参考链接了解您的知识Template Hiearchy 有关WordPress选择模板的详细信息

对于分类法中的分类术语slug（“运动”您的示例），WordPress将尝试使用以下模板（按此顺序）

taxonomy-{taxonomy}-{slug}.php
taxonomy-{taxonomy}.php
taxonomy.php
archive.php
index.php

修改下面的texonomy代码段：

function my_post_type() {    

    $args = array(
        \'labels\' => array(
            \'name\' => \'News\',
            \'singular_name\' => \'News\',
            \'add_new\' => \'Add New News\',
            \'add_new_item\' => \'Add New News\',
            \'edit_item\' => \'Edit News\',
            \'new_item\' => \'New News\',
            \'all_items\' => \'All News\',
            \'view_item\' => \'View News\',
            \'search_items\' => \'Search News\',
            \'not_found\' =>  \'No News Found\',
            \'not_found_in_trash\' => \'No News found in Trash\', 
            \'parent_item_colon\' => \'\',
            \'menu_name\' => \'News\',
        ),
        \'public\' => true,
        \'has_archive\' => true,
        \'menu_icon\' => \'dashicons-admin-site-alt3\',
        \'supports\' => array(\'title\',\'editor\',\'thumbnail\'),
        \'capability_type\' => \'post\',

    );   

    register_post_type(\'news\', $args);

}    
add_action(\'init\', \'my_post_type\');

function my_taxonomy() {
    $args = array(
        \'labels\' => array(
            \'name\' => \'News Category\',
            \'singular_name\' => \'News Category\',
        ),
        \'public\' => true,
        \'hierarchical\' => true,
    );

    register_taxonomy(\'news_cat\', array(\'news\'),$args);

}

add_action(\'init\', \'my_taxonomy\');

对于您的“体育”、“游戏”、“政治”分类术语页面，WordPress将使用

将此文件放在主题根目录中

taxonomy-news_cat-sports.php
taxonomy-news_cat-games.php
taxonomy-news_cat-politics.php

Permalinks您还指定了url重写，因此假设重写规则已刷新并且没有冲突，以下操作也应该可以

www.example.com/news_cat/games

注意：不要忘记更新永久链接，否则类别术语页面将重定向到404页面

taxonomy-news\\u cat-sports。php
