AddToCart product item (id)

i'm trying to get the id of the current item i'm trying to put into the cart to check for attributes before adding it. i've found that _AddToCart.cshtml uses the ProductDetailsModel, but i'm not sure how to use that in another context aka action filter. could someone please provide a quick code example?

please someone give me a hint. this must be something very obvious i'm missing.

Maybe this what you're referring to -

  public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            base.OnActionExecuting(filterContext);

            if (filterContext.ActionParameters.ContainsKey("shoppingCartTypeId"))
            {
                int cartTypeId = 0;
                bool hasCartTypeId= int.TryParse((filterContext.ActionParameters["shoppingCartTypeId"] ?? string.Empty).ToString(), out cartTypeId);
            }

            if (filterContext.ActionParameters.ContainsKey("productId"))
            {
                int productId = 0;
                bool hasProductId = int.TryParse((filterContext.ActionParameters["productId"] ?? string.Empty).ToString(), out productId);
            }
            
        }

You could make productId and cartTypeId instance properties to access them OnActionExecuted.  

Hope that helps, friend!
