Generate equivalent URL in other languages when tokens are present

That's because you're calling the alias() method with the 2nd parameter not set, which is the same as passing the current route parameters.

You need somehow to pass the localized parameters to the function.

One way of doing it is to create a template filter which localizes the parameter before calling the alias() method.

E.g:

// index.php or bootstrap file or controller hook method
$tpl = Template::instance();
$tpl->filter('url', function($name, $params=NULL, $lang=NULL) use($f3, $ml, $db) {
  $params += $f3->PARAMS;
  // your custom params localization here:
  switch ($name) {
    case 'gamessection':
      // localize the term contained in $params['section'] from $ml->current to $lang
      // e.g:
      $sql = 'SELECT target.slug FROM sections source LEFT JOIN sections target
              ON source.id=target.id WHERE source.slug=?
              AND source.lang=? AND target.lang=?';
      if ($res=$db->exec($sql, [1=>$params['section'], $ml->current, $lang])
        $params['section'] = $res[0]['slug'];
      break;
    // etc.
  }
  // end of custom localization
  return $f3->BASE . $ml->alias($name, $params, $lang);
});

<!-- template file -->
<a title="GamesSite - English" href="{{ @ALIAS, null, 'en' | url }}">English</a>

Thanks for your detailed answer. I'd left the 2nd parameter as null because I had no way to fill it in correctly as yet. I'll look into making a custom filter as you suggest.

Cheers
