限制客户在Magento中为特定产品最多购买2件商品

Question

I currently have an issue trying to restrict customers to purchasing 2 of a product max.

So far, I can set the max number of the product in the cart to 2 using catalog/manage products, select the product, then inventory and adjusting the max Qty allowed in cart to 2.

However, this will not stop the user coming back another day and purchasing another 2 items.

What I would like to do is create a rule so that when the user logs in and tries to purchase the product, after already purchasing it, the code will throw an error saying that they have reached their max quantity and prevent the cart from processing the order.

I believe that I would have to edit one of the php files to run a check against the users id and the product id, but I am unsure which file will need to be edited.

Magento ver. 1.3.2.4

First of all create one observer checkout_cart_add_product_before

In this observer event check cart quantity of product, you can get qoute item from quote object and from quote retrieve product quantity and match with newly added product if condition satisfied then redirect customer to product details page with mesage
