如何显示菜单树的一部分? [英] how to display part of a menu tree?

问题描述

我正在尝试处理Wordpress 3.0.这是一件很酷的事情，但我无法解决一个问题.例如，我有这样的菜单树.菜单树是由页面构成的.

I'm trying to deal with Wordpress 3.0. It's rather cool thing but I can't get on with one problem. For example, I have such menu tree. Menu tree is constructed from pages.

Home
   news
   video
   audio
Blog
   About author
   Favourite colors
      red
      blue
      green
My car
   wheels
   tires

这个想法是: 主菜单包含根元素:家庭，博客，我的车 在左侧，我想显示当前活动根元素的子元素.

The Idea is: main menu consists of root elements: home, blog, my car On the left side I would like to display children elements of current active root element.

例如，如果某人在主页"页面上，则在左侧应该看到:

For exammple if person is on the "home" page, on the left part he should see:

  news
  video
  audio

如果用户在博客"页面上，则应该看到:

If user is on the "Blog" page, he should see:

About author
       Favourite colors
          red
          blue
          green

我找不到执行此操作的API.你能给我点个手势吗?我在哪里可以找到它?

I can't find an API to do that. Can you sugest me please where can I find it?

UPD: @杰森·麦克雷里(Jason McCreary) 我已经看过wp_list_pages()并尝试过.我不知道如何使用它: 请，请参阅我的模板页面:

UPD: @Jason McCreary I've seen I've seen wp_list_pages() and tried it. I din't get how can I use it: Please, see my template for a page:

    <?php
/*
 Template Name: page_news

 * @package WordPress
 * @subpackage Twenty_Ten
 * @since Twenty Ten 1.0
 */

get_header(); ?>
<h1>page_news</h1>
<h1>Children menu:</h1>
<?php wp_list_pages('echo=0&child_of=8&title_li='); ?>
<div id="container">
        <div id="content" role="main">

        <?php
        /** Get category id by name*/
        //$catId = get_category_by_slug('news')->term_id;
        query_posts('category_name=news');
        get_template_part( 'loop', 'page' );
        ?>

        </div><!-- #content -->
</div><!-- #container -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

请参阅以下代码行:

<?php wp_list_pages('echo=0&child_of=8&title_li='); ?>

我确实有id = 8的页面(我在URL中看到它). id = 8的页面有多个子代. 我想打印它们，但不打印.函数 wp_list_pages()的输出为空. 我不知道为什么...:(

I do have the page with id=8 (I see it in URL). Page with id=8 has several children. I want to print them, but they are not printed. The output of the function wp_list_pages() is nothing. I don't know why... :(

推荐答案

我已经停止探索如何在服务器端输出worpress网站分类法的自定义部分.我只是使用jquery从主菜单复制活动分类分支并将其粘贴到我需要的页面容器中.

I've stopped to explore how to output custom part of worpress site taxonomy on the server-side. I just use jquery to copy active taxonomy branch from main menu and paste it to the page container I need.
