如何将多种不同类型的产品添加到购物车

Question

I am creating a shopping cart where I am trying to add different types of product e.g. Mobiles, clothes etc. I have created a add_to_cart method and added products to session, then at last I save all products to database table. But now I am confused how to add different product because parameter for different products are different e.g.

1. product_id, quantity, price for mobile.
2. product_id, quantity, price, size for cloths.
....

should I create different add_to_cart() method for different types of products.

Answer 1

In your scenario it would be better to have the product options sent as a JSON string and then decode it on the server side so that you don't have to worry about the different options for each product.

So product one might have options like:

{color: "black", size: "large"}

And product two might have:

{memory: "2 GB", harddisk: "750 GB"}

etc.
