pozdrav svima!
problem sto nije hteo da puni korpu je bio usledecem, u liniji --> <td><a href="index.php?page=products&action=add&id=<?php echo $row['id_products']; ?>">Add to Cart</a></td> je umesto, =add&id stajalo =add$id . i u bazi je pisalo id_product, i to sam prepravio u id_products , onda je pocelo da puni korpu. takodje i onu zagradu sam stavio sto je Pavle naveo. Sada sve radi, puni korpu, mogu da je updateujem, samo stalno gore stoji sledece greska -->Notice: Undefined index: quantity- in C:\wamp\www\tutorials\cart\cart.php on line 9 , a DW nigde mi ne javlja gresku.
Evo koda:
<?php
if (isset($_POST['submit'])){
foreach($_POST as $key => $value) {
$key = explode ("-", $key);
$key = end($key);
$key = explode("submit",$key);
$key = end($key);
if ($_POST['quantity-'.$key] <= 0){ // ovo je linija 9
unset($_SESSION['cart'][$key]);
} else if($_POST['quantity-'.$key] >= 50) {
$_SESSION['cart'][$key]['quantity'] = 50;
} else {
$_SESSION['cart'][$key]['quantity'] = $value;
}
}
} error_reporting (0);
?>

$query = mysql_query($sql);
if(empty($query)) {
