现在，我将向您介绍创建分类法的过程，以及创建的自定义分类法的特定类别的帖子分页时出现的错误。

Step 1: 注册自定义帖子类型

register_post_type(\'product\', [
    \'supports\' => [\'title\', \'editor\', \'meta\', \'excerpt\'],
    \'public\' => true,
    \'labels\' => [
        \'name\' => \'Products\',
        \'add_new_item\' => \'Add new product\',
        \'edit_item\' => \'Edit product\',
        \'all_items\' => \'All Products\',
        \'singular_name\' => \'Product\'
    ],
    \'menu_icon\' => \'dashicons-portfolio\'
]);

Step 2: 为注册分类product 岗位类型：

register_taxonomy(\'product_category\', \'product\', [
    \'hierarchical\' => true,
    \'label\' => \'Categories\',
    \'show_ui\' => true,
    \'show_admin_column\' => true,
    \'singular_name\' => \'Category\',
    \'rewrite\' => array(\'slug\' => \'product_category\'),
    \'query_var\' => true
]);

然后我创建了一个page template 使用名称shop_categories_page.php 显示创建的分类项目（类别）。我可以通过url查看所有类别：http://siteurl.com/categories

然后我创建了wordpress分类法模板，用于显示具有文件名的类别项目taxonomy-product_category.php<类别项目的hr>URL将为http://siteurl.com/product_category/itemname. 当我根据url中的当前项目对所有帖子分页时return error not found 404. 分页url将为http://siteurl.com/product_category/itemname/page/2. 你可以看到我的所有文件here<人力资源>How can be solved my problem with pagination?

$searchProductsByCategory = [
   \'posts_per_page\'      => 1,
   \'post_type\' => \'product\',
   \'ignore_sticky_posts\' => 1,
   \'orderby\'             => \'id\',
   \'tax_query\' => [
       [
           \'taxonomy\' => \'product_category\',
           \'terms\'    => get_queried_object_id()
       ]
   ]
];

$foundProducts = new WP_Query($searchProductsByCategory);

if ( have_posts() ) :
    while ( have_posts() ) : the_post();

    endwhile;
endif;
