Since it is in the class you will probably have to do it this way:

PHP Code:


		
			
$this->registry->db

instead of

PHP Code:


		
			
$vbulletin->db

This deals with the foundations of Object Oriented Programming.

Since postbit_display_complete exists in a class, the $vbulletin object must be aggregated to that class.

vBulletin programming standards aggregates the vBulletin object to $registry.

PHP Code:


		
			
$this->registry &= $vbulletin;

All class attributes can be accessed within the class with

PHP Code:


		
			
$this

(Outside the class $this will be changed to the actual object name: ie: $vbulletin)

So you access the $vbulletin object inside the class as:

PHP Code:


		
			
$this->registry

.
