How do I do that? Use of session_register() is deprecated in favor of direct access to the $_SESSION array -- which is present if session_start() has been called: <?php session_start(); $_SESSION['foo'] = 'bar'; // retrieve a session variable $bar = $_SESSION['bar']; // set a session variable ?> -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association | http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:matthew@garden.org | http://vermontbotanical.org
