Custom Post Type in Author Results

One thing I found was the default author page only showed posts by the author. This allows you to modify what post types show on the authors page. In this example it is showing this sites author page query.

if ( !function_exists('post_types_author_archives') ) {
    function post_types_author_archives($query) {
        if ($query->is_author)
                // Add 'code-snippet' CPT and the default 'posts' to display in author's archive
                $query->set( 'post_type', array('code-snippet', 'posts') );
        remove_action( 'pre_get_posts', 'custom_post_author_archive' );
    }
    add_action('pre_get_posts', 'post_types_author_archives');
}
