Usually i user translation in View with this code :
<?php echo $this->translate("hello"); ?>
How do i get a translation in the Controller?
If you're creating the zend_translate object in the bootstrap, you can set it in the Zend_Registry for later use:
Zend_Registry::set('translate', $translate);
and then use it in the controller:
$translate = Zend_Registry::get('translate');
$translate->translate("hello");
As far as I know, Zend_Controller doesn't include built-in support for zend_translate.
