Should I be recalling session_start?
As a general rule, you should call session_start() in *every* PHP script that accesses $_SESSION. Where you call it depends on whether you're using output buffering or not[1], but it must *always* be *before* you access $_SESSION for the first time in that script. [1] If you're not using output buffering ( http://us.php.net/manual/en/ref.outcontrol.php), then you *must* call session_start() *before* any output is sent to the browser, otherwise you'll get a "can't send headers because headers were already sent" error (this means that the call to session_start() should probably be the very first thing your script does). If you are using output buffering, then you can call it pretty much anywhere in your script before you send the contents of the output buffer to the browser. -- Aaron Heimlich Web Developer [EMAIL PROTECTED] http://aheimlich.freepgs.com
