reading forumid, threadid, postid from init_startup

[mimidov]

I am able to read forumid, threadid, and postid (of forumdisplay, showthread, showpost) in init_startup using $_REQUEST[f], $_REQUEST[t], and $_REQUEST[p] respectively.

However, with Friendlyurl is enabled, these $_REQUEST vars are no longer working. How could I extract the forumid, threadid, and postid from the URL in case Friendlyurl option is enabled? Or else, how to know the forumid of a thread or post within init_startup.

Don't quote me on this, but I believe that in the startup there are global variables for them:
$forumid
$threadid
$postid

you tried this using GPC function?

Is there any way to pull out the usergroupid from init_startup?
