIP/w/ (real installed path, like /w/index.php?title=ArticleName)

Sometimes, the script said that the key is invalid in /wiki/Article which the key for [2] is used instead. I traced and tested the source and found it very weird that some variables are set differently. (For example, in GoogleMaps::commentJS(), the variable $this->mGoogleMapsOnThisPage is false in [1], but true in [2])

Finally, I resolved this problem by disabling some cache mechanism in MediaWiki. However, this is not a good in consideration of the server load. And after I enabled caching, the problem occured again. Is there any way to resolve this problem (and still using short URL)? Or do I need to provide more information?

Using this extension with the FCKeditor[edit]

I have to disable the FCKeditor in order to make the extension work because the "make a map" button will not show up anywhere on the edit page dialog with the FCKeditor. Can anyone help me or just give me some way of enabling this extension with the FCKeditor anyway? I'm not asking for full functionality with the FCKeditor or anything. Just a little text link above the editor window would be great! I just don't understand the complexities of the code well enough to get MW 1.10.1 to play with this extension and the FCKeditor integration at the same time!

I guess my problem really is: How can I instantiate the map editor somewhere else besides in the editor? (like maybe below or above it)

FCKeditor renders the <googlemap> tags just fine. I just need to let the user have an interface with which to edit the article since this is essential to the goal of my wiki site. (allowing each user a simple way to add a map to their article).

I am wondering if some of the code from the wiki + googlemaps extension can be utilized inside of the FCKeditor plug-in, possibly having them both installed side by side and adding a call to the parser inside of the google maps wiki extension. I don't know enough about js to do this. I am willing to help sponsor this feature. djoktiv@gmail.com

I tried this plugin - but I couldn't get it to work with the particular version of Fckeditor that is customised for mediawiki. version 2.5.1 ; Build 17566 MediaWiki+FCKeditor project. I'm running MW 1.12

This plugin may be assuming the standard version of Fckeditor
In the meantime you just have to add the tags manually, no big deal as most of my maps are simply pulling in KML files that I've created with GE. BTW, kmz files work as well :-)

Doesn't work on this wiki[edit]

I want to use it, but it doesn't work over here http://stad.wikia.com/wiki/ 19:13, 29 September 2007 (UTC)Reply[reply]

It works, but when the extension is enabled, I get a 4 lines of code at the top of the page[edit]

It won't let me copy & paste it, so here is the link to see what it is doing - [3]

Any thoughts?

The lines show "view.atdmt.com" - this is some sort adware - do a search on it in Google. I don't know how to remove it.

KML export problem 2[edit]

KML export working a lot better in 9.3. Couple of minor problems:

1) In general: a leading space in front of a co-ordinate is interpreted as marker syntax. So this will produce an unneeded marker.

-37.874202, 145.091622
 -37.874083, 145.093024
-37.873966, 145.094411

May make sense to trim whitespace from the beginning and end of each line?

2) A marker description such as this exported to KML file, which is designed to refer to an image on the wiki server, doesn't work as the URL is relative rather than absolute:

<![CDATA[<a href="/wiki/index.php/Image:IMG_4779_400_300.jpg" class="image" title="Image:IMG_4779_400_300.jpg">
<img alt="Image:IMG_4779_400_300.jpg" src="/wiki/images/6/6f/IMG_4779_400_300.jpg" width="400" height="300" border="0" /></a><br />]]>

3) Using IE7: When a user clicks on a KML download and uses the "Save" button, it all works fine. But the "Open" button doesn't work - Google Earth states the file cannot be found in the cited local temporary internet folder and correctly so - the file is not there. No idea why this happens. As expected it all works perfectly in Firefox. The server has the mime types all set correctly for KML

4) All marker titles now act as wiki page titles - so titles are in red indicating there is no wiki page of that name. Title will be in blue if there is a wiki page of that name. May be this was intended? - which may make sense. However, could a switch be put in to turn it off, which is my preferred presentation. A wiki page link can always be inserted in the description.

5) If you don't want the driving directions presented to you in the bubbles, then set up the BalloonStyle like so in the exported KML:

 <Style id="xyz">

Thanks once again.

KML export problem 3[edit]

I'm using MediaWiki: 1.10.1 with PHP: 5.2.5. The KML features all work except for export. The problem seems to be in the creation of the Special:GoogleMapsKML page. I get the following error when I click on a 'download KML' link:

  • "You have requested an invalid special page, a list of valid special pages may be found at special pages list."

I am using MediaWiki 1.14 and I am getting this same error.

GM plugin - mmmmm good stuff[edit]

  • I wanted to set the version of the Google API to 2.x, which as I understand it, always makes use of the latest GM API. However array element $o['version'] is set to a floating point number, whereas 2.x is a string. So when I set the override in LocalSettings.php I got a: "Parse error: syntax error, unexpected T_STRING". I would have thought the type casting would straightened things out but apparently not. I then tried to define $o['version'] as a string '2.85' but that didn't appear to work either. No errors but the override in LocalSettings.php didn't work. It is possible the browser's page cache might not have shown the update. Any thoughts on this?
This is a syntax error in your LocalSettings.php. --Emiller 08:32, 21 February 2008 (UTC)Reply[reply]
  • Would also like to see the help bubble size controlled, so it remains inside the map. The existing code:

Could be altered to:

openInfoWindowTabsHtml(overlay.tabs, {maxWidth:var_w, maxHeight:var_h, autoScroll:true} );
overlay.openInfoWindowHtml(overlay.caption, {maxWidth:var_w, maxHeight:var_h, autoScroll:true} );

Where var_w and var_h are built/derived from say:

var BUBBLE_SCALE = 0.5; 
var bubble_w = map.getSize().width  * BUBBLE_SCALE;
var bubble_h = map.getSize().height * BUBBLE_SCALE;

Or use GM's new maximise button code?

Or at least give the info bubble its own id for css, where htmlCode is the bubble text:

var divStyle = '<div class="gmapinfowindow">';
 htmlCode = divStyle + htmlCode + '</div>';

And css example:

   width: 400px;
   font-family: verdana, arial, helvetica, sans-serif;
   color: #000000;   /* of the text */;
   font-size: 0.8em;

Map doesn't load properly in IE[edit]

I just upgraded to 0.8 and i realise that the markers and shading on the map don't load immediately in IE, you have to click on Map/Hybrid/Satellite for them to show up, and then if you zoom in/out again the markers disappear. This works in Firefox and Safari just fine and it may have worked fine in IE before the upgrade, i'm not sure.

Anyone else noticed that, and hopefully know how to fix it? 00:04, 15 November 2007 (UTC)Reply[reply]

I am having the same problem with IE 6. I just installed this extension on a new Wiki. It was working fine yesterday and then today it was "broken" except my markers are showing just the map isn't showing. If it is set to Map or Satellite; the markers, controls, the overview, scale, Google/Map data copyright info, and the selectors show. But no streets or satellite pictures. If it is set to Hybrid the streets/neighborhood overlay shows plus the above-mentioned extras but not the satellite pictures. Also the zoom function does work even with no map/sat pics, you see the zoom "guide" appear and the sliding scale moves. If you switch from one type to another, then it all works fine until you reload the page. I checked out the Demo site and it worked fine with my browser so I believe it to be be server side. I tried disabling the cache and purging without success. I also went to the download site, installed 0.7.7 and that version worked fine. I also tried Firefox and it worked fine. -- 10:23, 4 December 2007 (UTC)Reply[reply]

kml import[edit]

version 9.2 with the following syntax I get the default lat long as defined in Localsettings.php. nothing from the kml file.


Grantiago 02:14, 17 March 2008 (UTC)Reply[reply]

To work around this, set the lat/lon in the <googlemap> tag:
<googlemap lat="..." lon="...">
--Emiller 19:40, 2 June 2008 (UTC)Reply[reply]
Picking up the lat long from the kml file needs to be on the feature list for .94 This work around also works for me, but it's painful to have to find the lat long, when that information is already embedded in the the KML that GE produces.

Dkruse 00:21, 4 June 2008 (UTC)Reply[reply]

The current design separates map properties (lat & lon, zoom level), which are tag attributes, from information about points, which are specified in the tag body. Your suggestion breaks down this division, and it's unclear to me what the map center should be when e.g. two KML files are specified. What would you think of a separate tag that can be used for specifying exactly one KML file? For example,
<googlemapxml height="200" width="300">http://...</googlemapxml>

Using Dynamic Page List (DPL) to auto-generate maps[edit]

Hi Evan,

on http://semeb.com/dpldemo/MapDemo you can find a map which shows "points of interest". The interesting thing is that the POIs on the map come from articles within that wiki; the articles only must use a simple template to state the coordinates and a text (or an image). That´s all. DPL collects those template calls and constructs a call of your googlemaps extension on the fly. It even generates a table with the POIs below the map.

I think this could be of some interest for others as well.

When creating this little application I found two minor problems with your code (regarding the use of uninitialized hasmap elements in php5). Bruno Marcuzzo sent you an email which contains the corrected version. Please check the changes I made and adopt them.

Algorithmix 14:49, 25 March 2008 (UTC)Reply[reply]

Reading about uninitialized hasmap elements in php5 I just wanted to ask whether code of Google Maps extension really needs the php5 features. Would it be difficult to get a version including the kml-features that works with php4? -- JanCK 03:11, 26 March 2008 (UTC)Reply[reply]

Importing Wikimapia KML[edit]

  • I imported Wkimapia KML file from wikimapia.org/ge.kml and saved properly initialized googlemap tag on my Wiki page, after saving the page the map is displayed properly but it doesn't reflect any of Wikimapia place marks. I have to click on the map to display them but the display was not nice, it was cluttered up by several yellow points and they were big enough to hide the places itself. EMiller can you pls try it yourself and better default the view to some Indian city as Wikimapia is quite famous here and each city have numerous place marks. It would be better if you put a small note on my Talk page on your reply. Thanks. Vjdchauhan 15:54, 18 April 2008 (UTC).Reply[reply]
    • These yellow points are actually present in the Wikimapia KML code and are intended for Google Earth users to click on them (after such a click, Wikimapia's complete title of the place is displayed in a popup). Fixing the issue you mentioned would most likely require parsing the whole Wikimapia KML output, throwing the defined points out. Such a parsing has to be server-side (because Google Maps API, used by Google Maps Extension, accepts only URLs of KML). — 11:04, 21 May 2008 (UTC)Reply[reply]

Please find out which mediawiki version and which php version you are using. I get the same error, because I use php4. For getting this version information delete include line for the google maps extension from LocalSettings.php and then go to Special:Version in your wiki to look for the versions. If you can miss out on the cool kml-features of the new version (which makes your data much better available for other mashups and google local search, etc.), you might be able to use an earlier version of the extension. I'm using 0.7.7 right now and it is working - though without and kml-support. -- JanCK 16:22, 22 April 2008 (UTC)Reply[reply]
Hm, maybe that's not the problem. I've just been to http://totenoc.org/wiki/Especial:Version and it said:
Produch Version
MediaWiki 1.12.0rc1
PHP 5.2.5 (cgi)
MySQL 4.0.27-standard-log
Dunno, what the problem is. Maybe you can solve this error by trying to delted the keyword "static" from that line. That helped me (though I couldn't make it work in the end: Even after deleting all keywords "static" and replaced all "self::" by "this->" I still couldn't make the SpecialGoogleMaps class to get loaded. But maybe you could see whether making the changes I made brings you as far as I got. Maybe we have a common problem that is not the php version.

But there is also http://totenoc.org/index.php and this yields the error. So I suppose your .php5 files are parses with php5 and .php files are parsed with php4. Try going to http://totenoc.org/index.php?Especial:Version or something like that. -- JanCK 16:45, 22 April 2008 (UTC) PS: I mean: Try going there after commenting out the google maps extension in LocalSettings.php. ... just to find out which version of the php processes .php files. -- JanCK 16:49, 22 April 2008 (UTC)Reply[reply]

Markers/Paths not appearing[edit]

mediawiki 1.12.0 and google maps extension 0.9.3

Installed the extension and seems to generally work fine. When using the editor, I can add markers and draw paths, and it gives me the markup to use. When I copy this markup into the desired page, Google Maps only loads the map and appropriate settings (e.g. the information inside the googlemap tag) but does not display any markers or paths.

Not all tags show on the map[edit]

http://totenoc.org/wiki/Esc%C3%B2la : it shows the map that can be seen at this address. The problem is that the tags are on two pages and that I can only see those from the first page. Any idea on how to show all? --Kokoyaya 22:12, 22 April 2008 (UTC)Reply[reply]

Could you explain this a little further? What do you mean by "tags on two pages"? And I'm not sure about the syntax here: Why are you using
as one of your inputfiles. I'd guess this lag the "&output=kml" option in order to get a kml file. Though I have to say the kml file you get then is not really what you'd maybe hope for. When I tested this all it gave me was a kml file with a link to the content. I had hoped to get a list of all points, but that seems more difficult. So this GoogleMapsExtension won't be able to parse the output, but maybe that isn't neccessary. Right now I'd assume that the extension just hands over the kml file to google maps for it to be evaluated there. Anyways, maybe I'm just not familiar with the syntax of this extension and links to google maps are allowed as input though the stuff you get back from the URL ist not kml but html with a map on it. Dunno. -- JanCK 23:02, 22 April 2008 (UTC)Reply[reply]
Tags on two pages = in the left column, tags show on two pages (see at the bottom) and the tags shown on the map are only the tags shown in the left columns (the second page can be seen at this page.

So you are telling me that using
as kml input gives you any results? I'm surprised about that. Are you sure? What do you mean by I tried without it? Have you tried without the additional kml-file? I suspect that non of your markers from the html-file are included in your wiki-map, and I would assume that you'd have to put the following URL as input, in order for it to work:

Hm, I'm sry, then I don't know. Maybe this is a bug. The following URL works for me:
So the link you tried works, when you tell google maps at maps.google.com to display it. I'm not sure why the google maps mediawiki extension doesn't display it. Maybe there is a parsing error for the complicated url? Or the kml file is too complicated. I'm not sure whether the extension looks into the kml file or whether he'll just hand it over to google. .... Hm, I just had a look at the kml file. It isn't as complicated as I thought. I get a file called "Escòlas e occitan.kml", when clicking the link. And it is of a very simple form. So I think it is more likely that a parsing error of the url causes the problem. Maybe you could try saving the above mentioned kml file to another location somewhere on your server. Then you can try including that. This could tell you whether the kml file is the problem or whether the url is. Surely, you'll lag the ability to update the file via the google maps interface during the test. So you might not want that for a final solution, but just for testing purposes ... -- JanCK 09:53, 23 April 2008 (UTC)Reply[reply]
I just wrote the following posting. You'll have to look at it in the editing mode as it describes the difference between "&" and "& a m p ;". However I didn't manage to stop the wiki from transforming the "& a m p ;" into an "&". So even the link that I speak about, which yields the error by google maps when copy and pasted from the "edit"-page of this page, is displayed here in a way that it works. However, this parsing by the wiki (I'm just guessing the wiki is doing it, as the links were changed too and I guess firefox wouldn't change links but just change the displayed strings.) won't apply to the below mentions javascript line, so the error keeps happening there. -- JanCK 10:31, 23 April 2008 (UTC)Reply[reply]
I don't understand this completely but for now I'd assume that it is a parsing error as I see that you put this url
into the googlemaps-tags. However the sourcecode says: (the line below isn't displayed as wanted. see above comment)
in the line (the line below isn't displayed as wanted. see above comment)
geoxml = new GGeoXml("http://maps.google.com/maps/ms?ie=UTF8&hl=fr&msa=0&msid=117602036879672436237.00044a8708e76338efb89&ll=43.938451,1.306686&spn=0.230904,0.711365&z=11&output=kml"); 
and the yields {errorText:"Es konnte keine Verbindung zum Server hergestellt werden."} as output for me. So the difference is that "&" gets parsed into "&" (<- = "& a m p ;" see above comment) and I guess it would work if that wouldn't happen. But maybe that's a security thing. Dunno. I guess the next step would be to look at the code that is parsing the URLs and thing about whether it's a security risk to not change & into &. But I guess you could just risk changing that for your wiki in the source code and hope that noone will take the time to exploit it. -- JanCK 10:22, 23 April 2008 (UTC)Reply[reply]

"Tab" problems with 0.9.3[edit]

We had GoogleMaps 0.7.7 working very nicely with our installation of MW 1.9.3, but switching over to GoogleMaps 0.9.3 has revealed some problems with tabs, both with "Version 0" syntax and "Version 0.9" syntax. Both problems can be seen on this page: http://isaacnewton.princeton.edu/9/index.php?title=Test/googlemap

Here is a description of the problems:

Version 0 Syntax[edit]

The first tab is fine, but the second tab opens up as a completely blank balloon.

Here is the googlemap text. It uses Template:wp defined as:

<googlemap lat="40.348654" lon="-74.659256" zoom=15 width=700 height=300 >
(b1) 40.348654, -74.659256

/University\ http://engineering.princeton.edu/data/images/footer_shield.jpg [http://www.princeton.edu Princeton University]{{wp|Princeton University}}

Version 0.9 Syntax[edit]

In this case, only one tab is generated.

Here again is the googlemap text:

<googlemap lat="40.348654" lon="-74.659256" zoom=15 width=700 height=300 version="0.9">
40.348654, -74.659256, Title

I believe the problem is that you have trailing spaces after the /\. I will change future versions to be more flexible. --Emiller 20:03, 2 June 2008 (UTC)Reply[reply]
FIXED as of 0.9.4. --Emiller 07:42, 28 January 2009 (UTC)Reply[reply]

GeoCoding support[edit]

Now that the google maps API supports GeoCoding [4] I'd love to be able to use real addresses instead of lat/lon

perhaps a format like 'adr: 101 Main Street, Cary, NC'

KML Import stopped working?[edit]

I might be missing something obvious here but I had KML imports working correctly on the following page:


pulling in the following URL:


However this appears to have just stopped working. I can't figure out what might be cusing this. If you view source the page it appears to be writing out all the correct javascript to get this working. Any ideas? I have tested the KML files in Google Earth and they are reading fine. Rodeoclash 01:35, 18 June 2008 (UTC)Reply[reply]

Further edit: You can see the KML file being loading into the standard google maps fine.


It appears that Google have changed the API. A temp fix is to change line 684 of the file GoogleMaps.body.php to

 			'api'         => '2.x',

I'll leave it up to Evan to implement the correct fix but if you're using the KML import function, this will get you up and running again.

Monobook changes[edit]

Special:Specialpages doesn't load[edit]

As I had problems with php4 and my host installed php5 now as standard I tried v.9.3 of the Google Maps Extension just now. I use: MediaWiki: 1.6.7 php 5.1.6-1 (cgi-fcgi)

Loading pages with maps and without seems fine. The editor works. I can go to pages like Special:Version. But I get an error, when going to Special:Specialpages.

Fatal error: Call to a member function isListed() on a non-object in /home/www/web780/html/w/includes/SpecialPage.php on line 210.

As listed in an earlier comment line 210 in that file is:

if ( $page->isListed() ) {

within the function:

function getPages() {
global $wgSpecialPages;
$pages = array(
=> array(),
'sysop' => array(),
'developer' => array()
foreach ( $wgSpecialPages as $name => $page ) {
if ( $page->isListed() ) {
$pages[$page->getRestriction()][$page->getName()] =& $wgSpecialPages[$name];
return $pages;

Calling the URL http://domain/wiki/Spezial:GoogleMapsKML I get

Fatal error: Call to a member function including() on a non-object in /home/www/web780/html/w/includes/SpecialPage.php on line 272

So there is a hook to this page, because I get a normal non-existence message for non-existing sites. Anyone else experienced that? -- JanCK 13:35, 30 June 2008 (UTC)Reply[reply]

I have the same problem that JanCK describes. I was successfully using GoogleMaps-0.8.0 but when I tried to upgrade to 0.9.3, I found everything worked except that my SpecialPages is broken. The error I get is the same as the one listed above except that it includes our local path to the wiki web space. Here are some other details about our installation (after rolling back to the working version of GoogleMaps):

I was able to get the features I wanted out of an upgrade (disable scroll zoom) and still maintain a working SpecialPages link by upgrading to 0.9.2 from 0.8.0. I expect the problem of the SpecialPages link will be resolved when I can upgrade our mediawiki to a more recent version than 1.5.6 and then I can get the most current version of googlemaps extension.-- 18:18, 30 December 2008 (UTC)Reply[reply]

The problem is still not solved in 0.9.4, Special Page still broken.

Double issue: Google key confusion, Firefox browser confusion (RESOLVED)[edit]

Just installed the latest GoogleMaps (0.9.3?), using MW 1.13. The edit box displays the Editor's Map icon, but when I click on it, two bad things happen: 1) a dialog box drops down and tells me "The Google Maps API key used on this web site was registered for a different web site. You can generate a new key for this web site at http://code.google.com/apis/maps/". I don't have any idea how this could happen; who are the two parties that have this conflicting information, and how can I fix this? i should mention that my key works elsewhere in my directory.

2) just below the edit icon bar the following text magically appears: "Unfortunately, your browser does not support the interactive map-making features. Try the latest version of Internet Explorer (Windows) or Firefox (Windows, Mac, and Linux)." Unfortunately, I am indeed using the latest version of Firefox (3.0.1) on the Mac. I've seen that this version of Firefox has some issues with GBrowserIsCompatible(); could that be the source of this problem?

Any advice would be greatly appreciated--Alan H 19:22, 29 August 2008 (UTC)Reply[reply]

Followup: I get the same "Unfortunately..." error message on a different computer using Firefox (also, the same API message, but that's to be expected).--Alan H 11:57, 30 August 2008 (UTC)Reply[reply]
Sigh...Both problems went away when I finally realized that the code that says something like "your API key goes here" was not actually code, it was an instruction! --Alan H 14:22, 15 October 2008 (UTC)Reply[reply]
Followup2: Got the first problem, serving 2 pages with GM included. While surfing as registered user none of the pages work. If I am not logged in, one of the pages works. Disabling referrers solves this problem, but is not practicable for our users. Any suggestions? -- Frederik 17:16, 25 September 2008 (UTC)
Followup3: When this happens, add ?action=purge to the end of your URL in the browser's address bar directly after index.php (or index.php5 depending on how your system is setup) and load the page. This seems to clear out whatever is interfering with the key. You only have to do this once until the problem occurs again. -- Sandy 20:18, 17 March 2009 (UTC)Reply[reply]
 Example: http://mywiki.org/index.php?action=purge

Link in the title is always in red (default edit mode)[edit]

Hi, I'm trying to use the title in the window when I clic on the marker. My problem is that it is always in red. The weird thing is it's really finding the page, but when I clic on it, I'm in edit mode. Do you know where to look to remove this "action=edit" in the title's URL? Or where to check when it's searching if the page exist or not, and add this action=edit after the url? In fact I cannot reproduce this on my local webserver on my computer, it's only not working on my production server (http://www.awaycity.com/wiki/Dublin/Swimming). If you can explain me how to test/debug or where to look, I would be very very grateful. Thanks in advance! Charles. PS:I'm using the 0.9.3, so could be great if you know the file, line where to look and after I will try and check what's going on.
RESOLVED: I checked on the source of the page and the link of the page had something wrong like some additional parameter: <a href=\"/wiki/index.php?title=Quality_Hotel&action=edit\"&awaycity_test_mw__session=05088ae126635ef414e1867c1446b389... etc After deleting my local cache, everything was allright. I think there is perhaps sth wrong with my vBulletin auth link.
by the way thank you for the extension: it's amazing :-)

Problems using Google Maps with a template[edit]

I'm trying to use the extension in a template, passing the latitude and longitude as variables to the extension. The code I'm using in the template is:


The page generated by the template displays the map, and appears to be substituting the latitude and longitude correctly:


But the map isn't centering on these coordinates - it's somewhere up in Wyoming (while these coordinates are in Colorado). Regardless of the coordinates that it substitutes, the map generated has the wrong center point (usually in Wyoming). The other parameters (zoom, width, etc.) seem to be working fine.

Can somebody help this newbie out?

--~~~~--04:39, 7 August 2008 (UTC)~ Ron

Additional info: I also tried using the syntax {{subst:googlemap|lat|lon|desc}} as described above, with no success (assuming I was implementing it correctly). Can anyone confirm whether this extension will actually work in a template? No need wasting more time if it won't.



Just wanted to laud you for a great extension! THANKS! -- töff 22:14, 11 September 2008 (UTC)Reply[reply]

Template syntax[edit]

First off, great extension - it's working wonderfully for the most part.

Quick question, maybe it's just my unfamiliarity with MediaWiki, but...

I'm using this in a template, it looks like:


This centers the map based on the latitude and longitude inputs.

The question: With the normal <googlemap></googlemap> syntax, the coordinates and descriptions between the tags become points on the map with labels. How do you recreate this with the template syntax?

Thanks in advance.

-- 19:49, 25 September 2008 (UTC)Reply[reply]

It is odd that this has not yet been responded to. If you have read Extension:Google_Maps/Syntax#Using_.3Cgooglemap.3E_in_a_template then you will be familiar with the {{#tag:googlemap|lat={{{1}}} lon={{{2}}}}} syntax that must be used when the <googlemap>..</googlemap> tags are to be used inside a template. That section explains the syntax for specifying attributes of the googlemap tag but it does not explain the syntax for specifying markers, paths or areas.

I wish to use a template to (i) standardize several attributes and (ii) insert a labeled marker at the same coordinates that are used for the map's initial center point. The first part is straight forward but the second part is pure guesswork at this stage. viz.

{{#tag:googlemap {{{1|-36.85}}},{{{2|174.793}}},{{{3|Auckland}}}

If you have successfully used template parameter(s) to pass data for defining markers, paths or areas then please share that syntax here.

Najevi 02:28, 4 January 2010 (UTC)Reply[reply]

Trial and error plus a little prompting from Help:Magic_words#Miscellaneous has paid off! The content of the tag is passed as an unnamed parameter. viz.
|version=0.9 |lat={{{1|-36.85}}} |lon={{{2|174.793}}} |doubleclick=recenter |overview=yes |scale=yes |scrollwheel=zoom |zoom=5<br/>

Google Maps with Basic Authentication[edit]

I've installed the Google Maps extension and added my API Key to LocalSettings.php but I'm not getting any maps and I am getting a Javascript error. I don't know if this is the reason but one possibility is that it's because the site uses basic authentication. I know the Google API site says it only works on sites that are "free to consumers." My site isn't a business and is "free" as in beer to its users. It's just not freely available to the world because some of the information is not public. It's basically a family site were my extended family shares stories and reminiscences and we'd rather it not be scooped up by the search engines. Yes, we're hoping to take advantage of Google without them being able to index the site and if that's unreasonable, then so be it.

On the other hand, the side doesn't have trade secrets or "account information" that would cost us if it got out so we didn't bother with SSL. It's just a simple MediaWiki site with basic authentication. Has anyone gotten this extension working with basic auth? When I turned off authentication it still failed so I'm not really sure that's the problem.

The Javascript error I'm getting is "unterminated string literal" on the line that ends:

overlay.maxContent) { overlay.openInfoWindowHtml('‹/p›

It appears that the next line has the rest of the string literal that starts on the end of that line, so there isn't an obvious problem there.

Any ideas?

Google Search Drawer stuck[edit]

  • First I want to thank the developer and whomever else has been involved in working on this extension, it's excellent and I've actually been able to teach a couple of other wiki users how to use it.
  • Second, I feel like an idiot, because this appears not to be a problem with the extension: I noticed today, some new behavior on my own site, that the Google Maps search text drawer at the bottom left of the default map is closed when entering "make a map" mode, and it won't open for me, in Safari, Firefox, or Camino- clicking on the left side of the closed Google Icon will open in a new tab the GoogleMaps site, but nothing happens when clicking on the magnifying glass or the right-pointing arrow. However, I notice that this behavior is not limited to my site- it happens on the demo site (willipedia) as well. This has got to be something retardedly simple. thanks in advance
  • Update: I still haven't been able to fix the above. I should note here however, that this has only started happening since I returned to Brasil from Ukraine. Could it have something to do with my IP?
  • Update as of 20 July: from outside Brasil, no problem with GoogleBar box appearing open when entering "make a map" mode. From Brasilian IPs, or at least the block I'm coming from in rural São Paulo state, no joy, GoogleBar won't open, as described above.

The only thing I can think of is that the Google API is disallowing Brazilian IPs for some reason, would like to confirm this with someone else in Brazil if possible. Link is http://www.colorist.org/wiki3/index.php/Sandbox --Robling 01:23, 21 July 2009 (UTC)Reply[reply]

Multiple API keys[edit]

Hi: I am a happy user of Google Maps extension on several of my portals. Now I tried to install version 0.9.4 (2009-01-27) on my wiki version 1.15.0 (PHP 5.2.9 MySQL 5.0.75) http://www.coastalzone.info, which comes with different languages and different URL, e.g. for the spanish version:

I got two keys for each language version and installed them according to your Multiple API keys section. This worked fine for a moment, but then I received the error message that "Google API Server rejects request". Next step was that I added "$wgEnableParserCache = false;" to LocalSettings.php.

Google Map Maker maps[edit]

First of all: I love this extension and it works fine.

E.g. http://www.google.com/mapmaker?hl=es&ll=11.236917,-74.192648&spn=0.041588,0.087204&z=14. Is there a way to include these kind of maps?

Customizing Editor's Map[edit]

We'd like to customize the Editor's Maps so that (1) no existing markers are add to the editor, and (2) the tags <googlemap ...> and </googlemap> (removing the latter seems easy) are not shown in the code. Very likely our maps will have many markers and the current behaviour could be unpractical -- what we want is to add markers, not to edit them. Any hint will be welcome. (Alternatively, the article content could be modified directly, since it will only contain the map and the categories.) -- 10:34, 18 September 2009 (UTC)Reply[reply]

Zoom to fit[edit]

Hi! How could the map automatically zoom and fit, showing all the markers? Something like that Thank You so much. enricostano AT autistici.org


I am running Wikimedia 1.15 and ver 0.9.4 of the GoogleMaps extension. Maps appear in the editor, but do not display when incorporated into pages. The problem is that the URLs generated have &amp; instead of &. I thought that this was supposed to be fixed in 0.9.4. Please take a look at: http://wikirun.com/Boston_Marathon (which has a big white space where the map should be.) Thank you in advance for your help. 04:33, 27 January 2010 (UTC)Reply[reply]

Fails on version 1.15.1[edit]

I have MW 1.15.1, and maps ext 0.9.4. the editor works, but when viewing the actual page i get nothing. no error either, just nothing. and "View Source" shows nothing too. i am using ParserFunctions, but i do NOT have $wgUseTidy = true; eg: when editing the page:

--> here is the map <--
<googlemap version="0.9" lat="54.572062" lon="-115.927734" zoom="4">
47.822991, -122.663086
--> map was before here <--

but when i save it looks like this:

--> here is the map <--

--> map was before here <-- 

and when i "view source"

<p>--> here is the map <--
</p><p>--> map was before here <--

Extension doesn't works on IE8[edit]


On my mediawiki installation (1.14), on loading map in IE8 pops up the next message:

1.15.1 and create map icon missing in edit tool bar[edit]

Running on an IIS box, monbook skin, new version 0.9.4 Works fine with old version of MW 1.13. Now, the map icon is missing from the toolbar. tried disabling all extensions, still doesn't show icon in edit mode. any ideas? --Phalseid 20:36, 18 March 2010 (UTC)Reply[reply]

When the icon did not show up in the toolbar of my mediawiki installation, the problem was that the coordinate floating point numbers in the generated javascript had a comma instead of a point as decimal separator due to a German locale. Putting the following line in LocalSettings.php fixed the problem:

 setLocale(LC_ALL, $wgShellLocale); # $wgShellLocale='en_US.utf8';

However, the extension should be fixed to not use locale dependent floating point number to string conversion. --Phispi 18:53, 28 November 2011 (UTC)Reply[reply]


What does this extension do that Extension:Maps does not do? Could that maybe be added to Maps, so we can obsolete this extension and combine all Maps functionality in one? siebrand 22:31, 17 April 2010 (UTC)Reply[reply]

This extension does add some GUI editing interface that generates map wikitext and also allows to display routes with multiple nodes. Having this adapted and moved over to Maps would be awesome, and I've been looking at doing that for quite a while. It's not a small amount of work to do though, and the author of this extension told me he won't do any active dev on it anymore. --Jeroen De Dauw 23:13, 17 April 2010 (UTC)Reply[reply]

#tag:googlemaps syntax not centering points correctly[edit]

I'm struggling with creating a template using google maps. Although everything appears to be substituting properly when using the syntax listed on the syntax page, the maps don't appear to be working properly - they aren't centering on the given lon and lat, but instead somewhere a number of degrees off.

Even outside the template, I can't get the #tag:googlemaps syntax to center properly - it's always off the given coordinates. So, for example, the following two pieces of code should be identical in effect, centering on Los Angeles

{{#tag:googlemap|lat=34.100434 lon=-118.243103}}
<googlemap version="0.9" lat="34.100434" lon="-118.243103">

But the first gives a map of a town in Massachusetts, while the second hits LA. Anyone have any idea why this is, or how to fix it? --Aekki99 18:59, 19 April 2010 (UTC)Reply[reply]

Extension not working properly for non-default directories[edit]

We use a centralized wiki installation and so all our personal extensions have to be in a different directory than "extensions."

How to use a set of custom markers?[edit]

After creating a set of custom markers by uploading an image in the very convenient web based Google Map Custom Marker Maker the resulting icon files are:

  • image.png (main foreground image)
  • shadow.png (shadow)
  • printImage.gif (for printing on some browsers)
  • mozPrintImage.gif (for printing on some browsers)
  • printShadow.gif (for printing on some browsers)
  • transparent.png (used to capture click events on IE)
  • imageMap (for capturing click-events in non-IE browsers)

The Google Map Custom Marker Maker returns the above files in a downloadable zip archive in addition to a code example that would normally be used when implementing a map using the Gmap API on a regular web page:

var myIcon = new GIcon();
myIcon.image = 'markers/image.png';
myIcon.printImage = 'markers/printImage.gif';
myIcon.mozPrintImage = 'markers/mozPrintImage.gif';
myIcon.iconSize = new GSize(19,22);
myIcon.shadow = 'markers/shadow.png';
myIcon.transparent = 'markers/transparent.png';
myIcon.shadowSize = new GSize(30,22);
myIcon.printShadow = 'markers/printShadow.gif';
myIcon.iconAnchor = new GPoint(10,22);
myIcon.infoWindowAnchor = new GPoint(10,0);
myIcon.imageMap = [12,2,16,3,17,4,17,5,17,6,16,7,15,8,15,9,15,10,15,11,15,12,15,13, etc..];

In the <googlemap> markup I can use define an alternate icon by:

<googlemap version="0.9" lat="..." lon="..." zoom="..." controls="large" icon="markers/image.png">

However, this alone does not necessarily account for an icon-matching shadow, unless the custom icon happens to have the same shape and size as the typical Google droplet marker.

Is it any way possible to use all custom images to include also the shadow and print image versions etc. as well as define a particular icon size?

Does a built-in syntax exist in Google Maps 0.9.4 for doing this directly in the <googlemap> wiki markup?

Map type error[edit]

For some reasonI can't use type="map". i.e. it doesn't display the map. Satellite view working just fine. map doesn't, also when clicking from within the map.

Maybe a bug for MediaWiki 1.17?[edit]

When rendering a map as simple as this (but something with markers):

<googlemap> 40.111689, -122.255859 </googlemap>

get warnings from ParserOptions.php::optionsHash() like so: Warning: in_array() [function.in-array]: Wrong datatype for second argument in ParserOptions.php

I fixed temporarily by checking the $forOptions array with an "is_array($forOptions)" but it seems that this extension is doing something wrong here.. not exactly sure what, any help would be great.

I did find this bug logged here, which is the same thing but figured my workaround plus more exposure here would be good: bugzilla:27543

I'm seeing this bug too on our Mediawiki installation. Once GoogleMaps extension is disabled, the error goes away. Could you be more specific on the steps you used to implement your workaround? --Tanuki85 07:00, 30 November 2011 (UTC)Reply[reply]

Inifinite loop when trying to fetch the content of the current page as a marker description[edit]

Let's say we have a page called "Foo" with the following wikitext:

<googlemap version="0.9" lat="54.613933" lon="-2.739973" zoom="14">54.606527, -2.74066, Foo</googlemap>

version="0.9" attribute will tell the code to include the content of "Foo" article as a marker description. googlemap tag will be parsed once more and cause include of "Foo" article. We end up in an infinite loop. --Macbre 14:28, 26 July 2011 (UTC)Reply[reply]

I'm seeing a similar problem (map worked in MW 1.17alpha a year ago, but is blank in last month's MW 1.19alpha, same wiki) http://mapt.be is 1.17alpha, http://www.mapt.be is 1.19alpha.

Switching to Extension:Maps may work in MW1.19 but does not support the same syntax (so not a viable option for an atlas-filled site like "mapt.be") and does not allow users to indicate a path on the map (it only allows points of interest, not full paths). I'd "upgraded" to MW 1.19 only to have to revert to 1.17alpha (ie: last year's MediaWiki code) on that one wiki just to keep this extension alive. --Carlb 18:15, 10 September 2011 (UTC)Reply[reply]

The reason why the current snapshot does not work is that "elseif" is used in JavaScript instead of "else if". This leads to an javascript error and that prevents the map to be shown. This bug was introduded in revision 90286: http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/GoogleMaps/export/GoogleMapsJsExporter.php?r1=90285&r2=90286&diff_format=u You just have to undo that commit, or at least the part of the commit that broke this extension.

Problems with search bar in editor's map[edit]

I'm finding that setting "geocoder" and "localsearch" in the $wgGoogleMapsDefaults variable to false is not disabling the search bar in the editor's map. Looking at EditorsMap.js, it seems to be using the showOnLoad property when creating the GMap2 object, and looking at Google's documentation, it appears this property of GGoogleBarOptions may no longer have any effect. I've had to comment out this.gmap.enableGoogleBar(); to stop the search bar appearing.

The search bar is a problem because I'm finding that when it's shown on the editors map, I can't save or preview any changes to the article I'm editing. Somehow the search box is confusing MediaWiki's handling of the form postback. When I click Save or Preview, instead I get taken to my wiki's search page, with a search for "search the map" (the default text in the search box on the editors map) displayed.
