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


$this->registry->db


instead of


$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.


$this->registry &= $vbulletin;
All class attributes can be accessed within the class with $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:


$this->registry
.
