[Resolved] session_destroy problems..

sturoy

Hi,

I have a site where members can log in, and if they are logged in, they get access to various extra areas in the site. If you are not logged in, you cannot view the other pages...

Now, I'm trying to do a 'logout' button... I've se the button action to load up a page called 'logout.php'. As the first thing on this page, the following appears:

<?php
session_unset();
session_destroy();
?>

You can ONLY see the logout button if you are logged in... and I'm using sessions to log users in... WHY then, do I get this messgae when logout.php loads up...?

Warning: session_destroy(): Trying to destroy uninitialized session in (location)/logout.php on line 3

Any help would be greatly appreciated. Thanks.

Did you do a session_start() first?
You have to session_start() to bring the sessions into the local scope before you can destroy them.
I haven't checked the man on this one so If I'm wrong can you flame me on two scores a) for getting the question wrong and b) for capitalising a word in the middle of a sentance

<?php
session_start(); // as noted before...got to have this
session_unset();
setcookie (session_name(), '', (time () - 2592000), '/', '', 0);
session_destroy();
then do whatever

GENIUSES!

Yep, that was EXACTLY the problem. Now I think about it, it seems clear that you've gotta get it there before you can destroy it....

Thanks very much for your help... simple when you know how, huh?
