我已注册分类：

$taxonomySetup = [
    \'label\' => __(\'Products catalog\'),
    \'has_archive\' => false,
    \'hierarchical\' => true,
    \'rewrite\' => [
        \'slug\' => __(\'catalog\'),
        \'hierarchical\' => true,
        \'with_front\' => true
    ],
];
register_taxonomy(\'products\', [\'product\'], $taxonomySetup);


add_action(\'init\', \'addTaxonomiesToPages\');
function addTaxonomiesToPages() {
    register_taxonomy_for_object_type(\'products\', \'product\');
}

链接到CPT：

register_post_type(\'product\', [
    \'labels\' => [
        // labels definitions
    ],
    \'public\'                => true,
    \'has_archive\'           => true,
    \'menu_icon\'             => \'dashicons-archive\',
    \'show_in_nav_menus\'     => true,
    \'taxonomies\'            => [\'products\'],
    \'publicly_queryable\'    => false,
    \'rewrite\' => [
        \'pages\' => true,
    ],
    \'supports\' => [
        // supported items
    ],
]);

现在，我有了类别（对于此分类法）结构和结果：

• http://example.com/catalog - Not Found
• http://example.com/catalog/subcategory-1 - taxonomy.php
• http://example.com/catalog/subcategory-1/subcategory-2 - taxonomy.php
• http://example.com/catalog/subcategory-1/subcategory-2/subcategory-3 - taxonomy.php
• http://example.com/catalog/subcategory-1/subcategory-2/subcategory-3/subcategory-4 - taxonomy.php

我为它创建了许多文件：

• taxonomy.php
• taxonomy-products.php
• taxonomy-product.php
• taxonomy-catalog.php

为什么它总是加载基本分类法模板，而对于主目录，它总是呈现404 错误

顺便问一下，我如何控制应该为子类别加载哪个模板（我说的是子级别，而不是命名）？

if( subcat ){
 // show sub category view
}elseif(parent) {
 // show parent category view 
}
