我想重写作者URL以使用作者ID来确定显示的是谁的页面，然后在作者ID之后自动添加用户名。
URL应忽略用户名，以防止用户名更改破坏旧的配置文件链接，但也应重定向到当前使用的用户名。
example.com/u/{user_id}/ -> example.com/u/{user_id}/{username}/
example.com/u/{user_id}/{anything}/ -> example.com/u/{user_id}/{username}/
到目前为止，我有一些允许URL浏览到作者页面的代码，但在URL中的ID之后添加任何内容时都不起作用。
// It works!
example.com/u/{user_id}/
// Works, but shouldn\'t work
example.com/u/{username}/
// Doesn\'t work...
example.com/u/{user_id}/{anything}/
这是我当前的代码。
add_action(\'init\',\'change_user_permalink\');
function change_user_permalink() {
global $wp_rewrite;
$wp_rewrite->author_base = \'u\';
$wp_rewrite->author_structure = \'/\' . $wp_rewrite->author_base . \'/%author%/\';
add_rewrite_rule(\'^u/([0-9]+)/?$\', \'index.php?author=$matches[1]\', \'top\');
}
