Я пытался изменить код, на основе продукта SLUG, но без каких-либо успехов
, что я сделал, было изменить код на используйте SKU продукта вместо SLUG продукта
Таким образом, это вопрос изменения настроек в вашем коде, так что вместо $product_id, будет использоваться $product_sku.
Обратите внимание, однако, что теперь $product_id будет определяться на основе $product_sku, для дальнейшего хода вашего кода add_to_cart ... работает например, на основе добавления $product_id, а не $product_sku
