Как удалить товар, который принадлежит категории, когда его заказ завершен в WooCommerce

Question

Мне нужно выяснить, как удалить продукт (ы) из определенной категории, когда заказ, связанный с ним, завершен (помечен как завершенный) в WooCommerce.

Ниже приведен порядок настройки продукта.пользователям разрешено создавать продукт из внешнего интерфейса, а при создании продукта / продуктов он назначается определенной категории.После покупки пользователем, заказу присваивается продукт (ы).

Теперь я хочу иметь возможность автоматически удалять продукт после завершения заказа, назначенного продукту (ам).

Я проверил этот вопрос ( Как я могу удалить определенный товар из выполненного заказа в woocommerce? ), но мне это не помогло, а также этот вопрос ( Добавить временный продукт Woocommerce )

Ниже приведен код HTML для формы интерфейса

    die();
}

, но когда я сделал это вышеуказанным способом, я получилмного ошибок уведомления о неопределенных переменных, которые используются для создания поста.Я думаю, что это не правильный путь.Поэтому я хотел бы проверить, принадлежит ли продукт к категории ($product_CO_terms возвращает идентификатор для категории), и если заказ, связанный с продуктом (ами) в категории, завершен, то продукт должен быть удален или удален.

Спасибо
