我用php创建了一个自定义的帖子类型，我的问题是这个帖子类型没有出现在Toolset Types插件的菜单中。我想这一定是我必须要做的选择，但我几乎每件事都试过了，我不知道为什么会这样。

我想编辑帖子类型之间的关系，特别是汽车和新闻之间的关系。

我创建自定义帖子类型的代码如下。

function car_post_type() {
    $labels = array(
        \'name\' => \'Coches\',
        \'singular_name\' => \'Coche\',
        \'menu_name\' => \'Coches\',
        \'name_admin_bar\' => \'Coches\',
        \'parent_item_colon\' => \'Padre:\',
        \'all_items\' => \'Todos los coches\',
        \'add_new_item\' => \'Añadir nuevo coche\',
        \'add_new\' => \'Añadir coche\',
        \'new_item\' => \'Nuevo coche\',
        \'edit_item\' => \'Editar coche\',
        \'update_item\' => \'Actualizar coche\',
        \'view_item\' => \'Ver coche\',
        \'search_items\' => \'Buscar coches\',
        \'not_found\' => \'No hay resultados\',
        \'not_found_in_trash\' => \'No se han encontrado coches en la papelera\',
    );
    $rewrite = array(
        \'slug\' => \'coche\',
        \'with_front\' => true,
        \'pages\' => true,
        \'feeds\' => true,
    );
    $args = array(
        \'label\' => __( \'Car\', \'clever\' ),
        \'description\' => __( \'Cars\', \'clever\' ),
        \'labels\' => $labels,
        \'supports\' => array(
            \'title\', \'editor\', \'excerpt\', \'thumbnail\', \'revisions\',
        ),
        \'taxonomies\' => array(),
        \'hierarchical\' => false,
        \'public\' => true,
        \'show_ui\' => true,
        \'show_in_menu\' => true,
        \'menu_position\' => 5,
        \'menu_icon\' => \'dashicons-dashboard\',
        \'show_in_admin_bar\' => true,
        \'show_in_nav_menus\' => true,
        \'can_export\' => true,
        \'has_archive\' => true,
        \'exclude_from_search\' => false,
        \'publicly_queryable\' => true,
        \'rewrite\' => $rewrite,
        \'capability_type\' => \'post\',
    );

    register_post_type(\'car\', $args);
}
add_action(\'init\', \'car_post_type\', 0);
