我有一个自定义的帖子类型：

function thfo_register_cantine() {
    $labels = array(
        \'name\'               => \'Cantines\',
        \'singular_name\'      => \'Cantine\',
        \'menu_name\'          => \'Cantine\',
        \'all_items\'          => \'Tous les Menus\',
        \'add_new\'            => \'Ajouter un menu\',
        \'add_new_item\'       => \'Ajouter un menu\',
        \'edit\'               => \'Modifier\',
        \'edit_item\'          => \'Modifier le menu\',
        \'new_item\'           => \'Nouveau menu\',
        \'view\'               => \'Voir\',
        \'view_item\'          => \'Voir le menu\',
        \'search_items\'       => \'Chercher un menu\',
        \'not_found\'          => \'Rien de trouver\',
        \'not_found_in_trash\' => \'Non trouvé dans la corbeille\',
    );

    $args = array(
        \'labels\'              => $labels,
        \'description\'         => \'\',
        \'public\'              => true,
        \'show_ui\'             => true,
        \'has_archive\'         => true,
        \'show_in_menu\'        => true,
        \'exclude_from_search\' => false,
        \'capability_type\'     => \'post\',
        \'map_meta_cap\'        => true,
        \'hierarchical\'        => false,
        \'rewrite\'             => array( \'slug\' => \'cantine\', \'with_front\' => true ),
        \'query_var\'           => true,
        \'supports\'            => array( \'title\' ),
        \'show_in_rest\'        => true,
        \'publicly_queryable\'  => true,
        \'show_in_admin_bar\'   => true,
        \'show_in_menu\'        => true,
        \'show_in_admin_menu\'  => true,
        \'show_in_nav_menus\'   => true,
        \'can_export\'          => true,
    );
    register_post_type( \'cantine\', $args );
}

在上front-page.php, 如果我问

get_posts( array(\'post_type\' => array( \'cantine\' ),\'posts_per_page\' => 2,));

我有两篇帖子，但如果我问get_posts( array( \'post__in\' => $ids, \'posts_per_page\' => 5 ) );哪里$ids 是一个带有我的CPT ID的数组，那么，我没有任何结果。。。

你知道为什么吗？

非常感谢

$actus_new = get_posts( array(
    \'post_type\'      => array( \'cantine\', \'post\' ),
    \'post__in\'       => $ids,
    \'posts_per_page\' => 5,
) );
