MediWiki Integration

In the mean time a couple of years later, but I wanted this bridge between mediawiki and vbulletin too, and got it working, albeit with a few tweaks.

My setup:

* vBulletin 4.2.0 PL3
* Mediawiki 1.19.2
* PHP 5.3.17

I added a custom usergroup 'wiki' to vB. Members of this group (and admins and mods) are granted to log in to the wiki.

I used the code from the quoted extention above, but ran into 2 things:

1. Group selection was to 'tight' for me. I wanted to control the wiki access with an additional custom usergroup (so not the primary group)
2. I wanted to allow spaces, dashes and dots in usernames, since both Mediawiki as vB allow that currently

@group selection

In the functions userExists (and authenticate subsequently) I changed the query from

PHP Code:

$vb_find_user_query = "SELECT usergroupid FROM " . $this->vb_prefix . "user WHERE LOWER(username)=LOWER('" . $username . "')"; 


to

PHP Code:

$vb_find_user_query = "SELECT CONCAT_WS(',',usergroupid,membergroupids) as groups FROM " . $this->vb_prefix . "user WHERE LOWER(username)=LOWER('" . $username . "')"; 


With this, you can query both usergroup & membersgroups together.
Since you can have multiple id's in this 'group', the code to match it to the $this->allowed_usergroups needed a little tweaking.

I changed the bottom part of the same 2 functions from

PHP Code:

if (in_array($vb_userinfo['usergroupid'], $this->allowed_usergroups)) {
   return TRUE;
} 


to

PHP Code:

if (count(array_intersect($this->allowed_usergroups, explode(",",$vb_userinfo['groups']))) >= 1) {
   return TRUE;
} 


This way it doesn't matter if a member had one or more matching groups with the allowed_usergroups.

@allowed characters

Unfortunately I didn't succeed in modifying the search pattern to only accept alphanumeric or underscore characters in usernames. I did a dirty workaround to bypass the whole check.

I replaced

PHP Code:

(!preg_match($this->searchpattern, $username)) 


with

PHP Code:

(count_chars($username) > 0 ) 


in both functions.
If someone has a better solution I'd like to hear it. I'm not that kind of a guru at PHP
