ผมว่านะครับถ้าเป็นการตรวจสอบว่าใส่ยูสเซอร์หรือรหัสผ่าน ยังใช้แค่จาวาสคริบ ตรวจก่อนก็ได้มั้ง ถ้า textbox ว่างก็แสดงข้อความเลยไม่ต้องไปตรวจสอบที่อีกไฟล์ก็ได้นะ
หรือว่าถ้าจะทำแบบนี้จริงๆข้อความที่ส่งมาก็ลอง encode ก่อนแล้วค่อยมา decode ที่หน้าแรกแล้วค่อยแสดง
หรือใส่นี่ เข้าไปที่ ajaxphploginform2.php
Code (PHP)
header("Content-Type: text/html; charset=utf-8");//ทำให้แสดงข้อความที่เป็นภาษาไทยได้
