我创建了三个插件，它们定义了自定义帖子类型并使用template_include 要包括单帖子版本的模板。

出于某种原因，我构建的最新版本正确地创建了记录，但似乎找不到模板。代码实际上是复制和粘贴的，所以我不知道为什么会这样。唯一的更改是函数名和post类型，以避免冲突。

下面是添加template_include 过滤器：

function include_person_template_function($template_path)
{
    if (get_post_type() == \'featured_people\') {
        if (is_single()) {
            if ($theme_file = locate_template(\'single-featured-person.php\')) {
                $template_path = $theme_file;
            } else {
                $template_path = plugin_dir_path(__FILE__) . \'single-featured-person.php\';
            }
        }
    }
    return $template_path;
}

add_filter(\'template_include\', \'include_person_template_function\', 1);

由于管理员工作正常，因此唯一可能出现问题的其他部分是在何处定义了帖子类型：

function create_featured_people()
{
    register_post_type(\'featured_people\', array(
    \'labels\' => array(
      \'name\' => \'Featured People\',
      \'singular_name\' => \'Featured Person\',
      \'add_new\' => \'Add New\',
      \'add_new_item\' => \'Add New Featured Person\',
      \'edit\' => \'Edit\',
      \'edit_item\' => \'Edit Featured Person\',
      \'new_item\' => \'New Featured Person\',
      \'view\' => \'View\',
      \'view_item\' => \'Featured Person\',
      \'search_items\' => \'Search Featured People\',
      \'not_found\' => \'No Featured People Found\',
      \'not_found_in_trash\' => \'No Featured People Found in Trash\',
      \'parent\' => \'Parent Featured Person\'
    ),
    \'public\' => true,
    \'menu_position\' => 15,
    \'supports\' => array( \'title\', \'editor\', \'thumbnail\' ),
    \'taxonomies\' => array( \'\' ),
    \'has_archive\' => true
  ));
}
