I am using WooCommerce and WooCommerce Brands which creates the taxonomy "product_brand".
I need to restrict the cart so that a customer can only purchase products from single "Brand", if they try to enter products from another brand into their cart it should display a message stating something like:
Products from multiple brands cannot be included within the same cart. (Button - "Clear Cart & Add")
It would be great if a button could also be added that allows the customer to "Clear Cart & Add" the product they were attempting to purchase.
