How to get absolute url with different domain language prefix

Question

What is the best way to get absolute url with correct language prefix? The url() function accepts language parameter but it seems that it is not using it to generate the prefix - only to get translated alias. I don't care about aliases - I need correct domain prefix.

When I'm on http://en.example.com/something and use this code:

<?php
$all_languages = language_list();
url('something-else', array('language' => $all_languages['nl'], 'absolute' => true));
?>

I will get this: http://en.example.com/something-else (en prefix).

How can I get this: http://nl.example.com/something-else (nl prefix).

This was pulled from my theme file, but as long as you have access to $node and $language, it will do the trick:

<?php
    if (isset($node))
    {
?>
<div class="language-switcher">
        <?php
            $nodes = translation_path_get_translations("node/" . $node->nid);
            $path  = "";
            if ($language->language == "en")
            {
                if (array_key_exists("nl", $nodes))
                {
                    $path = drupal_get_path_alias($nodes["nl"], "nl");
                }
        ?>
        <a href="http://nl.example.com/<?php print $path; ?>">Change to NL</a>
        <?php
            }
            else
            {
                if (array_key_exists("en", $nodes))
                {
                    $path = drupal_get_path_alias($nodes["en"], "en");
                }
        ?>
        <a href="http://en.example.com/<?php print $path; ?>">Change to EN</a>
        <?php
            }
        ?>
</div>
<?php
    }
?>

The URL's are hard coded with the path information calculated.

Answer 2

Apparently the url() function will create links like http://nl.example.com/something-else (note the nb prefix) BUT only for specific languages configuration. This will work correctly only if I set appropriate domain for each language here: /admin/config/regional/language.

By default the field Path prefix language code is set to language code (nl in this case) and Language domain is empty.

Now since I am using DOMAIN prefix for language selection, and not the PATH prefix, then for each language I should set language domain instead of path prefix.

For some weired reason Drupal insists on filling only one of those fields, but consequently fills Path prefix language code by default even if language detection is set to domain.

I format my urls like this.

 $order_url = url('user/' . $params['order']->uid . '/orders/'. $params['order']->order_id, array(
'absolute' => TRUE, 
'language' => (object)array(
  'language' => 'lang-key',
)
  ));

We can see this is reflected in the url function below.

$language = isset($options['language']) && isset($options['language']->language) ? $options['language']->language : '';
$alias = drupal_get_path_alias($original_path, $language);
if ($alias != $original_path) {
  $path = $alias;
}


}
