我一直在遵循answer here 它创造了奇迹。

但我的问题是在这方面，

在原件上：

add_filter(\'rewrite_rules_array\', \'mmp_rewrite_rules\');
function mmp_rewrite_rules($rules) {
    $newRules  = array();
    $newRules[\'custom-post-type-base/(.+)/(.+)/(.+)/(.+)/?$\'] = \'index.php?custom_post_type_name=$matches[4]\'; // my custom structure will always have the post name as the 5th uri segment
    $newRules[\'custom-post-type-base/(.+)/?$\']                = \'index.php?taxonomy_name=$matches[1]\'; 

    return array_merge($newRules, $rules);
} 

我的版本：

add_filter(\'rewrite_rules_array\', \'mmp_rewrite_rules\');
function mmp_rewrite_rules($rules) {
    $newRules  = array();
    $newRules[\'custom-post-type-base/(.+)/(.+)/(.+)/?$\'] = \'index.php?custom_post_type=$matches[3]\'; 
    $newRules[\'custom-post-type-base/(.+)/?$\']           = \'index.php?custom_taxonomy=$matches[1]\';

    return array_merge($newRules, $rules);
} 

由于我的分类法有两个级别，它无法识别第二个参数(custom-post-type-base/(.+)/[here]/) 是自定义帖子或自定义分类法。。它在自定义分类法上正确返回，但在自定义帖子类型上返回404，帖子类型在父分类法上分类。

请参见示例URL：

"/custom-post-type-base/taxonomy-parent/taxonomy-child/single-custom-post-type/"
/*works as single custom post*/

"/custom-post-type-base/taxonomy-parent/taxonomy-child/"
/*works as custom taxonomy page*/

"/custom-post-type-base/taxonomy-parent/"
/*works as custom taxonomy page too*/

"/custom-post-type-base/taxonomy-parent/single-custom-post-type/"
/*returns a 404*/

$newRules[\'basename/(.+)/(.+)/(.+)/(.+)/?$\'] = \'index.php?custom_post_type_name=$matches[4]\'; // my custom structure will always have the post name as the 5th uri segment
