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 eg 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 eg

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.

Answer 2

As long as products have at least some common fields, writing different methods is not entirely justified.

The other attributes can simply be passed as key-value pairs.

When writing the data into a database, you could apply EAV modeling .

Answer 3

you can keep using the add_to_cart()

instead, you'll add an array parameter, say, "attributes" or "extra" and add there specific/unique product valued keys.

then in database you create an "attributes" column of variable size eg. VARCHAR(128) and add those attributes encoded as JSONs

you can still search for any product then using "LIKE '%"attribute" :%'" (json)

this doesnt forcing you to create additional columns for every new product attribute.

Answer 4

You can keep basic common things in primary array and specification in specification array as follows Products[mobile] =>array(name => 'test1', price =>'20' specification=array('color'=>red,model=>'N70' etc....))

Products[cloths] =>array(name => 'test1', price =>'30' specification=array('size'=>'XL',color=>'yello',etc......))
