Hi I'm trying to record the status of a user when they log out but I can't work out where I'm going wrong. Any help would be fantastic Cheers Chris Button <a href="<?php echo $logoutAction ?>">Log out</a> Log Out <?php //initialize the session if (!isset($_SESSION)) { session_start(); } // ** Logout the current user. ** $logoutAction = $_SERVER['PHP_SELF']."?doLogout=true"; if ((isset($_SERVER['QUERY_STRING'])) && ($_SERVER['QUERY_STRING'] != "")){ $logoutAction .="&". htmlentities($_SERVER['QUERY_STRING']); //Record log in and out Status $query=("UPDATE authorise SET authorise.authorise_status = 'Logged Out' WHERE authorise.authorise_username = '$_SESSION[MM_Username]'"); $result=mysql_query($query); } if ((isset($_GET['doLogout'])) &&($_GET['doLogout']=="true")){ //to fully log out a visitor we need to clear the session varialbles $_SESSION['MM_Username'] = NULL; $_SESSION['MM_UserGroup'] = NULL; $_SESSION['PrevUrl'] = NULL; $_SESSION["skill"] = NULL; $_SESSION["email"] = NULL; $_SESSION["firstname"] = NULL; $_SESSION["department"] = NULL; $_SESSION["fullname"] = NULL; unset($_SESSION['MM_Username']); unset($_SESSION['MM_UserGroup']); unset($_SESSION['PrevUrl']); unset($_SESSION['skill']); unset($_SESSION['email']); unset($_SESSION['firstname']); unset($_SESSION['department']); unset($_SESSION['fullname']); $logoutGoTo = "../index.php"; if ($logoutGoTo) { header("Location: $logoutGoTo"); exit; } } ?>
