Setting external Who's Online info manually.

[durentis]

Been searching through the forums for how to set up external who's online information, but everything I find isn't quite what I want and I can't seem to make it work.

Here's roughly what I'm after:
I have a number of .php files (index.php, action###.php) that are MVC structured to bind things to Smarty templates. The forums are seperate, but I wrote a wrapper to allow site-wide login/registration without first going to the forum.

The next step, and I can't figure this out for the life of me (very frustrating!), is to make it so users appear in the Who's Online list. I don't want to show any part of the forums on my index.php or action###.php files, I just want them to signal vBulletin (set whatever has to be set in the database) so that someone else looking at the who's online list can see that so-and-so was last online at some time viewing action243.php.

I even have my own database wrapper, so I should be able to do it w/out including vBulletin's.. I just don't know what to insert/update properly.

Any thoughts on this would be muchly appreciated,
Durentis.
