a.php:

<?php session_start(); $_session['frompanel'] = "abcd"; ?> <form method="post" action="./b.php"> <input type="email" name="username" value="john@example.com"> </form>

b.php:

<?php session_start(); var_dump( $_session['frompanel'] ); var_dump( $_post['username'] ); echo '<a href="./_test.php">back form</a>';

result output after sending form (with come in in input):

string 'abcd' (length=4) string 'john@example.com' (length=16) form

n.b: utilize <label for="id-of-form">caption</label> instead of <div class="text inputcaption"></div>
