php - 如何将自定义帖子类型类别分开以发布类别

Question

我试图将特定帖子类型“公告”的类别列表与帖子类别分开。

我希望我的公告帖子类型有自己的类别列表，而不是与帖子类别列表混合

这是我的代码

function announcement_post_types() {
    register_post_type(
        'announcement',
        array(
            'labels' => array(
                'name' => __( 'Announcements' ),
                'singular_name' => __( 'announcement' ),
                'menu_name' => __( 'Announcements' ),
                'all_items' => __( 'All Announcements' ),
                'view_item' => __( 'View Announcement' ),
                'add_new_item' => __( 'New Announcement' ),
                'add_new' => __( 'New Announcement' ),
                'edit_item' => __( 'Edit Announcements' ),
                'update_item' => __( 'Update' ),
                'search_items' => __( 'Search' ),
                'not_found' => __( 'Not Found' ),
                'not_found_in_trash' => __( 'Not Found in Trash' ),
            ),
            'public' => true,
            'has_archive' => false,
            'rewrite' => array('slug' => 'announcement'),
            'menu_icon' => 'dashicons-admin-page',
            'supports' => array('title', 'editor', 'custom-fields')
        )
    );
    register_taxonomy(  
    'announcement_type',  
    'announcement',  // this is the custom post type(s) I want to use this taxonomy for
        array(  
            'hierarchical' => false,  
            'label' => 'News Types',  
            'query_var' => true,  
            'rewrite' => true  
        )  
    );  
    register_taxonomy_for_object_type('category', 'announcement');
}
add_action('init', 'announcement_post_types');

如果此代码有效，则将常规类别链接到公告帖子类型:

register_taxonomy_for_object_type('category', 'announcement');

我们需要将其与您创建并注册的新分类进行交换，因此将其交换为:

register_taxonomy_for_object_type('announcement_type', 'announcement');

如果这对您有用，请告诉我，这里可能还有更多问题，但这可能也足够了。
