Well, I don’t need any common functionality. I even don’t need either application to be wrapped by the other one’s layout – I just need the forum to supplement the main website on a separate autonomous screen. User registration and login should be done via Cake actions and I think I couldn’t do without programatically adding the users record in vBulletin’s core user DB tables and setting the appropriate session and cookie variables that vBulletin would need to recognize a logged user.

I’m well aware that my comments may not be relevant for this post, the only reason I wrote here is because I spotted a common thing with programatically adding a thread and I was thinking similar about registration and log-in.
If you think this is way off-topic, feel free to remove my comments and I’d be happy to direct my inquiries to the CakePHP Google group (although I’m not hoping for any huge success in doing this, because I’ve searched the group messages and have only been able to find several inquiries similar to mine with hardly any follow ups).

I haven’t seen any articles covering this, but I suspect it *can* be done but will be a lot of work. Sort of similar to the Drake (Drupal + Cake) and Jake (Joomla + Cake) projects. I guess a lot depends on what exact functionality you need from vBulletin in your Cake app

do you know of any articles on how I could integrate CakePHP and vBulletin? I’m developing my main site with CakePHP 1.2 and I need the vBulletin to share the same userbase etc.

Thank you in advance!

Thanks
