在你的分类法上，我不得不删除功能，因为它没有显示在我的菜单上，如果它对你有用，请忽略它，但我看不到它的任何用例。

您的重写是问题所在，您可以使用post_type_link:

add_filter(\'post_type_link\', \'so_update_permalink_structure\', 10, 2);

function so_update_permalink_structure( $post_link, $post )
{
    if ( false !== strpos( $post_link, \'%community_post_domain%\' ) ) {
        $taxonomy_terms = get_the_terms( $post->ID, \'community_post_domain\' );
        foreach ( $taxonomy_terms as $term ) {
            if ( ! $term->parent ) {
                $post_link = str_replace( \'%community_post_domain%\', $term->slug, $post_link );
            }
        }
    }
    return $post_link;
}

通过快速搜索，我找到了一篇解释得比我好得多的博客文章，它对您的案例很有用：https://react2wp.com/using-same-slug-for-custom-post-type-and-custom-taxonomy/

edit: 我的permalinks测试：

// Created a page with the same slug
// Test url: ok
url.test/community/

// Created the taxonomy \'kubernetes\'
// Test url: ok
url.test/community/kubernetes/

// Created a new cpt post
// Post with a taxonomy: ok
url.test/community/kubernetes/go-micro-services/

// Post without a taxonomy: error 400
// For this case you should set a default taxonomy to prevent an error
url.test/community/%community_post_domain%/go-micro-services/
