php - Two Forms, One Button. Not sure of how to make this happen -

i have page prints out rows of information. in each row notes box:

<?php <td style='font-size:12px;width:300px;'> {$row['notes']} <br /><center><br />     <form action=\"http://********/functions/notes.php\" id='formnotesform' method='post'>     <input type='hidden' id='id' name='id' value='{$row['id']}' />      <textarea placeholder=\"add more notes here...\" name=\"notes\" rows=\"5\" cols=\"30\"'></textarea><br />     <input type='submit' name='formnotes' id='formnotes' value='add notes' />     </form>  </center></td> ?> 

then there's button on page in each row.

    <form action=\"http://********/functions/archive.php\" method='post' id='formarchiveform' onclick=\"return checkarchive()\">     <input type='hidden' id='id' name='id' value='{$row['id']}' />     <input type='submit' name='formarchive' id='formarchive' value='archive' style=\"height:25px; width:80px\"/>     </form> 

what need happen when clicks "add notes" button job when clicks "archive" button checks see if notes empty , if not submits (kind of failsafe).

ideally i'd pick notes data , post archived.php file form going anyways since cause minimal disruption code base can't work.

i understand isn't sensible choice. has done. help!

if had reputation ask first because understood want button has been pressed things.

if that's this:

if($_server['request_method'] == 'post') {   if(isset($_post['formnotes']))   {   //...   }   elseif(isset($_post['formarchive']))   {   //...   } }
