paidsub hook

[ZERO <ibis>]

I am trying to use the paidsub_build and paidsub_delete hooks to run a function however I can not seem to get it to work. I think that I am not getting the userid the correct way below is what I have tried:

PHP Code:

global $vbulletin;

require_once('./global.php'); 

function($user['userid']); 


PHP Code:

global $vbulletin;

require_once('./global.php'); 

function($user[userid]); 


PHP Code:

function($user[userid]); 


PHP Code:

function($user['userid']); 


PHP Code:

function($userid); 


PHP Code:

global $vbulletin;

require_once('./global.php'); 

function($userid); 


PHP Code:

global $vbulletin;

require_once('./global.php'); 

function(paymentinfo['userid']); 


What am I doing wrong here?
