Hi,
I am trying to do something similar.
I wrote a class inside a file in the main directory of my forum.
This is the code:

<?php 

// ######################### REQUIRE BACK-END ############################
require_once('./global.php');

	class codeigniter_bridge{
		
		function codeigniter_bridge(){
			
			$this->usernamager =& datamanager_init('User', $vbulletin);  
			
		}
		
		function prova(){
			
			return $foruminfo = fetch_foruminfo(1); 
		}
	}


?>

I receive this error:
Fatal error: Call to a member function do_db_fetch() on a non-object in /var/www/cyberludus.com/system/forum/includes/init.php on line 308

Where I do wrong?
Thank you
