How can I change the preferred language when clicking in an anchor link (Kohana's i18n)?

Question

I have a es.php and a tl.php in the i18n folder:

es.php:

<?php defined('SYSPATH') or die('No direct script access.');

return array(
    'Good Morning' => 'Buenos Dias',
);

tl.php (is the abbreviation of a human language. No idea which one):

<?php defined('SYSPATH') or die('No direct script access.');

 return array(
        'Good Morning' => 'Magandang Umaga',
    );

view file site.php:

<p><?php echo __('Good Morning'); // would produce 'Buenos dias'?></p>

I'm using Kohana 3. Right now, the only way known method to change the language is to modify I18n::lang('es-es'); in bootstrap.php.

How can I change the preferred language when clicking in an anchor link (an anchor link inside site.php)?

Answer 1

insert this in your before method inside your main controller:

I18n::$lang = 'es-es';

good example of how you can do this with cookies can be found inside the userguide module main controller
