如果强制删除cookie，则更新登录状态

Question

I have this problem which keeps me from pushing towards my login page. I know that when you log in you can create a security by means of cookies and session and so i did. But using this EditThisCookie add on in google chrome, if i delete my cookies then I must update my database status to inactive. But im stucked on how to do it. Can some one help me regarding this problem. My code below.

$user  = $_SESSION["user_id"];
$sesskey   = $_SESSION['sesskey'];
$firstname   = $_SESSION['firstname'];

if(count($_COOKIE) > 0) {

} else {
$sqlupses   = "UPDATE credentials set loginkey = '', access_status  = 'inactive' where user_id = '$user'";
die($sqlupses);
$ressess    = mysql_query( $sqlupses, $dbhandle );
session_unset();
session_destroy();
header('location:index.php?lvs=8');
exit();
}
