Redirect New Registered Users to a Specific Page

If your site allows registration to your WordPress site, you may want to redirect new registrants to a specific page after successful registration. For example, a page where they can download a file, or one that shows important information you want that user to see after registration:

function sv_registration_redirect(){
    return home_url( '/finished/' );
}
add_filter( 'registration_redirect', 'sv_registration_redirect' );
