I wonder if this could be simplified somehow by the fact that much of the info in that array is going to be the same for every one of the attributes I’m trying to add. I’m really stuck with this – WooCommerce is well developed as a one-size-fits-all system, but the client wants the product entry streamlined for his very specific application, where products will have three and only three attributes. He enters many products and wants to eliminate any extra clicks. In the default new product process, adding attributes requires several clicks that seem unnecessary.
