Examples

#1 Change the author archive page link

By default, WordPress generates the following author archive page link:

http://wp-test.ru/author/campusboy

Suppose you decide to display the author's posts at:

http://wp-test.ru/writer/campusboy

The following code creates such a link:

add_filter( 'author_link', 'filter_author_link', 10, 3 );

function filter_author_link( $link, $author_id, $author_nicename ) {
	return home_url( '/writer/' ) . $author_nicename;
}

However, visiting this page now results in a 404 error because WordPress does not know about this link structure. Tell it about the structure:

add_action( 'init', 'new_author_base' );
function new_author_base() {
	global $wp_rewrite;
	$wp_rewrite->author_base = 'writer';
}

After adding the code, flush the rewrite rules. To do this, simply visit the Permalinks page in the admin area.
