我試圖在搜索數據後進行分頁。在第一頁數據顯示,但如果點擊下一頁或頁碼沒有顯示。如果回到第一頁,那麼數據也會消失。請在這個問題上幫助我。搜索結果分頁不起作用

感謝

     $page_num = 1;

     } 
     $start = ($page_num-1)*$per_page; 

     $id=$_GET['id'];   
     $result = mysql_query("SELECT * FROM person where university = '$uni'");

好檢查的完整代碼:

<FORM NAME="form1" METHOD="get" ACTION=""> 
    <input type="text" name="university" value="" class="bgnone" > 
    <input name="search" value="search" class="bgnone" type="submit" > 
    </SPAN> 
</form> 

<table height="200px" style="border:3px black solid;border-radius:5px" width="550px"> 
<tr> 
<th colspan="2" height="40px" style="border-bottom:3px black solid">User Name</th>

<?php 
    if(isset($_GET['university'])){ 
     $uni=$_GET['university']; 
    $link=mysql_connect("localhost","root",""); 
    mysql_select_db("dbname",$link); 
    $q="select count(*) \"total\" from tablename where firstname='".$uni."'"; 
    $ros=mysql_query($q,$link) or die(mysql_error());

    $total_page=ceil($total/$dis); 
    $page_cur=(isset($_GET['page']))?$_GET['page']:1; 
    $k=($page_cur-1)*$dis; 

    $q="select * from tablename where firstname='".$uni."' limit $k,$dis"; 
    //echo "select * from tablename where firstname='".$uni."' limit $k,$dis";die; 
    $ros=mysql_query($q,$link); 
    while($row=mysql_fetch_array($ros)) 
    { 
     echo '<tr>'; 
     echo '<td width="10px" style="border-bottom:1px #a1a1a1 solid">'.$row['id'].'.';

     echo '</tr>'; 
    } 
    echo '</table>'; 
    echo '<br/>'; 
    if($page_cur>1) 
    { 
     echo '<a href="paging-ex.php?page='.($page_cur-1).'&university='.$uni.'" style="cursor:pointer;color:green;" ><input style="cursor:pointer;background-color:green;border:1px black solid;border-radius:5px;width:120px;height:30px;color:white;font-size:15px;font-weight:bold;" type="button" value=" Previous "></a>';

    } 
    for($i=1;$i<$total_page;$i++) 
    { 
     if($page_cur==$i) 
     {

感謝您help.It工作。 – 2014-09-20 09:00:29

你會更好更換以下

if(is_numeric($_GET['page'])) 
       $page_num = $_GET['page']; 
      } 

通過

$page_num = int($_GET['page']); 
0

那麼,對於您的SQL查詢的正常運行,你需要$_POST['search']true$uni = $_POST['university']爲非空,對吧?目前,這些信息都不會通過點擊下一頁或頁碼傳遞給您的search.php

所以,你可能想改變你的分頁<a>標籤的東西,看起來像:

<a href='search.php?page=$next&university=$uni&search=true'>Next</a> 

並替換代碼的頂部使用$_REQUEST

if($_REQUEST['search']){   
    $uni=$_REQUEST['university']; 
    .... 

希望有所幫助。
