deleted_comment │ action-hook │ WP 2.9.0

Fires immediately after a comment is deleted from the database (before the cache is cleared).

After the hook fires, wp_delete_comment() performs the following actions:

• Updates (decreases by 1) the post's comment count — wp_update_comment_count()

• Deletes the comment object cache — clean_comment_cache()

• Fires the wp_set_comment_status hook

• Changes the status to delete — wp_transition_comment_status()
