php - 搜索结果分页

Question

我想在搜索结果中进行分页。我有一页，有两个表，一个用于搜索，第二个用于结果。

    <form method="get">
<table align="center" border="1" cellpadding="10" cellspacing="10">
<tr>
<td>Username</td>
<td><input type="text" name="user"></td>
</tr>
<tr>
<td colspan="2" align="center">
<input type="submit" name="search" value="search">
</td>
</tr>
</table>
<table align="center" border="1" cellpadding="10" cellspacing="10">
<tr>
<th>User</th>
<th>Address</th>
</tr>
<?php
while($ft=$pge->fetch_object())
{
?>
<tr>
<td><?php echo $ft->user ?></td>
<td><?php echo $ft->address ?></td>
</tr>
<?php
}
?>
</table>
<center>
<?php
$totalrecords=$totalrecords/2;
for($i=0;$i<$totalrecords;$i++)
{
?>
<a href="pagination.php?pgid=<?php echo $i ?>"><?php echo $i+1  ?></a>
<?php
}
?>
</center>
</form>

默认情况下，我应用了分页，但是当我想通过搜索查找用户详细信息时，我也想在搜索结果中进行分页。但是我还没有完成。这是我的分页代码。

 require('connect.php');
 $sel="select * from submit";
 $ex=$cn->query($sel) or die($cn->error);
 //$ft=$ex->fetch_object();
 $totalrecords=$ex->num_rows;


 if(isset($_REQUEST['pgid']))
 {
   $pgid=$_REQUEST['pgid'];
   $pgn=$pgid*2;
   $pg="select * from submit limit $pgn,2";
   $pge=$cn->query($pg) or die($cn->error);

 }
 else
 {
   $pg="select * from submit limit 0,2";
   $pge=$cn->query($pg) or die($cn->error);
 }

 if(isset($_REQUEST['search']))
 {
  $u=$_REQUEST['user'];

  $searchquery="select * from submit where user like '%$u%'";
  $pge=$cn->query($searchquery) or die($cn->query);

 }

创建自定义 MySQL 查询试试这个代码:-

$pg="select * from submit where 1=1";
if(isset($_REQUEST['search']))
 {
  $u=$_REQUEST['search'];
  $pg.=" and user like '%$u%'";
 }
if(isset($_REQUEST['pgid']))
 {
   $pgid=$_REQUEST['pgid'];
   $pgn=$pgid*2;
   $pg.=" limit $pgn,2";
 }
 else
 {
   $pg.=" limit 0,2";
 }

 $pge=$cn->query($pg) or die($cn->error);
