做了一个搜索数据功能，有点问题达人们进来看看....

if($_POST['select_buton']=='查询'){
      $choose_area=$_POST['choose_area'];
      $search=$_POST['search'];
      $sql=mysql_query("select * from tbl_area where $choose_area like '%".trim($search)."%'");
      }
  $row=mysql_fetch_object($sql);
  do{
  ?>
  <tr>
      <td><?php echo $row->ID;?></td>
    <td><?php echo $row->arSN;?></td>
    <td><?php echo $row->arName;?></td>
    <td><?php echo $row->arUpSN;?></td>
    <td><?php echo $row->arIsHide;?></td>
    <td><?php echo $row->arOrder;?></td>
  </tr>
  <?php 
  }while($row=mysql_fetch_object($sql));
    }
  ?>

<?php
if($_POST['select_buton']=='查询'){
    $choose_area=$_POST['choose_area'];
    $search=$_POST['search'];
    $sql=mysql_query("select * from tbl_area where $choose_area like '%".trim($search)."%'");
    while($row=mysql_fetch_object($sql)){
?>

      <tr>
      <td><?php echo $row->ID;?></td>
      <td><?php echo $row->arSN;?></td>
      <td><?php echo $row->arName;?></td>
      <td><?php echo $row->arUpSN;?></td>
      <td><?php echo $row->arIsHide;?></td>
