เวลาค้นปรกติไปหน้าแรกใช่ป่ะ เช่น
?page=1&keyword=xxx
หน้า2ก็คล้ายกัน
?page=2&keyword=xxx
เวลาเราจะแสดงผลของหน้า 1 กับ หน้าอื่นก็เอา ตัวเลขหน้ามาคำนวณจากที่ได้ด้วย limit start, offset ใน mysql
หน้าอื่นก็สั่งค้นหาด้วยคำเดิมตาม url นั้น เช่น
select * from table where field like '%xxx%' limit x, y
คาดว่าปัญหาของคุณก็คือไม่ส่งคำค้นไปหน้าอื่นด้วย
