我有一个自定义的帖子类型，叫做cars。品牌有一个分类法。

我有一个模板的单车。php和我想添加一个链接到品牌页面（类别）。假设我在2013年帕萨特赛后的页面上。品牌为大众。我想展示大众品牌的永久魅力。

我的设置：功能。php

$labelsCars = array(
    \'name\' => \'Cars\',
    \'singular_name\' => \'Car\',
    \'menu_name\' => \'Cars\',
    \'add_new_item\' => \'Add New Car\',
    \'edit_item\' => \'Edit Car\',
    \'new_item\' => \'New Car\',
    \'view_item\' => \'View Car\',
    \'not_found\' => \'No Cars Found\'
);

$argsCars = array(
  \'labels\' => $labelsCars,
  \'public\' => true,
  \'publicly_queryable\' => true,
  \'show_ui\' => true, 
  \'show_in_menu\' => true, 
  \'query_var\' => true,
  \'rewrite\' => true,
  \'capability_type\' => \'post\',
  \'has_archive\' => true, 
  \'hierarchical\' => false,
  \'menu_position\' => null,
  \'supports\' => array(\'title\',\'editor\',\'page-attributes\',\'thumbnail\'),
  \'exclude_from_search\' => true,
  \'taxonomies\' => array(\'brands\')
); 
register_post_type(\'cars\',$argsCars);

$labels = array(
  \'name\' => \'Brands\',
  \'singular_name\' => \'Brand\',
  \'search_items\' => \'Search Brands\',
  \'all_items\' => \'All Brands\',
  \'edit_item\' => \'Edit Brand\', 
  \'update_item\' => \'Update Brand\',
  \'add_new_item\' => \'Add New Brand\',
  \'new_item_name\' => \'New Brand\',
  \'menu_name\' => \'Brands\'
);  

register_taxonomy(\'brands\',array(\'cars\'), array(
   \'labels\' => $labels, 
   \'hierarchical\' => true,
   \'show_ui\' => true,
   \'query_var\' => true,
   \'rewrite\' => array( \'slug\' => \'brands\' ),
   \'show_in_nav_menus\' => true
 ));

<?php get_header(); ?>
<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
<?php $content = get_the_excerpt(); ?>
<?php the_content() ?>
<?php echo \'<pre>\'.print_r(get_the_category($post->ID), 1).\'</pre>\'; ?>
<?php endwhile; // end of the loop. ?>
<?php get_footer(); ?>

我一直在用谷歌搜索文档，当然也在这里，但我什么也没找到。。

我应该怎么做才能解决这个问题？
