Zend表单csrf保护

Question

我正试图用crsf令牌保护我的Zend表单。如果我在表单中添加token元素，它总是会向我返回notEmpty错误消息。我做错什么了吗？谢谢

class Application_Form_Test3 extends Zend_Form {

    public function init() {
        $this->setMethod('post');

//..some elements

        $note = new Zend_Form_Element_Textarea('note');
        $note->addValidator('stringLength', false, array(2, 50));
        $note->setRequired(true);
        $note->class = 'form-control';
        $note->setLabel('Poznámka:');
        $note->setAttrib('placeholder', 'poznamka ke spisu');
        $note->setOptions(array('cols' => '20', 'rows' => '4'));

        $submit = new Zend_Form_Element_Submit('submit');
        $submit->class = 'btn btn-success';
        $submit->setValue('odeslat');

        $this->addElements(array(
            $number,
            $year,
            $owner,
            $note,
            $submit,
        ));

        $this->addElement('hash', 'no_csrf_foo', array('salt' => 'unique'));
    }

}

控制器中的操作：

public function findAction() {
    $request = $this->getRequest();
    $form = new Application_Form_Test3();

    if ($this->getRequest()->isPost()) {
        if ($form->isValid($request->getPost())) {
            var_dump($request->getPost());
        } else {
            var_dump("ERROR");
        }
    }

    $this->view->form = $form;
}

在我看来，我呈现表单并转储错误消息

...
<?php echo $form->renderForm(false); ?>
...
//render single elements here
//eg.  <?php echo $form->note->renderViewHelper(); ?>
...
    <?php var_dump($form->getMessages()) ?>
...

每次验证表单后，我都会收到如下错误消息：

array(2) { ["note"]=> array(1) { ["isEmpty"]=> string(36) "Value is required and can't be empty" }  ["no_csrf_foo"]=> array(1) { ["isEmpty"]=> string(36) "Value is required and can't be empty" } } 

如果我给元素填充了正确的值，最后一个错误总是token-NotEmpty，因此我的表单永远无效。

问题解决了。我没有在视图中呈现令牌元素，因此我在视图中添加了：

<?php echo $form->no_csrf_foo->renderViewHelper(); ?>
