• Answer:

  <?php ?> <!--beginning of the HTML page, up to the dropdown--> <?php $con = mysql_connect("localhost","root",""); //rest of your php code <?php while ($row=mysql_fetch_array($result)) { ?> <SELECT name= caName id="caName"> <OPTION VALUE=?<php echo $id; ?>><?php echo $thing; ?></option> <?php } ?> </select> I did this off the top of my head, so there may be some typos.
