รบกวนขอผู้รู้หน่อยค่ะ อยากได้โค้ด อัพเดทอัตโนมัติเลยค่ะ เปลี่ยนสถานะก็ให้อัพเดทลงดาต้าเบสได้อัตโนมัติเลยค่ะ

function updateStatus(val, record_id) {
        $.ajax({
            url: '/update_status.php',
            data: { status : val, id : record_id},
            type: "POST",
            error: function () {
                alert("An error ocurred.");
            },
            success: function (data) {
                alert('Success');
            }

        });
}

...
...
