Wordpress custom author urls - wordpress

Question

I want to implement custom author urls.
Currently the author urls are like this:
http://site.com/author/author-name/
I want to do something like
http://site.com/my-custom-url-here
For each individual user.
I have tried using author_rewrite_rules filter, using the following code, this converts the url correctly but this gives me a page not found message when i browse the url
add_filter('author_link', 'no_author_base', 1000, 3);
function no_author_base($link, $author_id) {
$link_base = trailingslashit(get_option('home'));
$link = preg_replace("|^{$link_base}author/|", '', $link);
return $link_base . $link;
}
add_filter('author_rewrite_rules', 'no_author_base_rewrite_rules');
function no_author_base_rewrite_rules($author_rewrite) {
global $wpdb;
$author_rewrite = array();
$authors = $wpdb->get_results("SELECT user_nicename AS nicename from $wpdb->users");
foreach($authors as $author) {
$author_rewrite["({$author->nicename})/page/?([0-9]+)/?$"] = 'index.php?author_name=$matches[1]&paged=$matches[2]';
$author_rewrite["({$author->nicename})/?$"] = 'index.php?author_name=$matches[1]';
}
return $author_rewrite;
}
Any help would be greatly appreciated!
Thanks.
UPDATE
Problem is solved!, basically i did not know about calling the flush_rewrite_rules function.

Answer 1

Solved!
Here's how i did it:
i did not need the author_link filter so i removed it, my custom urls are stored in usermeta table so i fetched them and passed them into the rewrite array, and most importantly I DID NOT KNOW ABOUT FLUSHING THE REWRITE CACHE AND THAT WAS THE REASON MY ORIGINAL CODE WAS NOT WORKING
Heres the full code:
add_filter('author_rewrite_rules', 'my_author_url_with_custom_url_rewrite_rules');
function my_author_url_with_custom_url_rewrite_rules($author_rewrite) {
global $wpdb;
$author_rewrite = array();
$authors = $wpdb->get_results("SELECT ID, user_nicename AS nicename, meta_value as profile_name
from $wpdb->users
LEFT JOIN wp_usermeta ON wp_usermeta.user_id = $wpdb->users.ID
WHERE meta_key = 'profile_name'");
foreach ($authors as $author) {
$author_rewrite["{$author->profile_name}/page/?([0-9]+)/?$"] = 'index.php?author_name=' . $author->nicename . '&paged=$matches[1]';
$author_rewrite["{$author->profile_name}/?$"] = "index.php?author_name={$author->nicename}";
}
return $author_rewrite;
}
flush_rewrite_rules(false);
dont forget to comment the flush_rewrite_rules call after you are done with rewrite rules, it is very expensive!

try this one. for get your author url.
<?php the_author_posts_link(); ?>
if post a admin or a author and want to show his/her all post in one page. so, you need to get his/her url automatic. then try this one
