Using session variables : start_session() before calling the session_is_registered() or even session_register(). Also make sure your sesion_register() is called like setcookie(), as header. Funny but true, I assumed that the session_register needs to kick off a session but unless you session_start(), cannot not register any variable. Also, if you are checking for any registered variable on an another page, again use session_start() before checking the variable value. But the session_start() doesnt start another session, so you will be fine with the values.
