Question

我有一个名为current的表，该表中有几个字段，如post，experience，company等。

我想进行搜索，其中有三个选择框，一个显示来自post字段的帖子，第二个显示experience，第三个显示来自单个当前表的company。

我希望如果用户从任何一个选择字段中选择，或者从所有选择字段中选择，则应该从表中搜索相应的数据并显示仅与搜索相关的结果。

为此，我写了代码，但它不起作用请帮助我找到我哪里出错，我无法理解。

它仅显示在post字段中输入的数据，但不显示在任何其他字段中输入的数据。

我的代码在这里

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" name="">
<table>

<tr>
<?php
$ss=mysql_query("select * from current"); 

?>
<td><select name="post"><?php while($rr=mysql_fetch_array($ss))
{?><option value="<?php echo $rr['post'];?>"><?php echo $rr['post'];?></option><?php } ?></select></td>
<?php
$s11=mysql_query("select * from current"); 

?>
<td><select name="experience"><?php while($r11=mysql_fetch_array($s11))
{?><option value="<?php echo $r11['experience'];?>"><?php echo $r11['experience'];?></option><?php } ?>    </select></td>
<td>
<?php
$sss=mysql_query("select * from current"); 

?>
<select name="company"><?php while($rrr=mysql_fetch_array($sss))
{?><option value="<?php echo $rrr['cname'];?>"><?php echo $rrr['cname'];?></option><?php } ?></select></td>
<td><input type="submit" name="search" value="Search" /></td>
</tr>

</table>
    </form>

我的搜索代码在这里

   <?php
include('Admin/config.php');
    error_reporting(E_ERROR | E_WARNING | E_PARSE);
  if(isset($_REQUEST['search']))
  {
$post = $_REQUEST['post'];
$ex = $_REQUEST['experience'];
$company = $_REQUEST['company'];
$query = "select * from current where post like '%$post%' or experience like '%$ex%' or cname like '%$company%' ";
$res1 = mysql_query($query);
while($rows = mysql_fetch_array($res1))
{
?>
<tr>
   <td><?php echo $rows['date'];?></td>
  <td><?php echo $rows['post'];?></td>
  <td><?php echo $rows['qualification'];?></td>
  <td><?php echo $rows['experience'];?></td>
  <td><?php echo $rows['nop'];?></td>
   <td><?php echo $rows['noj'];?></td>
  <td><?php echo $rows['cname'];?></td>
  <td><?php echo $rows['jloc'];?></td>


   </tr><?php

  }}

  else
  {


    $s=mysql_query("SELECT * FROM current ORDER BY date DESC");



  while($rows=mysql_fetch_array($s))
  {
  ?>
   <tr>
   <td><?php echo $rows['date'];?></td>
   <td><?php echo $rows['post'];?></td>
   <td><?php echo $rows['qualification'];?></td>
   <td><?php echo $rows['experience'];?></td>
   <td><?php echo $rows['nop'];?></td>
    <td><?php echo $rows['noj'];?></td>
   <td><?php echo $rows['cname'];?></td>
   <td><?php echo $rows['jloc'];?></td>


   </tr>
   <?php
   }}
   ?>
   </table>
