I'm trying to update different rows from mysql that they filtered by some record . in this code first the user should enter two input : classnumber and level . records that they have this fields will show in table then the user should be able to update this records information . but the problem is all of records are in one table in mysql so their id is different I mean for example the first record that match with two inputs id is 2 and then the next one is 5 and next one 6 and ....
with this kind of situation how should I change the code below ?
<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);
}
