Which Hook to access forumid / userid before display?

[smjChris]

Hello,

I have a script that places images (banners) where I choose, but for logging purposes I need to access the vBulletin $foruminfo['forumid'] & $bbuserinfo['userid'] variables.

I have placed the include file (through plug-in system) in global_start, and the images are displayed, but are missing the forumid / userid elements.

Which hook should I place my include into so I can access those variables and still be able to insert my output within the templates for display?

sample code of what I'm trying to do...

PHP Code:

//set userid = 0 for default/guest
$x_userID=0;
if (isset($bbuserinfo['userid'])){
    $x_userID = $bbuserinfo['userid'];
}

//build url for anchor
$myUrl = "ad_Hit.php?";
$myUrl .= "adid=".$adArray['adid']."&uid=".$x_userID;

$myAnchor = "<a href='".$myUrl."'><img src='".$imgPath."' border='0' hspace='3' vspace='3' alt='".$adArray['company']."'></a>"; 


constructed querystring is parsed in additional script and I need to log the userid if user is a registered user, not default of 0/guest


Thank you.
