    <form name="form_userprofile" method="POST" action="http://www.yayalearn.com/ABVFP/dbts_abvfp.php" enctype="multipart/form-data" id="Form1"
    <input type="hidden" name="f0_username" value="<?php echo $_SESSION['username'];?>">
    <input type="hidden" name="Formid" value="2">

    In other words, just give your hidden field the value

    <?php echo $_SESSION['username'];?>

    Of course this requires that you have already started a session. This is automatic if you have added in your page the Page Protect object.
