Hi,
First, thank you very much for this fantastic plugin!
The shop has products (goodies) and donations. We need to issue a donation certificate for donations only. When the user puts a product in the cart, then a donation, the product is removed from the cart. That’s fine. But the user cann add a product to the cart after choosing a donation. Then the shop issues a donation certificate for the products and the donation combined. This is wrong.
Is there a way to allow only certain categories (donations) to sum up in the certificate?
The only solution we found is https://projectdmc.org/support/topic/exclude-specific-product-categories-from-invoices/ . By setting $not_allowed_cats to all other categories, we can avoid the sending of a donation certificate for products. But this also means that no donation certificates are generated in case of combined carts.
