Wordpress Author Permalinks -

i know how change base of author permalinks, on site, refer users not username number based on user id, user number 5 wrote post, rather johndoe123 wrote post.

the problem comes when go users archives , instead of seeing example.com/authors/5/ see example.com/authors/johndoe123/ .

how change permalinks can pull author archives using following structure? :

[wordpress_site_url]/authors/[user_id]/

this can done adding new rewrite rules each user in same way when changing or removing author base. so, adapting code previous answer, add rewrite rules this:

add_filter('author_rewrite_rules', 'my_author_url_with_id_rewrite_rules'); function my_author_url_with_id_rewrite_rules($author_rewrite) {   global $wpdb;   $author_rewrite = array();   $authors = $wpdb->get_results("select id, user_nicename nicename {$wpdb->users}");       foreach ($authors $author) {     $author_rewrite["authors/{$author->id}/page/?([0-9]+)/?$"] = 'index.php?author_name=' . $author->nicename . '&paged=$matches[1]';     $author_rewrite["authors/{$author->id}/?$"] = "index.php?author_name={$author->nicename}";   }   return $author_rewrite; } 

and filter author link:

add_filter('author_link', 'my_author_url_with_id', 1000, 2); function my_author_url_with_id($link, $author_id) {   $link_base = trailingslashit(get_option('home'));   $link = "authors/$author_id";   return $link_base . $link; }

actually don't think need create rules each user in case, following 2 rules should suffice:

add_filter('author_rewrite_rules', 'my_author_url_with_id_rewrite_rules'); function my_author_url_with_id_rewrite_rules($author_rewrite) {   $author_rewrite = array();   $author_rewrite["authors/([0-9]+)/page/?([0-9]+)/?$"] = 'index.php?author=$matches[1]&paged=$matches[2]';   $author_rewrite["authors/([0-9]+)/?$"] = 'index.php?author=$matches[1]';   return $author_rewrite; }
