Mouseover
I have a lot of pins on some pages e.g. Museums in Berlin. To work out which is which, it would be good if just moving the mouse over the pin caused the info window to pop up. Is there an easy way to do that? Kimbooth 09:16, 3 March 2007 (UTC)
 * I'll have something like this in the next big version. --Emiller 19:18, 3 March 2007 (UTC)

What we will have in the next big version? What will be the new features? Lleoliveirabr 23:02, 3 March 2007 (UTC)

Fewer tiles
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)

Get directions?
Would it make any sense to have an easy link pointing to google maps to have directions to a certain point? --Jfbeaumont 17:06, 2 March 2007 (UTC)

Use mouse's wheel
It would be useful if when the mouse is over the map, the wheel was use to zoom in and out. Can we do that? --Jfbeaumont 17:06, 2 March 2007 (UTC)
 * I bet that's possible: http://adomas.org/javascript-mouse-wheel/. --Emiller 19:14, 3 March 2007 (UTC)

Can you position the map like you would an image?
for example can I get the text to wrap around an map? if so what code do I need? thanks for the help


 * Use some CSS, e.g.

&lt;div style="float: left;"&gt; ... &lt;/div&gt;

How do I change the pixel size of the paths?
I would like them to be quite a bit thinner, not so wide and transparent. --192.203.201.3 18:53, 6 February 2007 (UTC)


 * Right now the only way to do this is to modify the "initialize" function of EditorsPath in EditorsMap.js. Change "6" to a more acceptable value. --Emiller 03:20, 27 February 2007 (UTC)

where to change size and shadow size of custom markers?
Wow. Thanks for this really great extension. Easy to install, easy to use. Impressing results.

I have a question dealing with custom markers: when I use my own markers they will always zoom in (or zoom out) to the default marker size and shadow size. In my special case I like to use really small icons for the marker, just a few pixels, without shadow. Where do I change this for the marker icons in the script? --Wikisteph 10:37, 7 December 2006 (UTC)
 * Search for "new GIcon" in GoogleMaps.php and refer to http://www.google.com/apis/maps/documentation/reference.html#GIcon --Emiller 06:50, 18 January 2007 (UTC)

Hi, could someone make this a little bit more detailed for me? So I have to change the section from line 426 in GoogleMaps.php ? //<![CDATA[ var GME_SMALL_ICON; GME_SMALL_ICON = new GIcon; GME_SMALL_ICON.image = "http://labs.google.com/ridefinder/images/mm_20_yellow.png"; GME_SMALL_ICON.shadow = "http://labs.google.com/ridefinder/images/mm_20_shadow.png"; GME_SMALL_ICON.iconSize = new GSize(12, 20); GME_SMALL_ICON.shadowSize = new GSize(22, 20); GME_SMALL_ICON.iconAnchor = new GPoint(6, 20); GME_SMALL_ICON.infoWindowAnchor = new GPoint(5, 1); and uncomment the line with CDATA ? nothing changes for me if I change GSize, GPoint... Thank you --77.128.56.3 21:03, 28 January 2007 (UTC)


 * Actually, you need to change this line:

$output .= " GME_DEFAULT_ICON = new GIcon(G_DEFAULT_ICON, '".addslashes($o['icon'])."');";
 * Right after it, put something like

$output .= " GME_DEFAULT_ICON.iconAnchor = new GPoint(12, 10);";
 * --Emiller 03:20, 27 February 2007 (UTC)

Thank you for your answer! It worked for marker.png and firefox but not for IE. No more markers with IE. I had to change: function googleMaps_GetDefaults  and change the default "icon" =>  to s.th. i want to use. I didn't had to change anything in $output .= " GME_DEFAULT_ICON = new GIcon(G_DEFAULT_ICON, '".addslashes($o['icon'])."');"; Together it looks like this: if ($o['icon'] != 'http://www.google.com/mapfiles/marker.png') { $output .= " GME_DEFAULT_ICON = new GIcon(G_DEFAULT_ICON, '".addslashes($o['icon'])."');"; $output .= " GME_DEFAULT_ICON.iconSize = new GPoint(12, 10);"; $output .= " GME_DEFAULT_ICON.shadowSize = new GSize(22, 20);"; $output .= " GME_DEFAULT_ICON.iconAnchor = new GPoint(12, 10);"; } Is it possible to add even marker{label}.png. I tried with : if ($o['icons'] !=..........., but failed. Thank you

Signing entries using tildes
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)

Working with templates
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:

,

This way, my template could be called by:

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 lat . 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): http://bugzilla.wikimedia.org/show_bug.cgi?id=2257 --Emiller 01:33, 8 January 2007 (UTC)

Ok for Non Technical Users?
I'd like to use this on my site, but it looks technically beyond me. I barely get html, and know next to nothing about java or php. Is this something I can do, or should i get someone to help? And if I need to get help, how would I find someone qualified? Thank you for your assistance. --Natcolley 14:21, 26 May 2006 (UTC)


 * Hi Nat, if you can understand the installation instructions, you won't feel overwhelmed, I promise. --Emiller 02:43, 22 October 2006 (UTC)

remove 'make a map' link from edit page
Is it possible to remove the 'make a map' link from all edit pages. It seems to slow down loading of the edit page. I would just like to use the markup on whatever page I want the maps on. And maybe a link to the make a map page, which will help me get that markup, although this is not necessary. --Pdesai 19:45, 19 December 2006 (UTC)
 * You got it. Install version 0.7.5, and then add "$wgGoogleMapsDisableEditorsMap = true;" to your LocalSettings.php. --Emiller 06:18, 8 January 2007 (UTC)

Add a clickable sidebar?
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

Embedding a Googlemap in a table
Can this be done? I've tried pasting the googlemap-generated code inside a wiki table cell and the code shows up instead of the map. I haven't tried putting it in an HTML table cell, but I expect the result would be the same.
 * Nevermind. It works in an HTML table.
 * It works in a wiki table created with {| and |}, too. Thinkling 22:31, 21 March 2007 (UTC)

Search by Zip Code
Is there anyway to implement zip codes into these maps? I really want for articles on my site to have maps with markers on them, and then have people be able to search for things close to them by zipcode. is that possible? 75.111.46.8 22:12, 3 March 2007 (UTC)

Heyup
Love it. Pretty straight forward. Of course it would be nice to be able to get a new LAT/LON from messing around with the map, but for now I can paste them in from google links.

However, have you considered letting us specify the colour of the waymarker for the entries we make?

http://www.lundman.net/wiki/index.php/Tokyo

Thanks for your excellent code.

Ohh actually. This is unlikely, but I must admit it would be nice if you have a point, which leads to a page, to be able to have a return link "map" that takes you back (that's easy) and selects/centers the map point in question (harder) ...


 * Maybe you can figure out how to open links in a separate window? --Emiller 02:43, 22 October 2006 (UTC)

Not working well with cite.php
When the map is below pairs they do not appear on the page. When it's above them they appear. Page to look at is here. Feel free to experiment by copying it to the sandbox there.

Obviously the map at the top of the article is awful layout

0.7.5 Translation to French
I modified GoogleMapsMessages.php to add translation to French which I grabbed from Extension:Google Maps/Languages/FR.

"fr" => array(       'incompatible browser' => 'Pour voir la carte qui devrait être dans cette espace, utilisez un navigateur compatible.',        'no editor' => 'Malheureusement, votre navigateur ne supporte pas la création interactive de carte.

What can I do to fix it?

Antoine Sirianni 15:00, 17 February 2007 (UTC)

Well, I disabled notifications in php.ini file. I introduced a call to utf8_encode to manage accents.

'make map' => 'Créer une carte',

becomes

'make map' => utf8_encode('Créer une carte'),

In the case where there is some HTML text in the comments, I do not know if this modification fits. That is why I did not modify the whole array. It should also be valid for other languages.

--Antoine Sirianni 15:11, 24 February 2007 (UTC)


 * I think your text editor is speaking ISO-8859-1, which makes the call to utf8_encode necessary. Version 0.7.6 ships with the French translation in UTF-8, so you should just use that instead. --Emiller 04:15, 27 February 2007 (UTC)

I did it but still get pbs with translation. In defaultsettings, it says it speaks UTF-8:

/** We speak UTF-8 all the time now, unless some oddities happen */ $wgInputEncoding = 'UTF-8'; $wgOutputEncoding = 'UTF-8'; $wgEditEncoding  = '';

In localsettings, it says it speaks french:

$wgLanguageCode = "fr";

No ref to ISO-8859-1.

I get the same bug which I corrected with the same patch: utf8_encode('Créer ...

Undefined index errors
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.

Error:addLoadEvent is not defined
We have been using the Google Maps Extension 0.7.4 without problems for a while. I recently upgraded to MediaWiki 1.8.2 and installed the Semantic MediaWiki extension. Now in Firefox we are getting the error "Error:AddLoadEvent is not defined. And of course no map is drawn. Here is an example page http://www.archiplanet.org/wiki/109--115_Wood_Street

Here is a page showing the wiki tags we are using, the HTML source of a broken map page and the HTML source of that page back when it worked. It looks like the first couple sets of script tags are missing including the one where it calls Google Maps. I tried putting the map code on a page that doesn't use Semantic MediaWiki and the error still occured. I tried turning off SMW and the error still occured.

I have fixed it for now by commenting out both instances of "$wgGoogleMapsDidInsertEssentialJs = true;" in GoogleMaps.php. This causes it to load the initial script stuff for every map on the page, rather than only once as is intended, but for some reason it was not loading at all for me. It seems to work with multiple instances of that code in the browsers I have tested (Safari and Firefox).


 * The same is the case with SpamBlackList extension for mediawiki. Example on http://www.skipper2skipper.com. If blacklist extension is enabled, the GoogleMap javascript is not included in the page and no map is displayed. I have also disabled caching by commenting out $wgGoogleMapsDidInsertEssentialJs = true; (there are 2 instances) and all seems to be well. I guess it will need to be addressed at some stage as it does affect a few extensions, but the above fix should work in the short term. --Skipper 18:05, 6 January 2007 (UTC)

Problem with lines and RTL page in Hebrew
Hi

I'm having some issues with IE 6/7 and Hebrew MediaWiki 1.8.2. Did your changes so it finally works on IE 6/7, but when the line appears it is offset on the map. If you look at it with Firefox the line is in the correct place.

Editor doesn't seem to work on my site - RESOLVED
Just upgraded to 0.7.3 (on mediawiki 1.6.7). The "make new map" link shows up, however disappears when clicked. No editor shows up. Tested on XP in Firefox2 and IE6. Paths not enabled. See http://www.burkina.at/Satellitenkarte. --Helge 15:50, 25 October 2006 (UTC)
 * Hi Helge, the problem is that it expects {$wgScriptPath}/extensions/GoogleMaps/EditorsMap.js to lead to the EditorsMap.js file, but it appears you have some Rewrite rules that prevent this. Is your setup unusual somehow? I wonder how to fix this in all cases, because I bet people have a lot of unusual Rewrite set-ups. --Emiller 02:12, 26 October 2006 (UTC)
 * Aaah! Should have thought about that myself. Yes, my rewrite rules rewrite everything but a specified lot. So I now excluded the folder /extensions from the rewrite rules. My .htaccess file now reads like that:

RewriteEngine on

RewriteCond %{REQUEST_URI} !^/(stylesheets|images|skins) RewriteCond %{REQUEST_URI} !^/(redirect|texvc|index).php RewriteCond %{REQUEST_URI} !^/error/(40(1|3|4)|500).html RewriteCond %{REQUEST_URI} !^/favicon.ico RewriteCond %{REQUEST_URI} !^/robots.txt RewriteCond %{REQUEST_URI} !^/nowiki RewriteCond %{REQUEST_URI} !^/failed_auth.html$ RewriteCond %{REQUEST_URI} !^/stats RewriteCond %{REQUEST_URI} !^/extensions
 * 1) Don't rewrite requests for files in MediaWiki subdirectories,
 * 2) MediaWiki PHP files, HTTP error documents, favicon.ico, or robots.txt
 * 1) include these last two lines if you use the analog stats
 * 1) used to enable the GoogleMaps-extension (and all other extensions with similar issues):

RewriteRule ^(.*)$ index.php?title=$1 [QSA]
 * (Note: these .htaccess settings will only work if in conjuction with  in LocalSettings.php)

Template:Google Maps Extension Info
I think this template should only be used on the main page, because it creates to many entries in the category extension. Since all subpages have a link to the toppage, I do not see any problems here. --GunterS 19:19, 20 March 2007 (UTC)

Storing marker locations in the DB
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.

HELP...Connects points across map--ignores streets / markers not showing up in page
My googlemaps extension works except for the fact that when you connect points...it just draws a line right through the map to connect them--completely ignoring streets and such. Is there any way to fix this?

Also, I've noticed that the little place-marker balloons show up in edit mode but not when you preview/save the map...

I have Mediawiki 1.6.10 and Extension 0.7.7 and I'm currently using IE 6 and Firefox 1.5.0.9 (only because that's what users will be using) but it doesn't work on either browser.

I've re-traced all my steps from installation a few times and I still can't figure out what the problem is. Can someone help me on this? This is part of a project so a deadline is attached--Please help me! Thanks --Lolade 19:39, 25 March 2007 (UTC)


 * It's intentional that connecting points creates a straight line. If you want to have the line follow streets, just make multiple straight lines (you can do this just by clicking different spots on the map after clicking "start a path"). Points that show up as yellow markers will not show up in the final map. This is intentional; they're just there so you can change the shape of the path you draw while you're in edit mode. Hope this helps. --Emiller 05:53, 26 March 2007 (UTC)
