可以利用pre_delete_post 过滤以缩短帖子的删除。

add_filter( \'pre_delete_post\', \'wpse_224246_pre_delete_post\', 10, 3 );
function wpse_224246_pre_delete_post( $delete, $post, $force_delete ) {
  //* Escape early if post isn\'t already trashed
  if( \'trash\' !== $post->post_status ) {
    return $delete;
  }
  //* Go ahead with deleting the post if the current user is the post author 
  if( get_current_user_id() === $post->post_author ) {
    return $delete;
  }
  //* Returning any other value besides null will short circuit the deletion
  return true;
}
