Hey.

You simply set the appropriate element in the $_SESSION array to the value retrieved from the $_POST array.

All variables submitted through a form are put into the $_POST array (or the $_GET array, if you did not use the "post" method on the form). Then, to set the session, you just have to start the session and set the appropriate element.

[code=php]<?php
session_start() ;
$_SESSION['myElement'] = $_POST['myFormVariable '];
?>[/code]
(You may want to look into input validation, to ensure the security of your application.)
