我是通过表单，获取关键字，表单名字是sel_key
模糊查询后内容分页显示，显示下一页的那条语句要传递什么参数，点击下一页才会有内容显示，求帮忙
<?php
if (isset($_POST[sel_key]))
{
$key=$_POST[sel_key];
// echo"$key";
$sql=mysql_query("select * from tb_wishes where wishsort like '%".$key."%' or id like '%".$key."%' or QQ like '%".$key."%' or Picker like '%".$key."%' or content like '%".$key."%'order by id desc limit ".($page_num-1)*$row_per_page." ,$row_per_page",$conn);
while($result=mysql_fetch_array($sql))
{
?>
<td><?php echo $result['id']; ?></td>
<td><?php echo $result['content']; ?></td>
<td><?php echo $result['Picker']; ?></td>
<td><?php echo $result['wishsort']; ?></td>
<td><a target="_blank" href="http://wpa.qq.com/msgrd?v=3&uin=455367066&site=qq&menu=yes"> <?php echo $result['QQ']; ?></a></td>
<td><?php echo $result ['sendTime']; ?></td>
</tr>
<?php }?>
<?php }?>
<a href="u.php?page_num=1"> 第一页</a>
<a href="u.php?page_num=<?php echo ($page_num-1) ?>">上一页</a>
<a href="u.php?page_num=<?php echo ($page_num+1) ?>">下一页</a>
<a href="u.php?page_num=<?php echo $page_count ?>">最后一页</a>

如果写法正确的话，只需要传一个页数 就可以了实现了。页数你还是要初例化一下吧，每一页分多条数据，你还是要设置一下啥，我看你
$page_num$row_per_page都没有初使数据
$page_num=$_GET['page_num'];
