WordPress的單一自定義帖子類型頁面不工作

Question

我創建了一個自定義帖子類型名稱狗食測驗作爲一個WordPress插件。帖子類型顯示，但是當我創建single-dog-food-quiz.php文件時，頁面不顯示任何內容。這裏是我的代碼：

對於狗食品quiz.php：

function dog_food_quiz() { 
    register_post_type('dog-food-quizzes', 
     array(
     'labels' => array(
      'name' => 'Dog Food Quiz', 
      'singular_name' => 'Dog Food Quiz', 
      'add_new' => 'Add New', 
      'add_new_item' => 'Add New Dog Food Quiz', 
      'edit' => 'Edit', 
      'edit_item' => 'Edit Dog Food Quiz', 
      'new_item' => 'New Dog Food Quiz', 
      'view' => 'View', 
      'view_item' => 'View Dog Food Quiz', 
      'search_items' => 'Search Dog Food Quizzes', 
      'not_found' => 'No Dog Food Quizzes found', 
      'not_found_in_trash' => 'No Dog Food Quizzes found in Trash', 
      'parent' => 'Parent Dog Food Quiz' 
     ), 

     'public' => true, 
     'menu_position' => 15, 
     'supports' => array('title', 'editor', 'comments', 'thumbnail', 'custom-fields'), 
     'taxonomies' => array(''), 
     'menu_icon' => 'dashicons-testimonial', 
     'has_archive' => true 
    ) 
); 
} 

add_action('init', 'dog_food_quiz'); 

add_filter('template_include', 'include_template_function', 1); 

function include_template_function($template_path) { 
    if (get_post_type() == 'dog_food_quizzes') { 
     if (is_single()) { 
     // checks if the file exists in the theme first, 
     // otherwise serve the file from the plugin 
     if ($theme_file = locate_template(array ('single-dog-food-quiz.php'))) { 
      $template_path = $theme_file; 
     } else { 
      $template_path = plugin_dir_path(__FILE__) . '/single-dog-food-quiz.php'; 
     } 
    } 
} 
    return $template_path; 
} 

這裏是單狗食品quiz.php代碼：

      </div> 
     </aside> 
    </div> 
    </main> 

    <?php endwhile; ?> 

    <?php get_footer(); ?> 

我錯過這裏有什麼？ 我得到的只是頁眉和頁腳以及一個空白頁面。請幫忙。

Answer 1

您可能想嘗試將模板重命名爲single-dog-food-quizzes.php（即，將single-與您註冊的自定義帖子類型的名稱dog-food-quizzes相加）。

另外值得一提的是，在註冊由多個單詞組成的自定義帖子類型時，最好使用下劃線而不是連字符。所以你的情況： 狗食品測驗（單數）

然後你寫單：

register_post_type('dog_food_quizzes')

Answer 2

這可能，如果你的名字你自定義後類型（CPT）這樣會更好dog-food-quiz.php文件在你的主題中。

For Custom Post Types, should the slug be singular or plural?
