if can advise me how keep iframe open after form has been submitted appreciated.

you need change form submission use ajax. in response can include state flag indicate ui whether request successful or not , act appropriately. this:

$('#register_form').submit(function(e) {     e.preventdefault(); // stop standard form submission     $.ajax({         url: this.action,         type: this.method,         data: $(this).serialize(),         success: function(data) {             if (data.success) {                 // show success message in ui and/or hide modal             } else {                 // didn't work             }         },         error: function(xhr, status, error) {             // went wrong server. diagnose above properties         }     }); }); 

$success = false; if (isset($_post['deposit'])) {     if (isset($_session['fbid'])) {         $uid = $_session['fbid'];         $amount = $_post['amount'];         $cc = $_post['cc'];         $csv = $_post['csv'];          $bal = getbal($uid);         $newbal = $bal + $amount;         $sql = "update members set balance='$newbal' member_nr='$uid'";         $result = mysql_query($sql) or die("error please try again");            if ($result) {             $success = true;         }     } }  echo json_encode(array('success' => $success));
