Amount of products added to cart

Question

I am trying to set a item price based on other products added to the cart,

eg if there are 4 products 'table'(quantity 4) then product X should be +50€.

First of all i am checking if the product->getAttributeText('try') is not false.

In the second step i would like to see how many products are placed from this kind(table).

what i did was:

foreach ($cart->getAllItems() as $item) {
    $productQnty = $item->getProduct()->getQty();
}

But this is always null.

Answer 1

You should try using a "Shopping Cart Price Rule". Under Conditions, you can set it to only work if there are X number of products in the cart. If you need, you can also specify the rule to only work for a specific product.
