Switching languages

With multiple available languages you probably want to provide a way for your users to switch between those languages.

The $site->languages() method makes it easy to fetch all information about available languages. Here are two possible ways to implement such a language switch.

Switch A

The first option is to redirect users to the home page, when they select another language. This can be done by using $language->url() for the link.

<nav class="languages" role="navigation">
  <ul>
    <?php foreach($site->languages() as $language): ?>
    <li<?php e($site->language() == $language, ' class="active"') ?>>
      <a href="<?php echo $language->url() ?>">
        <?php echo html($language->name()) ?>
      </a>
    </li>
    <?php endforeach ?>
  </ul>
</nav>

Switch B

The second option is to redirect users to the same page in the selected language. This can be done by using $page->url($language->code()) for the link.

<nav class="languages" role="navigation">
  <ul>
    <?php foreach($site->languages() as $language): ?>
    <li<?php e($site->language() == $language, ' class="active"') ?>>
      <a href="<?php echo $page->url($language->code()) ?>">
        <?php echo html($language->name()) ?>
      </a>
    </li>
    <?php endforeach ?>
  </ul>
</nav>

PS…

You might have noticed the following in both switches:

<li<?php e($site->language() == $language, ' class="active"') ?>>

This line of code will check if the currently active language matches the one, which is just being returned in the loop.

$site->language() == $language

The e() helper is a Kirby shortcuts to a more complex way of writing an inline if clause:

<?php echo $site->language() == $language ? ' class="active"' : '' ?>

The entire code will attach class="active" to the list element if the languages match. This makes it possible to style the currently active language in a different way.

Switch C

You can use this third option if you want to redirect the user to the error page or any other page you define, e.g. home or search, in case there is no content available in the target language:

<nav class="languages" role="navigation'">
  <ul>
  <?php foreach($site->languages() as $language): ?>
        <li<?php e($site->language() == $language, ' class="active"') ?>>
          <a href="<?php e($page->content($language->code())->language() != $site->language($language->code()), page('error')->url($language->code()), $page->url($language->code()))?>"><?php echo $language->code(); ?></a> 
        </li> 
  <?php endforeach ?>
  </ul>
</nav>
