      You should know by now that your must enclose any shown code within php or code tags!
      Read the Posting Guidelines before you show any more code here!

      As for your question: you cannot do it like this in PHP. A checkbox is a client object and cannot be interrogated (DOM-wise) with PHP.

      The usual way to handle checkboxes is to give the box a name (or an array name) and let the values be filled by the MySQL result values. After submission you interrogate the POSTed name field or array and extract the values from it. Like the following sample shows:

      [php]<?php
      if (isset($_POST['submit'])) {
      print_r($_POST['checkit']);
      exit;
      }
      ?>
      <form method="POST" action="a.php">
      <input type="checkbox" name="checkit[]" value="1" />
      <input type="checkbox" name="checkit[]" value="2" />
      <input type="checkbox" name="checkit[]" value="3" />
      <input type="submit" name="submit" value="Submit" />
      </form>[/php]
