You probably set $_SESSION['pid'] = $_POST['pid'] in every request - even if your POST doesn't even have pid in it.

Try to change this

$_SESSION['pid']=$_POST['pid'];

to this

if (isset($_POST['pid'])) {
  $_SESSION['pid'] = $_POST['pid'];
}

header('location:shoppingcart.php'); is a forced redirect, there is no POST when this happens, so the line $_SESSION['pid']=$_POST['pid']; is going to have no effect. If you must do cookieless sessions, look into use-trans-sid: http://www.php.net/manual/en/session.configuration.php#ini.session.use-trans-sid
