我已经为此挣扎了几个小时了。

我正在尝试获取此URL结构：
example.com/business/%custom-tax-name%/%custom-post-name%/
我所说的海关税名称不是指分类法的名称（“位置”），而是指为特定职位选择的值，即城市名称。所以，
example.com/business/long-island-city/business-name
或
example.com/business/phoenix/business-name/

到目前为止，我已经制定了自定义分类法：

$singular = \'Merchant Location\';
$plural = \'Merchant Locations\';
$taxonomy_args = array(
    \'rewrite\' => array(
        \'slug\' => \'business-location\',
        \'with_front\' => FALSE,
        \'hierarchical\' => FALSE
    )
);  
// Register taxonomy ...

并更改了post_type_link 滤器

function filter_business_permalinks($post_link, $post, $leavename, $sample) {

if ($post->post_type == \'my_custom_post_type\') {
    $terms = get_the_terms($post->ID, \'my_custom_taxonomy\');
     foreach ($terms as $term) {
         $post_link = str_replace(\'business/\', \'business/\'. $term->slug .\'/\', $post_link);
         break;
     }

return $post_link;
}
add_filter(\'post_type_link\', \'filter_business_permalinks\', 10, 4);

在那之后，得到的URL很好，这正是我想要的，所以过滤器功能工作得很好。但是，当我单击URL时，它会转到以下位置：
example.com/business/long-island-city/long-island-city/business-name
生成404。

这可能是什么原因造成的，我如何修复它？

非常感谢您的帮助。

Note:
我不想要这样的URL结构：
example.com/business/location/long-island-city/business-name/
在URL中具有分类名称。

register_taxonomy(
    \'location\',
    array( \'business\' ),
    array(
        \'rewrite\' => array( \'slug\' => \'business-location\' )
    )
);

register_post_type(
    \'business\',
    array(
        \'label\' => \'Business\',
        \'public\' => true,
        \'rewrite\' => array( \'slug\' => \'business/%location%\' ),
        \'hierarchical\' => false
    )
);

function wpa_business_permalinks( $post_link, $id = 0 ){
    $post = get_post($id);
    if ( is_object( $post ) && $post->post_type == \'business\' ){
        $terms = wp_get_object_terms( $post->ID, \'location\' );
        if( $terms ){
            return str_replace( \'%location%\' , $terms[0]->slug , $post_link );
        }
    }
    return $post_link;
}
add_filter( \'post_type_link\', \'wpa_business_permalinks\', 1, 2 );
