搜索多个字段

Question

我有一个名为在杆状，经验，公司该表的几个字段当前表等

我想要有三个选择框一个呈现搜索来自post字段的帖子，第二个显示experience和第三个显示来自单个当前表格的company。

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

为此，我编写了代码，但其无法正常工作，请帮助我找到我出错的地方，我无法理解。

它只显示在后栏输入的数据，但不在其他栏中输入。

我的代码放在这里

<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> 

我的搜索代码放在这里

<?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['noj'];?></td> 
    <td><?php echo $rows['cname'];?></td> 
    <td><?php echo $rows['jloc'];?></td> 


    </tr> 
    <?php 
    }}
