wp_insert_post_empty_content хук-фильтрWP 3.3.0

Filters whether the post should be considered "empty".

The post is considered "empty" if both:

  1. The post type supports the title, editor, and excerpt fields
  2. The title, editor, and excerpt fields are all empty

Returning a truthy value from the filter will effectively short-circuit the new post being inserted and return 0. If $wp_error is true, a WP_Error will be returned instead.
