int $post_ID, WP_Post $post, bool $update )
Fires once a post has been saved.
(int) Post ID.
(WP_Post) Post object.
(bool) Whether this is an existing post being updated.
wp_insert_post action fires once a post has been saved. You have the ability to set it to only fire on new posts or on all save actions using the parameters. Please see Plugin_API/Action_Reference/save_post for more information. Keep in mind that this action is called both for actions in the admin as well as anytime the wp_insert_post() function is invoked.
This action can be replicated by creating a conditional in a save_post action that excludes certain post statuses.
An important distinction of
wp_insert_post action is that it is fired after
update_post_meta has been called.
