Extension:Talkright

adds a talk permission independant from article edition

What can this extension do?

Talkright extension makes the editing of talk pages a distinct action from the editing of articles to create finer permissions, by adding the talk right.

Usage

The following example creates a group whose users can comment on articles but not edit their contents:

$wgGroupPermissions['commentators']['edit'] = false;
$wgGroupPermissions['commentators']['talk'] = true;

Installation

1. Copy the code below in a file named talkright.php in MediaWiki's extensions folder.

2. Add the following line in the LocalSettings.php file:

require_once("$IP/extensions/talkright.php");

3. Edit tab in talk page : a "view source" button is still existing on talk pages. To fix this problem, modify includes/SkinTemplate.php on line 672 changing :

 
" if ( $this->mTitle->quickUserCan( 'edit' ) && ( $this->mTitle->exists() || $this->mTitle->quickUserCan( 'create' ) ) ) {"
to
" if ( ($this->mTitle->quickUserCan( 'edit' ) || ($this->mTitle->isTalkPage() && $wgUser->isAllowed('talk'))) && ( $this->mTitle->exists() || $this->mTitle->quickUserCan( 'create' ) ) ) {"

4. Now you can use the talk right within the group user rights.

Fatal: mbstring.func_overload is active. Cannot install MediaWiki...

Installation of MediaWiki on shared host where you don't have php.ini access. Resolved.

Update 30.10.2009 : To resolve this problem on a Apache server, you've to edit /Applications/MAMP/conf/php5/php.ini files and search the lines : "mbstring.func_overload" ; the first line has the value "7" and the second "0", then change their value " to "off"; then save, restart the server and it works perfectly.
