edit shopping cart class

[lilfo]

Hi guys, i'm new here..

i'm doing some mods to a zencart site and i need some help..

i'm trying to let user add a product in the cart in a new row when that product is also in the cart..
normally zencart updates the quantity (if the product is the same and the attributes too) but i need to show a different row in the cart for every time user click on the "add to cart" button..

in includes/classes/shopping_cart.php there is a function "add_cart" that checks if the product is also in the cart:

if ($this->in_cart($products_id)) {
$this->update_quantity($products_id, $qty, $attributes);
} else {
//add the product
}

i tryed editing the code like that but nothing:

//alway execute the code to add product (no qty update)
if (false /*$this->in_cart($products_id)*/) {
$this->update_quantity($products_id, $qty, $attributes);
} else {
//add the product
}

do you know how to do what i need?

p.s. sorry if this isn't the right place for this thread

ok i found this code in the actionaddproduct function (shopping cart class):

$this->add_cart($_POST['products_id'], $this->get_quantity(zen_get_uprid($_POST['products_id'], $real_ids))+($new_qty), $real_ids);

edited as

$this->add_cart($_POST['products_id'], $new_qty, $real_ids);

so now, every time i press on add to cart i add the product with the quantity i typed in the qty box..

now the problem is in $_SESSSION['cart']:

shoppingCart Object ( [contents] => Array ( [12] => Array ( [qty] => 1 ) ) [total] => 49 [weight] => 10 [cartID] => 04541 [content_type] => [free_shipping_item] => 0 [free_shipping_weight] => 0 [free_shipping_price] => 0 )

i can't have two rows in an array with the same key, so with my edited code i can't insert the new product in the cart..

if i add some letters in the key (so changing the product id) i think i can have problem.. i will not only if zencart uses intval function when read the product id (but i don't think so..)

any idea on how to solve it?

Can you please explain the business problem you're trying to solve here?
If you explain why you're trying to do that, perhaps the solution might be simpler than you think. But without knowing the bigger picture it's hard to give the right answer.

thank you anyway drbyte, i just solved adding an hidden text option to all products filled with an increasing number :)
