添加子主题函数时，自定义帖子类型不起作用

我正在尝试通过子主题注册帖子类型function.php 但它不起作用。但是，当我添加父项时，效果很好functions.php.

add_action( \'init\', \'testimonial\' );
if ( ! function_exists( \'testimonial\' ) ) :
function testimonial() {
    register_post_type( \'testimonial\',
        array(
            \'labels\' => array(
                \'name\' => \'Testimonial\',
                \'singular_name\' => \'Testimonial\',
                \'add_new\' => \'Add New\',
                \'add_new_item\' => \'Add New Testimonial\',
                \'edit\' => \'Edit\',
                \'edit_item\' => \'Edit Testimonial\',
                \'new_item\' => \'New Testimonial\',
                \'view\' => \'View\',
                \'view_item\' => \'View Testimonial\',
                \'search_items\' => \'Search Testimonial\',
                \'not_found\' => \'No Testimonial found\',
                \'not_found_in_trash\' => \'No Testimonial found in Trash\',
                \'parent\' => \'Parent Testimonial\'
            ),
            \'public\' => true,
            \'menu_position\' => 15,
            \'supports\' => array( \'title\', \'editor\', \'comments\', \'thumbnail\', \'custom-fields\' ),
            \'taxonomies\' => array( \'\' ),
            //\'menu_icon\' => \'T\',
            \'menu_icon\' => plugins_url().\'/images/testimonial.png\',
            \'has_archive\' => true
        )
    );
}
endif;
