trq Posted August 21, 2007 Share Posted August 21, 2007 Have you read the big HEADER ERRORS sticky at the top of this forum? Quote Link to comment Share on other sites More sharing options...
MadTechie Posted August 21, 2007 Share Posted August 21, 2007 well the following code is fine.. you sure your not including it or something? <?php // Start the session session_start(); // Process actions $cart = $_SESSION['cart']; $action = $_GET['action']; switch ($action) { case 'add': if ($cart) { $cart .= ','.$_GET['id']; } else { $cart = $_GET['id']; } break; case 'delete': if ($cart) { $items = explode(',',$cart); $newcart = ''; foreach ($items as $item) { if ($_GET['id'] != $item) { if ($newcart != '') { $newcart .= ','.$item; } else { $newcart = $item; } } } $cart = $newcart; } break; } $_SESSION['cart'] = $cart; ?> Quote Link to comment Share on other sites More sharing options...
scadran Posted August 21, 2007 Author Share Posted August 21, 2007 what am i including? nothing really .... The page is displayed completely and correctly ... but i need to know why should i have that warning at the very top of the page!? is there something wrong with this part? echo $cart; $cart = $_SESSION['cart']; require_once('inc/functions.php'); include('config.php'); ?> cause this is the only part which i ve included and then recieved the warning!?

trq Posted August 21, 2007 Share Posted August 21, 2007 is there something wrong with this part? Yes. You cannot echo ANYTHING prior to calling session_start() or header(). Once again I ask...
