[PHP-NOTES] note 130441 added to function.session-destroy

I have provided a solution to avoid opening of pages directly through url without entering login page.. hope this serves the purpose.

session_start();
if (!isset($_POST['loginid']) && !isset($_SESSION['loginid']))
    echo "<script language=javascript>{alert('Please Log in..'); window.open('index.php','_parent')}</script>";
