require_once 'Zend/Registry.php';
 
class IndexController extends Zend_Controller_Action
{
    public function preDispatch()
    {
        $locale = new Zend_Locale();
        $translate = new Zend_Translate('csv', '../application/msg_en.csv', 'en');
        $translate->addTranslation('../application/msg_ja.csv', 'ja');
        if (! $translate->isAvailable($locale->getLanguage()))
        {
            $translate->setLocale('en');
        }
        else
        {
            $translate->setLocale('auto');
        }
        Zend_Registry::set('Zend_Translate', $translate);
    }
 
    /**
     * This function returns the form used for
     * adding comments in blog application
     */
    public static function getAddCommentForm()
    {
        $form = new Zend_Form(array(
            'method'   => 'post',
            'elements' => array(
                'comments' => array('textarea', array(
                    'required' => true,
                    'label' => 'Write your comments'
                )),
                'submit' => array('submit', array(
                    'label' => 'Send'
                ))
            ),
        ));
 
        return $form;
    }
 
    public function indexAction()
    {
        $form = $this->getAddCommentForm();
 
        if ($this->getRequest()->isPost()) {
            if ($form->isValid($_POST)) {
                $values = $form->getValues();
                $this->view->values = $values;
            }
        }
 
        $this->view->form = $form;
    }
}
2.Create View
Create the file application/views/scripts/index/index.phtml as following content.

<ul>
      <?php foreach ($this->values as $value) :?>
