UBBThreadsIntegration

Question

How can I use the user authentification of the UBBThreads forums ( http://www.ubbcentral.com/ubbthreads/(approve links) ) to control the access to my pmwiki installation?

Answer

This recipe enables all registered users on a UBBThreads forum to edit the wiki pages. The wiki pages in the Site group can only be edited by the users with the status administrator.

The recipe currently requires to edit the pmwiki.php file, as it wouldn't work when included only from the config.php file.

Installation instructions

1. create a file called ubbauth.php with this content:

 
 <?php
 //UBBThreads authentication 
 $pos = strpos($_SERVER['REQUEST_URI'], "?action=edit");
 if (is_numeric($pos)){
	require_once("/path/to/your/forum/includes/main.inc.php");
	$userob = new user;
	$user = $userob -> authenticate();
	if (!$user['U_Username']){
		$html = new html;
		$html->not_right("<br />You have to be registered and logged in
			at the Forums
			in order to edit this wiki document.<br /><br />
			1.) First  <a href='{$config['phpurl']}/login.php' target='_blank'>click here</a> 
			to open a new window where you can log in at the BB,
			(leave that window  open after you logged in)<br />
			2.) Then  <a href='{$_SERVER['REQUEST_URI']}'>click here</a> to edit the wiki 					page.");
			exit;
	}
}

Modify

/path/to/your/forum/includes/main.inc.php

to fit your forum.

Copy the file ubbauth.php to the pmwiki 'local' directory.

2. Add this to your config file:

$DefaultPasswords['edit'] = ($user['U_Username']) ? '' : '*';
$DefaultPasswords['admin'] = ($user['U_Status'] == 'Administrator') ? '' : '*';
$Author = $user['U_Username'];

3. Add this to the top of the pmwiki.php file, after <?php :

require_once('local/ubbauth.php');

4. Edit Site.EditForm and
replace:

 [=(:input e_author:)=] 

with:

 [={$Author}=]

Comments

I've used this integration sucessfully, altho with a couple of modifications. As I don't want just anyone to start editing our wiki, I've made ubbauth.php check wherther the user is a member of a group in Ubb. The changes made are the following:

Line8: $user = $userob -> authenticate("U_Groups"); //this makes authenticate lookup the U_Groups field in addition to the usual. Line9: if (!strstr($user['U_Groups'],"-7-")){ //This is checks if the user is a member of group 7.

In addition, I changed the author info in config.php for this:
$Author = ($user['U_Username']);

  Ah, right, this was an error on my part above, thanks, fixed.
