(Or would these even happen?) // Only needed if all authentication handlers fail to return anything. $user = new WP_Error('authentication_failed', __('<strong>ERROR</strong>: Invalid username or incorrect password.')); } $ignore_codes = array('empty_username', 'empty_password'); if (is_wp_error($user) && !in_array($user->get_error_code(), $ignore_codes) ) { do_action('wp_login_failed', $username); } return $user; } endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif; endif;
