[fw-general] Zend_Form | Redirect to a different URL if the form is invalid

[AmirBehzad Eslami]

Dear list,

Is it possible to redirect to a different URL if the form is invalid?
The new URL should contain the submitted form with the
user-provided values and error-messages.
I tried the following code, but it failed; the displayed form is fresh.

            if (!$form->isValid($this->getRequest()->getPost())) {
                // Failed validation; redisplay form
                $this->_helper->_redirector->setCode(303)
                                        ->setExit(true)
                                        ->setGoto('#error-msg');
                return;
            }

How can keep the form's data and its state
after the redirection (without using Sessions)?

Thank you in advance,
Behzad
