自定义帖子Wordpress-Public布尔值

Question

我们有一个自定义帖子类型（在本例中称为“item”），我们只希望为网站成员提供这些类型。我们将布尔值“public”从“true”更改为“false”，但这会使自定义帖子甚至对用户不可用。有没有选项让自定义帖子仅供会员使用？

    register_post_type('item', Array(
        'public'                => true,
        'menu_icon'             => '',
        'labels'                => $labels,
        'supports'              => Array(
            'title', 'editor', 'thumbnail',
        ), 'rewrite'            => array('slug' => $javo_item_slug , 'with_front' => false )
        , 'query_var'           => true
        , 'taxonomies'          => Array( 'post_tag')
    ));
        // item > Category
        register_taxonomy('item_category', 'item', Array(
            'label'             => __( 'Item Category', "javo_fr" )
            , 'labels'          => Array(

            )

        // item > location
