Multiple Update from one form

Hi I have a current application where I am listing a table of order details, where a fulfillment company can enter the tracking number and the cost of the shipment. At present, I have up to 40 orders displayed, and when they click on the Œupdate¹ button, the code executes as if ((isset($tracking1)) && (isset($kb_ship1))){ $update=mysql_query("UPDATE orders SET tracking='$tracking1',kb_ship='$kb_ship1' WHERE order_ref = '$ref1'",$link); } And this continues as tracking 2... tracking40. I would like to implement something like foreach ($_POST["ref"]){ $update=mysql_query("UPDATE orders SET tracking='$tracking',kb_ship='$kb_ship' WHERE order_ref = '$ref'",$link); } Instead, but I¹m not so sure how I can do this, given that form variables cannot be named the same etc. I¹m sure that there¹s a better way that the way in which I¹m doing it at the moment, so any input would be appreciated. Thanks Enda --
