(OUTDATED) Searching uploaded documents

Is there any kind of extension that allows for searches within uploaded documents? It would be very useful. I believe Google Desktop could be integrated somehow...

(OUTDATED) Extension:Google Custom Search Engine

  • MediaWiki: 1.11.0
  • PHP: 5.1.4 (cgi-fcgi)
  • MySQL: 5.0.45-log
  • Database: Unknown, if you know how to figure it out please tell me.
  • URL: Red Orchestra Wiki

Alright so how do I get this extension to work? I made the page as said here, but any search returns to the main page, I actually wanted it to look like Wikipedia, where you can choose between Google search and MediaWiki search on the SpecialSearch.php.

(RESOLVED) Crosswiki checkuser problem

  • MediaWiki: 1.11
  • PHP:
  • MySQL:
  • URL:

I'm running MediaWiki 1.11 on a webhost, got Makesysop, Makebot and a few more extensions running. Checkuser works, but isn't actually doing a crosswiki log in the format:

  • FooBar got IPs for TestingUser on wiki1
  • FooBar got IPs for User2 on theotherwiki

Anyone know how to fix it?? —Whitsun 21:52, 19 February 2008 (UTC)

What is it doing? I'd need more info. Aaron 06:13, 2 March 2008 (UTC)
I couldn't install it via command-prompt on my webhost, so just copied the files from SVN to my website - and although it lets me do checkuser, it doesn't log properly. If you register an account I'll give you checkuser privileges so you can see what I mean. I can't get it to do a checkuser log that's cross-wiki like on Wikimedia's, e.g

User:Testuser@enwiki got IPs for Testuser1
User:Testuser2@fpwiki got users for
Thanks, -- 19:48, 3 March 2008 (UTC)

"doesn't log properly"? As in gives errors or as in a local-only log. As of recently, the log was redone to use the database, but for the moment (due to complexities with global DBs) it is local-only. This is true even on WMF sites now. Aaron 20:48, 3 March 2008 (UTC)
A bit of both actually. For some reason my host doesn't allow command-line stuff (well, not that I know of for, so it is hard. As for WMF sites, well, thanks for the note. So when a steward views the checkuser log on Meta or here for example, the log they see is only for this wiki?? -- 19:38, 6 March 2008 (UTC)

(RESOLVED) I Limiting edits by all users to approval only.

I want to be able to approve all edits by non sysop users before they go live. Is this possible?

_Matt (mattnewrock[AT]

You may want to check out Extension:FlaggedRevisions, which does mostly what you want in that only approved edits are shown by default but the latest is still accessible. If this is still not what you desire, consider getting a proper CMS instead of MediaWiki. --Skizzerz talk - contribs Tournesol.pngMediaWiki Support Team 03:03, 19 February 2008 (UTC)

(RESOLVED) CheckUser - cu_log empty, cu_changes not empty.

I have already installed this extension and found it not working. What is the problem? The cu_log is empty, so empty... And it is all that I have found out of my database and from the Special:CheckUser site, which tells me the same.

Of course, I've tried doing installation next time (deleting old thing and creating them using and Nothing happened.

And the second thing I've noticed: when I try to check smb's IP, I get the following warning:

Did you run the command-line install script? --Skizzerz talk - contribs Tournesol.pngMediaWiki Support Team 00:23, 21 February 2008 (UTC)
Yes. Now I've cleared the database from cu_* things once again and run install.php. Nothing new: I've changed one page, deleted another, tried if there is anything in cu_log - and there's nothing right now, as it was. And the same error, too. Peter de Sowaro 01:11, 21 February 2008 (UTC)
Should be fixed in r31448. Re-do the checkuser log table again. Aaron 06:13, 2 March 2008 (UTC)

(RESOLVED) Problems with Extension:Renameuser

  • MediaWiki: 1.11.0
  • PHP: 5.2.5 (cgi)
  • MySQL: 5.0.32-Debian_7etch1
  • URL: this

Hello! If I include require_once( "extensions/RenameUser/SpecialRenameuser.php" ); into my LocalSettings.php then on my MW the Spezial:Version will be shown as empty. Only the background and the header of the page is shown. If I comment the line in the LocalSettings.php (as in the moment is done) all works very well. The files for the extension I copied from there:

Hello. Try to escape non-standard characters in the 'author' field. Replace
'author' => 'Ævar Arnfjörð Bjarmason',
'author' => '&#198;var Arnfj&#246;r&#240; Bjarmason',

Thank you very much, it does it now. :-) As suggestion for extension-authors: perhaps that they use only standard characters. --Astrid 10:11, 22 February 2008 (UTC)

(RESOLVED) Some questions

Some questions:

  • I've seen that in Wikipedia there's a function (mainly used in templates) like this: {{#if:SOMETHING}}. I've tried to copy some lines on my wiki but that function doesn't work!

Is there an extension I have to install?

  • After I've installed the extension CharInsert.php when I try to access to Special:SpecialPages I receive this error:

Fatal error: Cannot redeclare setupspecialchars() (previously declared in /home/mhd-01/ in /home/mhd-01/ on line 48

If I remove the extension the problem is fixed..... why??

  • How do I edit the 404 error page that ask you if you want to create that article? There should be a MediaWiki:Newpage or something like this, I don't remember.......

Lorenzone92 20:47, 21 February 2008 (UTC)

It's MediaWiki:Noarticletext. A few others are MediaWiki:Noarticletextanon, MediaWiki:Badtitletext, MediaWiki:Noimage, but that seems to be the main one. -- 23:20, 21 February 2008 (UTC)
OK, thanks! And for the other questions? --Lorenzone92 21:56, 22 February 2008 (UTC)
Extension:ParserFunctions provides #if:SOMETHING among its various functions; the docs for CharInsert are here. --Carlb 03:31, 23 February 2008 (UTC)
OK, thanks!! And how can I export all my pages? In Special:Export I have to add them manually, how can I export/import all together (template/Mediawiki:xxx also)? --Lorenzone92 14:40, 24 February 2008 (UTC)

If you have access to the command line on your server:

  • php maintenance/dumpBackup.php exports every page in all namespaces
  • php maintenance/importDump.php imports them all together. --Carlb 01:04, 26 February 2008 (UTC)

(RESOLVED) Is it possible to have an article that pulls in content from another file at load time? (or at any time really.)

  • MediaWiki: 1.9.4
  • PHP: 5.1.6 (apache2handler)
  • MySQL: 5.0.27

Is there a way to have a wiki page that pulls its content from another file stored on my server? For example, I have a file on my server, already using MediaWiki markup, called "CHANGELIST" and whenever its updated, I'd like a specific wiki page to update its content based on whats in the "CHANGELIST" file.

I feel like this isn't something too difficult, and probably has been covered before, but my searching skills are just terrible and I can't find it.

Thanks in advance.

(RESOLVED) Question about Extension:KeepYourHandsToYourself and $wgNamespaceAliases

This looks like a pretty great extension, it's just what I need. But, if I have set$wgNamespaceAliases and changed the namespace name of "NS_USER", would it at all mess up the extension? Smaug 00:15, 25 February 2008 (UTC)

It should be fine; the extension is using !in_array($ns, array(NS_USER, NS_IMAGE)) to check for namespaces #4 (user) and #6 (image) by number, not by name, so the namespaces themselves may be named in any language without problems. --Carlb 01:14, 26 February 2008 (UTC)

(RESOLVED) PARSER extensions not working

  • MediaWiki: 1.11.1
  • PHP: 5.2.1 (apache2handler)
  • MySQL: 4.1.16-max
  • URL: INTRANET... Sic

I've got a problem with the image directory, where many images disappeared without explanation (I haven't found yet and I've checked the filesystem of the RAID1 device, reviewed all the logs from wiki, mysql and apache). The info associated to those "deleted" images is still in the database, though. Therefore, I decided to update the wiki (the "old" one was a 1.9.3) to the later stable build, say here 1.11.1. The database migration went smoothly.

I've upgraded the extensions and included some extra new ones. However, I cannot get three of them working: ParserFunctions, StringFunctions and ImageLink (but they appear to be OK at the Special:Version page). I've tried without success all the suggestions I've found on your help pages, the bugtracking search system, etc..., even google (web, groups, bizzcode, ...). I've also played to leave uncommented only one of them on the LocalSettings.php file. Having "display_errors" enabled, the wiki (and the corresponding apache logs with the variable disabled) produces the following warnings, one per "parsing" function:

Notice: Undefined index: if in *wiki_root_dir*/languages/Language.php on line 1145
Warning: array_slice() [function.array-slice]: The first argument should be an array in

Warning: Cannot modify header information - headers already sent by (output started at
   *wiki_root_dir*/languages/Language.php:1145) in *wiki_root_dir*/includes/WebResponse.php on line 10

The wiki then displays the corresponding page but all the templates containing the "parser" functions are embed "as is", without running the corresponding command. Any help would be greatly appreciated. Thanks in advance for your attention. Josep F Abril 20:22, 5 March 2008 (UTC)


Although I was looking forward a reply on this section, I've been trying many things. Finally, I've found what was going on. On the newer configuration file (LocalSettings.php), the initialization of the array $wgHooks is provided after the "Extensions" section. As I haven't found any counter indication on the installation manual or the embed comments; when migrating to the newer version of MediWiki, I put the requires to local installed extensions within that section (not at the end of the file), as follows:

 *  Extensions 

 * A list of callback functions which are called once MediaWiki is fully initialised
$wgExtensionFunctions = array();

/** ... Lines of code and comments
        from $wgExtensionFunctions
        to $wgExtensionCredits initialization
        ... ***
 * Where $type is 'specialpage', 'parserhook', or 'other'.
$wgExtensionCredits = array();


// to view all possible errors found in a page
$wgShowExceptionDetails = true;
error_reporting( E_ALL );
ini_set( "display_errors", true );

 * end extensions

By moving the following code, that initially I've found many lines after the extensions section,

 * Global list of hooks.
 * Add a hook by doing:
 *     $wgHooks['event_name'][] = $function;
 * or:
 *     $wgHooks['event_name'][] = array($function, $data);
 * or:
 *     $wgHooks['event_name'][] = array($object, 'method');
$wgHooks = array();

just after the $wgExtensionCredits = array(); line, everything started to work: no errors on pages, no errors on logs, all parser extensions being replaced...

I hope this will help anybody else having problems with the parser extensions. Cheers... Josep F. Abril 19:15, 11 March 2008 (UTC)

(RESOLVED) Blank Page after Executing Hook

Hello, I've attached a function to the ArticleSaveComplete hook. The function completes successfully, but the user is then presented with a blank page rather than being directed back to the article page like they were before. Do I have to return a special value or do something special in order to redirect the user to the article? Or does this mean that I've done something wrong with the called function? 02:30, 8 March 2008 (UTC)

Nevermind, I figured it out. One of my local variables had the same name as a variable passed by the hook, so it was causing an error when I changed it. 17:58, 8 March 2008 (UTC)

(OUTDATED) onclick event overwritten by checkboxClickHandler in my extension form

I have created an extension with a form in it. The form has a checkbox with an onclick event set to call a javascript function. The function is never called. I have traced the problem to the wikibits.js file where all input tags of type checkbox have the onclick event set to checkboxClickHandler. Is there anyway to turn this off, to not have my onclick overwritten? This site is on my local machine and is not available to the outside. I do not have the same problem with our 1.8.x installation of mediawiki.

I added the following to wikibits.js to the addCheckboxClickHandlers function:

   if ( !cb.type || cb.type.toLowerCase() != 'checkbox' )
 + if ( cb.onclick )
 +         continue;
   var end = checkboxes.length;

And the problem goes away, but not sure if this breaks anything else. 18:20, 12 March 2008 (UTC)

(RESOLVED) Smilies Extension

Is there a smilies extension that allows for replacement of certain words with images? I would assume a bot function would be necessary for this. -PatPeter, Tournesol.pngMediaWiki Support Team 00:53, 26 March 2008 (UTC)

You certainly could use a bot for this, but it would probably be a lot more efficient to work with the parser: Extension:Emoticons does this (though it may need updating). —Emufarmers(T|C) 03:01, 26 March 2008 (UTC)

Just from a quick examination of the code, I think I see a simple hack. Replace
&& $parser->mTitle->mNamespace !== 8
&& $parser->mTitle->mNamespace == 1
1 is the main talk namespace; you can replace it with whichever namespace you want to enable smilies on (and you can have it apply to more than one namespace if you want). —Emufarmers(T|C) 03:32, 27 March 2008 (UTC)

(RESOLVED) Installing LaTex

I have been trying to install LaTeX on my MediaWiki site, but I have had some difficulty since I am on a shared web server and cannot use SSH or run command lines. How can I get LaTeX and all of the necessary executables to work given these limitations, if possible? — 21:39, 9 April 2008 (UTC)

If you want to install the Extension:Wiki2LaTeX you need to have LaTeX installed before. This can only be done by your administrator. --Flominator 07:03, 10 April 2008 (UTC)

(OUTDATED) Protect a namespace, NameSpacePermissions

I like to create a Namespace which only registered users can access and edit. I tried serveral ways, but nothing worked ;) The last one was to install "NameSpacePermissions" as an extension. I added this code to my Localsettings.conf :

$wgExtraNamespaces = array(100 => "intern", 101 => "Intern_Talk" );

$wgNonincludableNamespaces[] = NS_INTERN;



Does anybody have an idea how to

  • disable read-access for anonymous to "intern"?
  • enable read+write access for all registered users for "intern" ?

With the settings above, it looks like anonymous users can not edit them but still view them. I know these settings are working in another mediawiki-installation (1.11.) so it might have something to do with the version 1.12.0 ?

1) Maybe you should post SocialProfile-related questions to Extension talk:SocialProfile rather than here, I know that I at least watch that page actively, unlike the support desk pages. :)
2) Are you using the latest version from SVN? If not, please upgrade to it. The SourceForge version at least causes problems like the one you mentioned, it's very buggy and most likely compatible only with MediaWiki 1.10. --Sayuri 18:05, 10 May 2008 (UTC)

If you got your realname stored somewhere within your LDAP directory you should be able to change cn to the field where the realname is stored, see here. --Flominator 06:07, 15 April 2008 (UTC)

Hi Flominator and thanks for the answer but I will login with my Number but when I will make a sign I will see the Real Name instead of the Login Name... Means, Login with number but when you make the --~~~~ then I will see the RealName. -- 06:18, 19 April 2008 (UTC)

Oh! I don't know how exactly to do it, but you should try to find a way to put the realname after "nickname=" in the field user_options of the user table in your database. --Flominator 09:12, 3 May 2008 (UTC)

(RESOLVED) Prevent MediaWiki from putting HTML tags in my tag extensions

  • MediaWiki: 1.12.0
  • PHP: 5.2.5 (apache2handler)
  • MySQL: 5.0.45-max-log

How can I prevent MediaWiki from putting HTML tags like paragraph and definition tags in my own tag extensions? You know, the auto linebreak and indention stuff, e.g. when you start the line with a colon.

More concrete, I enabled TeX using this technique, but MediaWiki dealt with linebreaks before the code was transformed into the formula image. So, a TeX expression like

  \frac{\Delta y}{\Delta x} &= \frac{f(x_0+\Delta x) - f(x_0)}{\Delta x}\\
                            &= \frac{\bigl((x_0+\Delta x)^2 - 3(x_0+\Delta x) + 2\bigr) - (x_0^2 - 3x_0 + 2)}{\Delta x}\\
                            &= \frac{x_0^2 + 2x_0\Delta x + \Delta x^2 - 3x_0 - 3\Delta x + 2 - x_0^2 + 3x_0 - 2}{\Delta x}\\
                            &= \frac{2x_0\Delta x + \Delta x^2 - 3\Delta x}{\Delta x}\\
                            &= 2x_0 + \Delta x - 3.

would end up like this.

When I saw this I wrote an own tag extension for math tags, but the output was all the same. This is the extension code:

$wgExtensionFunctions[] = 'efMyTex';
function efMyTex() {
    global $wgParser;
    $wgParser->setHook( 'mathx', 'efMyTexRender' ); // not sure if I can overwrite the built-in math tag here
function efMyTexRender( $input, $args, $parser ) {
    return '<img class="tex" src="' . $input . '" alt="LaTex: ' . $input . '">';

I didn't find the slightest hint concerning my problem in the manual and nobody was able to help me on the IRC channel, so I'll be more than glad if someone here could direct me in the right direction. 15:10, 27 April 2008 (UTC)

Nevermind. A simple rawurlencode() in the output HTML did the job. I mixed up MediaWiki's parsing order. -- 14:48, 28 April 2008 (UTC) (formerly

(OUTDATED) dumpHTML extensions - cscript error

  • MediaWiki: 1.12.0
  • PHP: 5.2.1
  • MySQL: 5.037
  • URL: [5]

Hallo, We are using MediaWiki 1.12.0 (Windows XP, PHP 5.2.1, MySQL 5.037). When we try to make a simple HTML-dump of our MediaWiki installation, we get this error-message:

"Der Befehl 'cscript' ist entweder falsch geschrieben oder konnte nicht gefunden werden." (Command 'cscript' is either written wrong or could not be found).

The offline-version of our Wiki seems to be fine - but we can neither use the left-side links (bar) nor links to pages, which use special characters (Umlaute). Maybe this might be of interest: Our online-version uses utf-8, so we had to set in LocalSettings.php

"# Experimental charset support for MySQL 4.1/5.0.

I've installed MediaWiki 1.11.0 and was trying to implement a security extention to prevent a user from viewing restricted pages. I tried using the PageSecurity, but when I implement the site won't display.

Is there a way to restrict all pages put into a certain namespace? What's the best method for locking down senitive pages?


Melissa — 19:25, 30 April 2008 (UTC)

For an entire namespace, perhaps $wgNamespaceProtection will help you. For an individual page, you can log in as an administrator or user with enough rights and protect the page using the "protect" action tab. Smaug Tournesol.png 19:33, 30 April 2008 (UTC)

Does this mean that the setting below would keep everyone but 'root' from editing the mentioned NS?

$wgGroupPermissions['root']['editroot'] = true;

$wgNamespaceProtection[NS_MAIN]     = $wgNamespaceProtection[NS_USER]  =
$wgNamespaceProtection[NS_PROJECT]  = $wgNamespaceProtection[NS_IMAGE] =
$wgNamespaceProtection[NS_TEMPLATE] = $wgNamespaceProtection[NS_HELP]  =
$wgNamespaceProtection[NS_CATEGORY] = array( 'editroot' );

I'm reading up on the $wgNamespaceProtection, it should work.... but when you connect to the Wiki how to you save pages to a set NS? Thx, Melissa

Seems like it should work. To edit pages in those namespaces then, as you have written the code, you would have to log in as a user in the "root" group. Try it out. Smaug Tournesol.png 18:27, 1 May 2008 (UTC)
Are you saying that I much create custom pages to utilize additional namespaces? I'm new to MediaWiki and trying to understand how this works. I've assigned the user to the group/namespace. Im trying to locate the data in the database to show which namespace is being used. Melissa

(RESOLVED) Batch Enrolling Of Users

(RESOLVED) Parser Functions if

I have the Parser Functions extension installed on my wiki, and I have a template I want to use an if statement on, if the template is being displayed on a page in the Image namespace, I want it to have some specific text; if the template is being displayed on a page in the Media namespace, I want it to have some diffrent text; or if the template is being displayed on a page in neither of those namespaces, I want it to have some other text. Now I would assume I would have to do some nested if statement like

{{ #if: <condition string=image ns?> | <code if true=image text> | {{ #if: <condition string=media ns?> | <code if true=media text> | <code if false=generic text> }}}}

Now the big question, assumming the logic there is right, what would the condition statement be to check if its being displayed in the image namespace or the media namespace?-- 14:59, 4 May 2008 (UTC)

Well I did a little googling and i might have found the answer:
{{#if:{{ns:image}}|Image Text|{{#if:{{ns:media}}|Media Text|Generic Text}}}}- 15:06, 4 May 2008 (UTC)
Well small issue, I tested it on my wiki, when you view the template, it's in the template ns so it should be displaying the generic text, but it's displaying the image text instead.- 15:08, 4 May 2008 (UTC)
Well I figured it out afterall all I need is:
{{#ifeq:{{NAMESPACE}}|{{ns:image}}|Image Text|{{#ifeq:{{NAMESPACE}}|{{ns:media}}|Media Text|Generic Text}}}}-- 15:22, 4 May 2008 (UTC)

(OUTDATED) Working in a symlinked tree

  • MediaWiki: 1.12.0
  • PHP: 5.2.4-2ubuntu5 (apache2handler)
  • MySQL: 5.0.51a-3ubuntu5
  • URL: private (RFC 1918)

My installation structure is something like this (names changed for simplicity):

  • ~/source - the original MediaWiki source
  • ~/base - created with lndir(1), symlinks to the source to make upgrades easier
  • ~/web/wikin - the live installations

Any source hacks are done by copying files into base, also storing diffs in there. Extensions are also stored in base. Each wiki setup holds its own LocalSettings.php and its own images (for now). With this model, upgrading has previously proved to be quick and easy, with little fuss. (I can write some more about this is people are interested)

While trying to install Extension:CheckUser to one of the wikis, I get the following message:

A copy of your installation's LocalSettings.php
must exist and be readable in the source directory.

Presumably, this means it's looking in the source rather than the live install for it. Is there any workaround to manually dropping each LocalSettings.php into the root of my source tree, such as overriding the lookup paths it uses? t.i.a. 11:50, 14 May 2008 (UTC)

(RESOLVED) Removing link markers in print; request for span element

I've run into a problem in Cite.i18n.php. I've been doing some experiments to create print-quality PDF documents from Wikipedia. In the current markup in the generated list of references, visible markers (^, a, b etc.) are added to allow users to click their way back to the source of the reference. In print, however, these markers should not be visible. Given the current markup, it's impossible to remove the markers by way of CSS as there is no wrapper element around them. I therefore suggest adding a "span" element with a class name of "backlink" or something so that one could remove these markers when printing the document.

Can someone point me in the right direction as to where my error is, or possibly another log that could give me more information? - 17:54, 29 July 2008 (UTC)Chet

(OUTDATED) problem with #tag: in a 1.11 to 1.12 upgrade

i was using the #tag parserFunction in 1.11 with attributes on the same line, but the content spanning multiple lines....


in 1.12, where #tag is built-in, the 'mytag' extension i wrote only receives 'someattr' as its input.

if i omit 'someattr', however, the 'mytag' extension does see all of the content lines.

similarly, i have another tag which is invoked as....


in which the tag only receives 'someattr=value' -- but as the "content" of the tag, not one of its attributes.

in both cases, the presence of an attribute seems to cause things to fail, with the attribute becoming the content and the content being ignored.

There may be a bug in CoreParserFunctions.php, line 235 of the mediawiki-1.12.0 bundles

		if ( count( $args ) ) {
			$inner = $frame->expand( array_pop( $args ) );
		} else {
			$inner = null;

I substituted array_pop for array_shift, to retrieve the last (not first) item; this now faithfully reproduces the behavior of the #tag extension in 1.11.

i would assume we're interested in "backward-compatibility" for the #tag extension; otherwise, i have lots of editing to do in my documents!!!
