wordpress page template redirect

I was doing some research on wordpress tags and categories and the below script which is needed for redirecting single posts related categoies and tags to be redirected to the post itself in wordpress. Below code is wordpress redirect without plugin needed. it does not add more overhead on server performance.

Below code can be added to child theme(recommended) or to your theme’s functions.php file

function redirect_to_post(){
global $wp_query;
if( is_archive() && $wp_query->post_count == 1 ){
the_post();
$post_url = get_permalink();
wp_redirect( $post_url );
}

} add_action(‘template_redirect’, ‘redirect_to_post’);
