Add custom post types to author archives in WordPress

post_types_author_archives()

function post_types_author_archives($query) {
	
	// Add 'videos' post type to author archives
	if ( $query->is_author )
		$query->set( 'post_type', array('videos', 'post') );
	
	// Remove the action after it's run
	remove_action( 'pre_get_posts', 'post_types_author_archives' );
}
add_action( 'pre_get_posts', 'post_types_author_archives' );

No need to use remove_action here ;)
