Jessica Posted February 26, 2007 Share Posted February 26, 2007 $_POST['quantity_'.$My_Variable] That is perfectly valid, as long as $My_Variable is 1, 2, 3, etc. Link to comment https://forums.phpfreaks.com/topic/40091-can-you-do-_postmy_variable/#findComment-193976 Share on other sites More sharing options...
