Some code from my pages , Page1 ( Redirecting page ) <html> <title>login_redirect.</title> body> <form name="redirect" action="http://mysite/page2.php" method="post"> <input type="hidden" name="mac" value="$(mac)"> </form> <script language="JavaScript"> <!-- document.redirect.submit(); //--> </script> </body> </html> Page 2 ( select product ) <?php session_start(); ini_set('display_errors',1); error_reporting(E_ALL); include '../lib/config.php'; include '../lib/opendb.php'; // get user mac adres from redirect post page1 $_SESSION['macid'] = $_POST['mac']; // set $macid for other use ( maybe not needed, am learning ) $macid = $_SESSION['macid']; // echo $macid does show mac adress, so variable is not empty here if (!empty($_POST["submit"])) { $product_choice = $_POST['accounttype']; $query= "SELECT AccountIndex, AccountCost, AccountName FROM AccountTypes WHERE AccountIndex='$product_choice'"; $result = mysql_query($query) or die('Query failed. ' . mysql_error()); while($row = mysql_fetch_array($result)) { $_SESSION['AccountIndex'] = $row['AccountIndex']; $_SESSION['AccountCost'] = $row['AccountCost']; $_SESSION['AccountName'] = $row['AccountName']; } header('Location: page3.php'); } // did leave out the other/html/form stuff here Page 3 ( show Session variables ) <?php ini_set('display_errors',1); error_reporting(E_ALL); session_start(); print_r($_SESSION); ?> Now, on page 3 i do see the right session varables, only the "macid" is empty. why ?
