wordpress - 使用单个类别显示所有帖子和自定义帖子类型

Question

我用 CPT UI 创建了一个帖子类型:

add_action( 'init', 'cptui_register_my_cpts_matratze' );
function cptui_register_my_cpts_matratze() {
    $labels = array(
        "name" => __( 'Matratzen', '' ),
        "singular_name" => __( 'Matratze', '' ),
        );

    $args = array(
        "label" => __( 'Matratzen', '' ),
        "labels" => $labels,
        "description" => "",
        "public" => true,
        "publicly_queryable" => true,
        "show_ui" => true,
        "show_in_rest" => false,
        "rest_base" => "",
        "has_archive" => true,
        "show_in_menu" => true,
                "exclude_from_search" => false,
        "capability_type" => "post",
        "map_meta_cap" => true,
        "hierarchical" => false,
        "rewrite" => array( "slug" => "matratze", "with_front" => true ),
        "query_var" => true,

        "supports" => array( "title", "editor", "thumbnail", "excerpt", "trackbacks", "custom-fields", "comments", "revisions", "author", "page-attributes", "post-formats" ),      
        "taxonomies" => array( "category", "post_tag" ),
            );
    register_post_type( "matratze", $args );

// End of cptui_register_my_cpts_matratze()
}

但是，当我想通过前端中的链接访问类别时，我没有收到任何帖子。

例如，当你点击我什么也得不到:

Category

该帖子已发布，类别为 DaMi :

Post

是我的 CPT UI Post Type配置错误？任何建议我做错了什么？

默认情况下，您的 WordPress 网站上的类别页面将仅显示默认的“帖子”帖子类型，因此您需要在 Wordpress 通过添加 pre_get_posts 过滤器查询帖子之前添加您的 CPT。

在此处添加代码:

add_filter('pre_get_posts', 'query_post_type');
function query_post_type($query) {
  if( is_category() ) {
    $post_type = get_query_var('post_type');
    if($post_type)
        $post_type = $post_type;
    else
        $post_type = array('nav_menu_item', 'post', 'matratze'); // don't forget nav_menu_item to allow menus to work!
    $query->set('post_type',$post_type);
    return $query;
    }
}
