Automatically Add Item to Cart

I know this has been asked a couple different ways in forum posts a couple years back, but I just cannot figure it out. I need to automatically add a product or "fee" to the cart when a shopper clicks on a product in a certain category of my shop.

Or, if I can add a link to an article that adds the product to the cart, and then redirects the shopper to the specific category in my shop. I don't need this fee to be added for every product in my shop, just the certain products in one of the categories.

Hi,

For that it will require custom code, you will have to make a plugin based on the function:
onAfterCartUpdate(&$cartClass,&$cart,$product_id,$quantity,$add,$type,$resetCartWhenUpdate,$force)

Here is some documentation:

We don't have this kind of option yet in HikaShop, but it's on our todo list: Add an item when using coupon.
