using sesion_is_registered() depends on a couple things: 1. register_globals is on 2. you are using a super old method of using sessions. 1. if you're relying on register_global to be on that is usually frowned upon. The best method to do sessions is usually with $_SESSION, if you're not using an archaic versionn of php. // start session session_start() // set a session var $_SESSION['var'] = 'a value'; // check session existence if (isset($_SESSION['var']) ) ... // unset session var unset($_SESSION['var']); 2. read http://php.net/session a couple of time's to verify correct usage. and *do* take not of the "warning" sections.
