Pimcore provides a simple translation-tool based on Zend_Translate.

The only thing you have to do is to register a locale globally (the ZF way), the easiest way is to do that in the Website_Controller_Action.

In the example Website_Controller_Action which is shipped with Pimcore there is already an example.

Once you have registered the locale you can simply use the translate helper of Zend_View in your templates with: <?= $this->translate("translation_key") ?>

Then call the page where you use the translation, once you have done this, pimcore registers the key in the translation administration, and you can edit the text in the grid.

The columns in the translation administration for the languages is generated automatically by the used locales.

Please make sure that all desired languages are set as valid frontend languages in the pimcore system settings as described here. 

Next the translations for all registered languages can be edited in Extras > Translations Website

Example in Website_Controller_Action

<?php
 
class Website_Controller_Action extends Pimcore_Controller_Action_Frontend {
 
public function init () {
 
parent::init();

$locale = new Zend_Locale('en_US');
Zend_Registry::set('Zend_Locale', $locale);
 
}
 
?>

Example in Templates / Views

<div>
    <address>&copy; <?= $this->translate("copyright") ?></address>
    <a href="/imprint"><?= $this->translate("imprint") ?></a>
    <a href="/legal"><?= $this->translate("legal_notice") ?></a>
</div>
