從自定義帖子類型類別列出帖子？

Question

我有一個自定義職位類型，這樣創造了投資組合的分類：

$args = array(
     'label' => __('Portfolio', 'my-portfolio'), 
     'labels' => array(
      'add_new_item' => __('New portfolio', 'my-portfolio'), 
      'new_item' => __('New portfolio', 'my-portfolio'), 
      'not_found' => __('No portfolio items', 'my-portfolio'), 
     ), 
     'singular_label' => __('Portfolio', 'my-portfolio'), 
     'menu_icon' => 'dashicons-portfolio', 
     'public' => true, 
     'show_ui' => true, 
     'capability_type' => 'post', 
     'hierarchical' => true, 
     'has_archive' => true, 
     'exclude_from_search' => true, 
     'show_in_nav_menus' => false, 
     'supports' => array('title', 'editor', 'thumbnail'), 
     'rewrite' => array('slug' => 'portfolio', 'with_front' => false), 
     'register_meta_box_cb' => 'add_remove_metaboxes_portfolio', 
     ); 

    //Register type and custom taxonomy for type. 
    register_post_type('portfolio' , $args); 
    register_taxonomy("portfolio-category", array("portfolio"), array("hierarchical" => true, "label" => "Categories", "singular_label" => "Category", "rewrite" => true, "slug" => 'portfolio-category',"show_in_nav_menus"=>false)); 

這就像它應該當我使用它在我的查詢。並且它顯示在後端的菜單中，以及這個自定義帖子類型的類別。

我的問題是，當我嘗試從某個類別中檢索所有帖子時（通過點擊類別名稱），我在我的頁面上獲得No posts were found. Sorry!。

該頁面是一個默認的wordpress存檔，應該只列出所有帖子，但沒有任何顯示。網址是這樣的：

http://xampp/my-theme/?portfolio-category=animals

但是即使我使用名稱後的永久鏈接沒有任何作品。

我讀過CSS Tricks，我可以在functions.php

function namespace_add_custom_types($query) { 
    if(is_category() || is_tag() && empty($query->query_vars['suppress_filters'])) { 
    $query->set('post_type', array(
    'post', 'portfolio', 'nav_menu_item' 
     )); 
     return $query; 
    } 
} 
add_filter('pre_get_posts', 'namespace_add_custom_types'); 

使用此功能，但是這並沒有幫助。我在這裏錯過了什麼？

您必須爲自定義帖子類型使用存檔頁面模板。並請將代碼置於自定義帖子類型

$args = array(
     'label' => __('Portfolio', 'my-portfolio'), 
     'labels' => array(
      'add_new_item' => __('New portfolio', 'my-portfolio'), 
      'new_item' => __('New portfolio', 'my-portfolio'), 
      'not_found' => __('No portfolio items', 'my-portfolio'), 
     ), 
     'singular_label' => __('Portfolio', 'my-portfolio'), 
     'menu_icon' => 'dashicons-portfolio', 
     'public' => true, 
     'show_ui' => true, 
     'capability_type' => 'post', 
     'hierarchical' => true, 
     'has_archive' => true, 
     'exclude_from_search' => true, 
     'show_in_nav_menus' => false, 
     'supports' => array('title', 'editor', 'thumbnail'), 
     'rewrite' => array('slug' => 'portfolio', 'with_front' => false), 
     'register_meta_box_cb' => 'add_remove_metaboxes_portfolio', 
     ); 

    //Register type and custom taxonomy for type. 
    register_post_type('portfolio' , $args); 
flush_rewrite_rules();
