wp_delete_post

Удаляет запись из Базы Данных (пост, вложение, страницу).

При удалении записи, также удаляются все данные связанные с ней, это произвольные поля, комментарии, связь с разделами (таксономией).

  • wp_delete_post() передает управление функции wp_trash_post(), если параметр $force_delete=false, тип записи равен post или page, запись еще не в корзине и функция trash не выключена.

  • Использует: событие (action) delete_post до удаления записи, не распространяется на тип записи attachment.

  • Использует: событие (action) deleted_post после того, как запись удалена, не распространяется на тип записи attachment.

  • Использует: wp_delete_attachment(), если тип записи attachment.

Возвращает

Объект (WP_post)/false. false при неудачной попытке удаления и объект wpdb, при удачном удалении.
