I'm trying to implement advanced Google Analytics E-commerce, specifically, logging the addition/removal of a product).
I was surprised to see that no hooks exist for the cart when a product is added/removed which is why I am suggesting the following hooks:
ShoppingCartAddProduct - Called when a product is added to the cart
ShoppingCartRemoveProduct - Called when a product is removed to the cart
Both hooks would contain details of the product added/removed.
I'm sure I can't be the only person who would benefit from this!
