我需要有关如何在WordPress本机小部件和主题小部件的类别下拉选项列表中为“视频”CPT创建自定义分类或类别的帮助。我得到的唯一类别是默认帖子。

任何帮助都将不胜感激。我对php不太熟悉。

更多详细信息。

主题是：封面新闻

我的自定义帖子类型

现在，我需要帮助来修改小部件的代码，以便在下拉列表中包含自定义帖子类型类别。

这是主题小部件代码：

    {
    /**
     * Sets up a new widget instance.
     *
     * @since 1.0.0
     */
    function __construct()
    {
        $this->text_fields = array(\'covernews-posts-slider-title\');
        $this->select_fields = array(\'covernews-select-category\');

        $widget_ops = array(
            \'classname\' => \'covernews_posts_slider_widget\',
            \'description\' => __(\'Displays posts slider from selected category.\', \'covernews\'),
            \'customize_selective_refresh\' => true,
        );

        parent::__construct(\'covernews_posts_slider\', __(\'CoverNews Posts Slider\', \'covernews\'), $widget_ops);
    }

    /**

    public function widget($args, $instance)
    {
