How do i make a 'log out' button with postgresql?

[iNko]

Hey again, was making a registration form with php and postgresql and  im stuck at making a 'log out' button, i need to make something simple like - press on a link, it redirects u to the index page and if u try to go 'back' it wouldn't let u..

 

I found something on google like this:

<a href="test.php?logout=1">Log out</a>

 

and on test.php:

<?php
if(isset($_GET['logout'])){
session_unset;
session_destroy;
}
?>
Succesfully logged out, go back to index page: <a href="index.php">Home</a>

 

but i didnt use any sessions at all.. is there something like 'session_destroy' with postgre? i mean smth like 'pg_desroy'?

I don't know anything about postgre, but, you're not checking for the existence of a session, nor the proper value of a session being set, nor even the proper value of logout.

How is the user logged in? Is it a cookie or something, show us your login code.

postgre has noting to do with login/logout.
