分頁不起作用

我打算爲我的成員頁面做一個分頁，我創建了8個分頁號碼，從1到8，這樣當我點擊每個頁面時，它應該只顯示一行特定的數據庫表格，數據庫表由8行組成，但在我的代碼中，當我點擊時，正確的頁碼正在傳遞，但它不會更新並顯示特定的分頁行，請你幫我解決這個問題。 members.php分頁不起作用

<?php 
include('assets/page_header.php');

if(isset($_GET['page']))

<html> 
<head><title></title> 
<style> 
h1 { 
text-align:center;

    $renewaldate=mysql_real_escape_string($_POST['renewaldate']); 
    $maxborrowlimit=mysql_real_escape_string($_POST['maxborrowlimit']); 
    $status=mysql_real_escape_string($_POST['status']);*/ 
    ?> 
    <h1>MEMBERS PAGE</h1> 

<?php 
$str="select * from member LIMIT 1,1 "; 
$query1=mysql_query($str); 
echo "<table align='center'>";

改變你的第二個（'$ query1'）變量，並檢查它。 – Nawin

你需要在你的'$ str'查詢中加入'WHERE memno = $ page'之類的東西。但一定要清理，以防止sql注入 – Sean

「LIMIT」和「OFFSET」在哪裏？ –

您可以嘗試這樣的代碼：

<?php 
    include('assets/page_header.php'); 
    include('db/db.php'); 
?> 
<html> 
    <head><title></title> 
     <style> 
      h1 { 
       text-align:center; 
      } 
     </style> 
    </head> 
    <?php 
     /*$memno=mysql_real_escape_string($_POST['memno']); 
     $memname=mysql_real_escape_string($_POST['name']); 
     $address=mysql_real_escape_string($_POST['address']); 
     $phonenumber=mysql_real_escape_string($_POST['phno']); 
     $renewaldate=mysql_real_escape_string($_POST['renewaldate']); 
     $maxborrowlimit=mysql_real_escape_string($_POST['maxborrowlimit']); 
     $status=mysql_real_escape_string($_POST['status']);*/ 
    ?> 
    <h1>MEMBERS PAGE</h1> 

    <?php 
     $num_rec_per_page = 10;

     $str = "select * from member LIMIT $start_from, $num_rec_per_page"; 
     $query1=mysql_query($str); 
     echo "<table align='center'>"; 
     echo "<tr><th><MemberNumber</th><th>MemberName</th><th>Address</th><th>Phonenumber</th><th>RenewalDate</th><th>MaxBorrowLimit</th><th>Status</th><th colspan=2>Action</th></tr>"; 
     while($query2=mysql_fetch_array($query1)) 
     {

      echo "</tr>"; 
     } 
     echo "</table>"; 
    ?> 
    <?php 

     $sql = "select * from member"; 
     $rs_result = mysql_query($sql); //run the query 
     $total_records = mysql_num_rows($rs_result); //count number of records 
     $total_pages = ceil($total_records/$num_rec_per_page); 

     if($total_records > 0) { 
      echo "<a href='members.php?page=1'> ".'<'." </a> "; // Goto 1st page 
     } 

     for ($i=1; $i<=$total_pages; $i++) { 
      echo "<a href='members.php?page=".$i."'> ".$i." </a> ";
