Detail User(PHP)

<?php
 $id = $_POST['id_data'];

$qry = mysql_query("SELECT * FROM t_users WHERE id='$id'");
while($data = mysql_fetch_array($qry))
{
?>
<table width="100%" border="1">
  <tbody>
    <tr>
        <th colspan='3'>
            Detail Data Users
        </th>
    </tr>
    <tr>
      <td>ID</td>
      <td>NAME</td>
      <td>STATUS</td>
    </tr>
    <tr>
      <td><?php echo $data['id']?></td>
      <td><?php echo $data['name']?></td>
      <td><?php echo $data['status']?></td>
    </tr>
  </tbody>

Scenario :
When button Detail User is click run Jquery and value checkbox and then send to modal bootstrap, then post from jquery run code php to show result data from database on modal bootstrap.
