title: appending query string while rendering a twig template
body: <p>I'm currently working on a simple application using Twig as a template engine. My problem is that I cannot append a query string like <code>?id=15</code> while rendering a template (which I can do on a simple redirect) like this:</p>
  
  <pre><code>if($booking){
          // render template
          View::renderTemplate('admin/bookings/check_booking.html', ['booking' =&gt; $booking]);
      } else {
          self::redirect('/admin/bookings/book-room?id='. $booking-&gt;room_id);
      }
  </code></pre>
  
  <p>I don't use any framework like Symfony or others. Is there any way around this problem?</p>
