[SOLVED] Retreiving A PHP Variable in Session?

[kyleldi]

I've got a form that asks someone to enter a code before continuing to the next page.  This information is posted by the form using $_POST.  On the next page, I'd like a hidden field with that code in it, so I can post it to a different database and work with it there.  Is there a way to obtain what was posted w/o passing it through the URL?  The Session is open on both pages, so I'd be left to believe it's available, I just don't understand how to call for it w/o using a URL variable.

p1.php

<?php
session_start();
$_SESSION['foo'] = 'bob';
echo "<a href='p2.php'>click</a>";

 

p2.php

<?php
session_start();
if (isset($_SESSION['foo'])) {
  echo $_SESSION['foo'];
}
