Cart: Add only products from 1 manufacturer

[israel_lanoa]

Hi experts,

 

I need to check when adding a new product to the cart, that if there is another product already added, the new product manufacturer is the same as the existing one.

 

That is, only allow a product manufacturer per order.

 

Would it be difficult this customization of the cart?. Is there something similar?

 

Thanks in advance.

Hello,

 

When adding a new product you would need to go through all the products in the cart, compare the manufacturer ID's. If ID found return error message e.g. 'You can purchase only........', if ID not found add to cart.
