i want active in navbar when page changes, how can it

you can that:

in index.php

switch($page){     case 'home':         echo $twig->render('home.twig', ['current' => 'home']);         break;     case 'iletisim':         echo $twig->render('iletisim.twig', ['current' => 'iletisim']);         break;     case 'hakkimizda':         echo $twig->render('hakkimizda.twig', ['current' => 'hakkimizda']);     .... 

and in layout.twig

<nav id="primary-menu" class="serif normal">     <ul>         <li {{ (current == 'home') ? 'class="current"' : '' }}><a href="index.php?p=home"><div>ana sayfa</div></a></li>               <li {{ (current == 'hakkimizda') ? 'class="current"' : '' }}><a href="index.php?p=hakkimizda"><div>hakkımızda</div></a></li>                              <li {{ (current == 'konaklama') ? 'class="current"' : '' }}><a href="index.php?p=konaklama"><div>konaklama</div></a></li>                             ... 

of course, improve way.
