Question

我正在尝试更新mysql中不同的行，这些行是按照某些记录过滤的。在此代码中，用户首先应输入两个输入：classnumber和level。他们拥有此字段的记录将显示在表中，然后用户应该能够更新此记录信息。但问题是所有的记录都在mysql的一个表中，所以他们的id不同我的意思是例如第一个匹配两个输入id的记录是2然后下一个是5，下一个是6和.... / p>

在这种情况下我应该如何更改下面的代码？

<form id="searchform" method="post" dir="rtl" action=""> 
 level :<input name="level"  style="margin-top:5px; margin-left:6px;font-family: Tahoma,Geneva,sans-serif; font-size: 12px; margin-top: 5px; padding: 5px; width: 50px;" type="text" id="level" />
 classnumber :<input name="classnum"  style="margin-top:5px; margin-left:6px;font-family: Tahoma,Geneva,sans-serif; font-size: 12px; margin-top: 5px; padding: 5px; width: 50px;" type="text" id="classnum" />
 <input style="margin-top:10px; margin-left:120px; font-size: 14px;  padding: 5px 14px;" type="submit" value="جستجو" name="enter"   />
</form>

<?php
 if(isset($_POST['enter'])){
  $sql="SELECT * FROM  `".$tbl_name."` where classnum='".$_REQUEST['classnum']."' and level='".$_REQUEST['level']."' ";
  $result=mysql_query($sql,$link);
  $count=mysql_num_rows($result);
 }
?>

<div class="cleaner h30"></div>

 <form name="form1" action="" method="POST">
