}
$school_sql=mysql_query($query);
$school=mysql_fetch_array($school_sql);

</td>



//Here code for display data 
    <td ><?php echo $result['payment_details'];?></td>
    <td ><?php echo $result['payment_date'];?></td>
    <td ><?php echo $result['amount_paid'];?></td>

Script tag added

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script type="text/javascript">

jQuery(document).ready(function($) {
      jQuery('#school_id').change(function(e){

          selected = jQuery('#school_id').val();
          window.location = window.location.pathname + '?id=' + selected;

      });
});

What's basically happening is, when you select a school_id , the jQuery change() function fires and appends the selected school_id to the current URL and goes to it. Now the URL has a id= school_id value which the PHP checks before executing the query. If there is one, it uses that value in its select statement.

Is this what you needed?
