Met deze code worden de custom producten van YITH FBT plugin gehaald uit een extra veld per categorie. Een product heeft OF 1 categorie OF meerdere categorieen en (via Yoast SEO) een primaire categorie. Indien het op custom products staat zal het altijd worden getoond, mits er upsells zijn.
In de website
Met ACF een post object field maken en koppelen aan product_cat. (het veld moet ID’s terug geven) –> upsells_categorie = slug
