With modern versions of PHP, just use the $_SESSION array directly.

page1.php

session_start();
$_SESSION['MyVAR'] = 'Hans';


page2.php

session_start();
echo $_SESSION['MyVAR'];

Hmm, not too sure.  Double check that the javascript isn't doing anything wacky, because a hidden input can't be checked.
