Как автоматически удалять старые посты, при достижении определенного количество постов?

Question

[Pista]

Нужен сниппет, который будет удалять все посты, при достижении определенного количества постов на сайте. Например, при достижении 100 постов, срабатывает условия -> удаляем все посты.

Необходимо очищать две таблицы wp_postmeta и wp_posts
Нашел в сети такой кусок, но не совсем нужные условия и не работает. Ошибка

	if ( $posts_array ) {

		// Make sure that we actually have post ID's in the $delete_posts array

Как то так

add_action(
    'publish_post',
    function() {
        $args = [
            'numberposts' => -1,
            'fields'      => 'ids',
        ];

        $posts = get_posts( $args );

        if ( $posts && count( $posts ) >= 100 ) {
            foreach ( $posts as $post ) {
                wp_delete_post( $post, true );
            }
        }
    }
);
