Bu benim php kodu:

if (isset($_POST['data']) && is_array($_POST['data'])) {
                foreach ($_POST['data'] as $row => $data) {
                    $result = mysql_query("UPDATE orders SET project_ref='".$data['project_ref']."' where order_id = '".$data['order_id']."'") or die(mysql_error());
                    $result1 = mysql_query("UPDATE orders SET supp_short_code='".$data['supp_short_code']."' where order_id = '".$data['order_id']."'") or die(mysql_error());
                    $result2 = mysql_query("UPDATE orders SET om_part_no='".$data['om_part_no']."' where order_id = '".$data['order_id']."'") or die(mysql_error());
                    $result3 = mysql_query("UPDATE orders SET description='".$data['description']."' where order_id = '".$data['order_id']."'") or die(mysql_error());
                    $result4 = mysql_query("UPDATE orders SET quantity='".$data['quantity_input']."' where order_id = '".$data['order_id']."'") or die(mysql_error());
                    $result5 = mysql_query("UPDATE orders SET cost_of_items='".$data['cost_of_items']."' where order_id = '".$data['order_id']."'") or die(mysql_error());
                    $result6 = mysql_query("UPDATE orders SET cost_total='".$data['cost_total_td']."' where order_id = '".$data['order_id']."'") or die(mysql_error());
                }
            }

Kullanıcı sipariş kimliği düzenlemek isteyen Yani: 1, i order_id 1 tüm satırları güncelleme umuyoruz, ama ne bu kod yapıyor "1" tüm alanları belirliyor?

EDIT:

Bu benim PHP veri yolluyorum nasıl:

$('#submit').live('click',function(){               
                    var postData = {};
                    postData['data[order_id]'] = $('#order_id').text();
                    $('#items tr').not(':first').each(function(index, value) {
                        var keyPrefix = 'data[' + index + ']';
                        postData[keyPrefix + '[supp_short_code]'] = $(this).closest('tr').find('.supp_short_code').text();
                        postData[keyPrefix + '[project_ref]'] = $(this).closest('tr').find('.project_ref').text();
                        postData[keyPrefix + '[om_part_no]'] = $(this).closest('tr').find('.om_part_no').text();
                        postData[keyPrefix + '[description]'] = $(this).closest('tr').find('.description').text();
                        postData[keyPrefix + '[quantity_input]'] = $(this).closest('tr').find('.quantity_input').val();
                        postData[keyPrefix + '[cost_of_items]'] = $(this).closest('tr').find('.cost_of_items').text();
                        postData[keyPrefix + '[cost_total_td]'] = $(this).closest('tr').find('.cost_total_td').text();
                    });

                $.ajax
                    ({
                    type: "POST",
                    url: "updateorder.php",
                    dataType: "json",
                    data: postData,
                    cache: false,
                    success: function()
                        {
                            alert("Order Updated");
                        }
                    });
            });
