使用PHP搜索MySQL数据库并返回分页结果

我遇到了一个问题，但任何帮助，将不胜感激。当我使用从表单中发布的结果查询数据库时，分页工作最初适用于前10条记录，但是当我点击第2页结果的分页的2个超链接时，它将丢失$_POST变量并返回到完整的数据集。保持这些变量可用于第二（和更多）页面的最佳方式是什么？使用PHP搜索MySQL数据库并返回分页结果

以下是我完整的php文件。

<html> 
<head> 
<link rel="stylesheet" type="text/css" 
href="design.css">

<body> 

<?php 
include("header.php");

<center> 
<div id="content" class="frm">

include("../config.inc"); 
    $find=$_GET['find'];   
      // get page no and set it to page variable, if no page is selected so asign first page bydefualt 
      if (isset($_GET["page"])){ 
        $page = $_GET["page"]; 
       } 
       else { 
        $page=1; 
       } 
       // count all record in this table then divide it on 10 in order to find the last page----- every page has 10 record display 
        $sql = "SELECT COUNT(*) FROM tt where TTT='$find' "; 
        $rs_result = mysql_query($sql); 
        $row = mysql_fetch_row($rs_result); 
        $total_records = $row[0]; 
        $total_pages = ceil($total_records/2); 
        // this line check that page no must be in integer format 
        $page = (int)$page; 
        if ($page > $total_pages) {

        $start_from = ($page-1) * 2;

将$ find添加到链接中，就像使用$ page一样。这是大多数网站在搜索时所做的。 – 2012-03-22 05:54:02

您必须将过滤条件和指向下一页的链接一起传递。

echo " <a href='{$_SERVER['PHP_SELF']}?page=1&find=$find'><<</a> ";

等与其他链接。
