Need help writing script

Recommended Posts

I posted this in the newbie forum, but I think it might be a little too advanced for there. What I'm trying to do is integrate geeklog with webcalendar. I want it so users can log into geeklog, and the cookie that webcalendar reads will be written. This way, when the calendar is accessed, it looks like their info is saved and doesn't require them to login.


Here is the login file for the webcalendar. This is login.php, the page that users go to login. As you can see, it uses its self as the action in the form.

I just need to call a function that will give the same end result of writing the cookie. Please help...all advice appreciated.
