I think you want the session_start() and session_register() calls at the top
of the script, not buried in your if() statements.

Subject: [PHP] Help with session
> I have 2 functions on my page, RegisterUser, IsValidUser.
> RegisterUser looks in the querystring to see if you've passed a certain
key
> & value. If you have it populates a session variable called "ValidUser"
> with a 1.
> All that IsValidUser does, is check to see if the session variable
> "ValidUser" is a 1 or not.
>
> It doesn't work.
> RegisterUser (which sets session variables) is taking place before headers
> are written to the browser. I'm not gettin errors, but the problem is
that
> ValidUser isn't able to read the session variable for some reason.
>
> Any Ideas?
>
> Here is the code for these 2 functions:

> {
> if ($HTTP_SESSION_VARS["ValidUser"] == "1")
