alert when adding a product to shopping cart

[Retro]

I'm using this contribution:

1. Open catalog/includes/header.php
add this on top:
// language definition
define('PRODUCT_ADDED',add_cart);

// give alert if new product added to the cart
if (tep_session_is_registered('new_products_id_in_cart')) {
echo '<script>alert(\''.PRODUCT_ADDED.'\');</script>';
}


2. open your language definition (ie: catalog/includes/language/italian.php):
add this:
define('add_cart', 'Product was added to your basket!');

 

the problem appears when I add to cart a product with attributes, since that each visited page in my store displays the alert :blink:
