Re[2]: [PHP] sessions help

Thanks to Julie and Stuart for helping me. With your direction, I got rid of the warning about the headers by putting the session_start() at the beginning of the file. Now I get a different sort of error when I try to retrive the session variable: ------------------------------- Warning: Undefined index: node in c:\program files\apache group\apache\htdocs\wan\getglobal.php on line 17 ------------------------------- Any ideas why? (Here's the exact code I've got) [sessions.php] <?php session_start();?> <html> <head> <title>A test</title> </head> <body> <?php

        function sessionSetNode ($node_id) {
                return ($_SESSION['node'] = $node_id);
        }

        sessionSetNode("10.2");

?> </body> </html> [getglobal.php] <?php session_start();?> <html> <head> <title>A test</title> </head> <body> <?php if (!empty($_SESSION)) {

      extract($_SESSION);

} else if (!empty($HTTP_SESSION_VARS)) {

      extract($HTTP_SESSION_VARS);

} function sessionGetNode () {

    return $_SESSION['node'];

} $n = sessionGetNode(); echo ("Node is $n."); ?> </body> </html> TIA, Leston
