The goal

The goal is the create a CMS that it can be is easily used my anyone, than in a classic CMS when we have an editor interface relay different than the site it is not an evidence where to start.

Than I think that wiki system resolved this problem but the problem, tor an association site we don't have edit button on all page especially the mane page. To solve that I create this extension (my first implementation: [lamargelle.ch La Margelle], my church ;-) ).

An other problem I have is to create an member area, to solve that the white list read is to restrictive than I introduce list of regular expressions (in future it can be replaced by name space but it create come technical problem).

History

• 28 04 2006 : add blacklist ($wgRegexpBlackGroupPermissions).

Features

• Create standard pages.
• Create member area.
• Create wiki area.

What

A Mediawiki extension used to manage dynamically the $wgGroupPermissions and the $wgDisabledActions.

Install

Ton install the extension :

• download this file as CMS-WIKI-like.php name
• copy this file in the extensions directory
• add include_once('extensions/CMS-WIKI-like.php'); after the $wgGroupPermissions.
• edit MediaWiki:Nosuchaction to Prohibited action.
• edit MediaWiki:Nosuchactiontext to You don't have access of this action be sure that you are login.
• in the LocalSettings.php replace $wgGroupPermissions by $wgRegexpGroupPermissions, the false value to array() and the true one by array('.*').
• replace the $wgRegexpWhitelistRead = array(...); by $wgRegexpGroupPermissions['*']['read'] = array(...);

Quick start

To use it you just edit or add attribute to $wgRegexpGroupPermissions[group][action or permission] = array of regexp to allow it, if other ignore it => all access.

A user manage access is viewmenu, is is used to view the menu. we can specify css classes to hide by using the $wgMenuClass' default value is '.editsection, #p-cactions, #p-tb' . then you need to add in the html header part of the skin :

<?php 
  global $wgHeaderAdds;
  if (isset($wgHeaderAdds)) {
    echo $wgHeaderAdds;
  }
?>

Example

A configuration example :

$wgGroupPermissions['*']['createaccount'] = false;
$wgGroupPermissions['user']['createaccount'] = false;
$wgGroupPermissions['user']['upload'] = true;
$wgGroupPermissions['sysop']['createaccount'] = true;

$wgRegexpGroupPermissions['*']['read'] = array('Main Page', 'MediaWiki:.*\.css', 'MediaWiki:.*\.js', 'Image:.*', 'Catégorie:.*', 'Special:Userlogin', 'Special:Search', 'Wiki:.*', 'Discuter:Wiki:.*');
$wgRegexpGroupPermissions['*']['viewmenu'] = array('Wiki:.*', 'Discuter:Wiki:.*');
$wgRegexpGroupPermissions['*']['edit'] = array('Wiki:.*', 'Discuter:Wiki:.*');
$wgRegexpGroupPermissions['*']['history'] = array();
$wgRegexpGroupPermissions['user']['read'] = array('.*');
$wgRegexpGroupPermissions['user']['viewmenu'] = array('.*');
$wgRegexpGroupPermissions['user']['edit'] = array('.*');
$wgRegexpGroupPermissions['user']['move'] = array('.*');
$wgRegexpGroupPermissions['user']['history'] = array('.*');

$wgAddToHideMenu = "<style type=\"text/css\">\r\n\/*<![CDATA[*\/\r\n.editor, .editsection, #p-cactions, #p-search, #p-tb { display:none; }\r\n\/*]]>*\/\r\n</style>\r\n";

include_once('extensions/CMS-Wiki-like.php');

//End of LocalSettings.php

The result is that we have a wiki part, Main Page, a restricted access part, only sysop can create accounts.

Other extensions I use

• Special page to work with the interwiki table
• Permissions
