1. MINIMUM to check how it works

In Your View use function __(), for example, write in English (main language):

<?php echo __('My name is Tom');?>

Then in Your .po file for French /app/Locale/fra/LC_MESSAGES/default.po translate:

msgid "My name is Tom"
msgstr "Mon nom est Tom"

You can use poedit or good PHP editor (UTF-8) like eclipse

Then in Your controller - can be AppController.php -> public function beforeFilter() You can set Your language like:

$this->Session->write('Config.language', 'fra');

don't forget to set Your main language in /Config/core.php like:

Configure::write('Config.language', 'eng');

and use session component - in Your controller:

public $components = array('Session');


  • add function to init language like $this->_setLanguage(); to get language from URL params
  • add function to switch language with links in Your view/site layout with language param
  • set routing in Your Config/routes.php
  • can extends HtmlHelper to add language param to all your links, like:

App::uses('HtmlHelper', 'View/Helper'); class MyHtmlHelper extends HtmlHelper {

    public function url($url = null, $full = false) {

       if(!isset($url['language']) && isset($this->params['language'])) {
          $url['language'] = $this->params['language'];
        return parent::url($url, $full);


table with locale field for all languages:
