Zend Framework form Invalidating the form

I have created a form with zend form. I process the data in one action and then redirect to the another action.

So in case of an error I redirect to the last form, if there was no error I redirect the user to another url.

So when isVa开发者_StackOverflow社区lid() fails I use the getMessages() (the getErrorMessages doesn't return anything) to get the messages, serialize it, place it in a session property and then redirect to the form page. My problem is now setting those error msg's in the form to let the user know there was a problem.

I have tried this

$form->setErrors(unserialize($this->_session->form_error_msgs));

But this doesn't do anything. What do I have to do to display the error msgs next to the fields??

you should add the error to the field, for example

 $form->fieldname->addError('error message');

your code might not be working because you haven´t configured the form decorators...
