Adding Multiple Items to Cart with One Click

Question

We are launching a feature that allows customers to add multiple items to cart with a single click. How would you design a data layer to support this? Would you set up multiple product objects or use and array?

Does anyone have an example of how the add to cart would work? Do you fire the scadd event once or multiple times?

Any guidance here would be helpful!

If it were me, I would create a data layer that would set each product and it's corresponding data into a JSON list within my data layer, something like:

{
   "action" : "addToCart",
   "products" : [{
      "name" : "product 1",
      "sku" : "e4534533",
      "valuex" : "something",
      "valuey" : "something else"
   },{
      "name" : "product 2",
      "sku" : "t6555677",
      "valuex" : "something2",
      "valuey" : "something else2"
   },{
      "name" : "product 3",
      "sku" : "j565665",
      "valuex" : "something3",
      "valuey" : "something else3"
   }]
}

Then on the "Add To Cart" rule, I would process all of the three products listed, and build my s.products string, setting up the appropriate merchandising eVars, etc.

Now, when you track an scAdd event, you don't technically need to attach it to each item in your s.products list in product notation... adding the scAdd event once in your s.events is just fine... the scAdd will apply to all items in the cart....

Basically, in a report you would see:

		Cart Additions
Products		1
	product 1	1
	product 2	1
	product 2	1

Basically, one cart add for the group in the "total", and one cart add for each item when looking individually... if you really need to see "3" as the total, you will have to create a custom numeric event, that you can pass on each product, and would add up to "3" at the end:

s.products = ";product 1;;;event1=1;eVar1=e4534533|eVar2=something|eVar3=something else,;product 2;;;event1=1;eVar1=t6555677|eVar2=something2|eVar3=something else2,;product 3;;;event1=1;eVar1=j565665|eVar2=something3|eVar3=something else3";
s.events="scAdd,event1";

(or maybe you are using your SKU in product, and the product name in eVar1, for example)

Basically, in a report you would see:

		Cart Additions	Event 1
Products		1	3
	product 1	1	1
	product 2	1	1
	product 2	1	1

The way I see it, the "Cart Additions" would be the actual action of adding to the cart, but "Event 1" would be a total indicator of all products added to the cart.... you may not need this, but it's good to understand the distinction between the counter event, and the numeric event in this context
