echo $cart->get_quantity(tep_get_prid($product_info['products_id']));

would work (possibly) with attributes – haven't tested. Don't ever do more code than is necessary.

a product with attribute is like this: product_info.php?products_id=1{4}1{3}5

the function tep_get_prid strips out the options, to make it back to this: product_info.php?products_id=1

Someone from the french osc forum helped me and this would work with attribute:

$superid = $product_info['products_id'];
$products = $cart->get_products();
for ($i=0, $n=sizeof($products); $i<$n; $i++) {
$prid = tep_get_prid($products[$i]['id']);
if ($prid == $superid) {
$qtyencart = $products[$i]['quantity'];
echo"Vous avez $qtyencart unité de cet item dans votre panier actuellement.";
break;
}
}

Hope this can help someone!

Now I want to add this code also on the categorie page near each add to cart button..
this might be harder…

Bye

It's Will here…

You're code is very good but for a reason, it does'nt work if I want to use it with AJAX.

Like on my site… http://www.khe opsinternational.ca/catalog/product_info.php?products_id=1150

Very great website BTW !
