รบกวนช่วยหน่อยค่ะ Navigation page เมื่อคลิกหน้าถัดไป แต่ข้อมูลก็ยังแสดงอยู่ที่เดิมค่ะ
ช่วยดูให้หน่อยค่ะ
ทำยังไงก็ไม่ได้สักที เมื่อคลิกหน้าถัดไปข้อมูลก็ยังแสดงที่ชุดเดิม ไม่แสดงข้อมูลถัดไป
ไม่รู้ทำผิดที่ตรงไหนค่ะ

หากบรรทัดที่ 183 ให้เลือกแค่
Code (PHP)
while($objResult = odbc_fetch_array($objQuery) )
โดยตัด and $i<=$Per_Page ออก
มันก็จะแสดงข้อมูลออกมาทั้งหมดเลยค่ะ
รบกวนผู้รู้ช่วยแนะนำด้วยค่ะTag : PHP, Windows

140.$strSQL = "select * from customer order by Name1 asc";
141.$objQuery = odbc_exec($conn,$strSQL);
142.
143.$Num_Rows = odbc_num_rows($objQuery);
144.
145.$Per_Page = 10; // Per Page
146.
147.$Page = $_GET["Page"];
148.if(!$_GET["Page"])
149.{
150.$Page=1;
151.}
152.
บันทัดข้างบนแก้เป็นข้างล่าง เลือกเอาครับว่าเป็น Mysql หรือ SQLServer
Code (PHP)
<?php
// สำหรับ mysql
$Per_Page = 10;
$Page = isset($_GET['Page'])? $_GET['Page'] : 1;
$strSQL = 'select SQL_CALC_FOUND_ROWS * from customer
order by Name1 limit '.(($Page-1) * $Per_Page.','.$Per_Page;
$objQuery = odbc_exec($conn,$strSQL);
$rs_count = odbc_exec($conn,"SELECT FOUND_ROWS()");
list($Num_Row) = odbc_fetch_row($rs_count);
Code (PHP)
// สำหรับ SQLServer
$Per_Page = 10;
$Page = isset($_GET['Page'])? $_GET['Page'] : 1;
$strSQL = '
select * from
(select row_number() over (order by Name1 ) as row,* from customer) as t
where row between '.(($Page-1)*$Per_Page +1).' and '.($Page*$Per_Page);
$objQuery = odbc_exec($conn,$strSQL);
$rs_count = odbc_exec("SELECT count(*) from customer ");
list($Num_Row) = odbc_fetch_row($rs_count);
เอา && perpage ใน while ออกด้วย
หลักการคือการคิวรี่ เฉพาะสิ่งที่ต้องการ show เท่านั้น ไม่ใช่ ยกมาทั้งกระบิ มีกี่บันทัดคิวรี่มาหมดเลย
mysql มีคำสั่ง limit
sqlserver มีคำสั่ง row_number
