wp_notify_postauthor

Отвечает за email уведомление автора записи, о том что к его записи был оставлен комментарий/пинг (comment/trackback/pingback). Отправляет email уведомление.

Работа функции зависит от: Настройки > Обсуждение > Отправить мне письмо, когда > Кто-нибудь оставил комментарий:

Чтобы изменить текст уведомления, тему и заголовки письма, используйте фильтры:

  • comment_notification_text
  • comment_notification_subject
  • comment_notification_headers
Через фильтр comment_notification_recipients можно добавить email адреса кому будет оправлено уведомление. По умолчанию там только адрес автора записи.

Можно переопределить в плагине. В этом случае эта функция использоваться не будет, а будет работать та что определена в плагине.
Хуки из функции:
comment_notification_headers
comment_notification_notify_author
comment_notification_recipients
comment_notification_subject
comment_notification_text
Возвращает

True/false. True – если письмо отправлено. False – если не удалось получить комментарий или если не указан ни один email адрес.
