如何在Zend 2框架中将表单连接到另一个phtml视图

Question

I am new at Zend2:

I have a form, and in the first stage I create a new ViewModel and return it:

return new ViewModel(array('form' => $form, 'messages' => $messages));

In the post stage when the data comes back from the browser, how can I connect this same form to a new View (which has the same elements maybe less, maybe more) or create another form and rassign it the old form's data and relate it to a new view to show?

Any help would be appreciated.

EDIT:

I tried to do the following:

$form->setAttribute('action', $this->url('auth/index/login-post.phtml'));

But still shows the old one.

When I do this:

return $this->redirect()->toRoute('auth/default', array('controller' => 'index', 'action' => 'login-post'));

I get error page: The requested controller was unable to dispatch the request.

When I get the post of the request I need to load another view, I mean how do I specify which view is connected to which form?

Answer 1

The forms do not themselves have any knowledge of the view. If you wish to change the view after completing the form submission; where this new view provides perhaps a different form, this is something that should be done within the controller.

A (non-working) example with a few options on how a different view could be returned.

class FooController extends AbstractActionController
{

    public function getFooForm()
    {
        return $this->getServiceLocator()->get('Form\Foo');
    }

    public function getBarForm()
    {
        return $this->getServiceLocator()->get('Form\Bar')
    }


    public function fooAction()
    {
        $request = $this->getRequest();
        $form    = $this->getFooForm();

        if ($request->isPost()) {
            $form->setData($request->getPost());

            // Is the posted form vaild
            if ($form->isValid()) {

                // Forms validated data
                $data = $form->getData(); 

                // Now there are a few options

                // 1. Return a new view with the data
                $view = new ViewModel($data);
                $view->setTemplate('path/to/file');

                return $view;

                // OR Option 2 - Redirect

                return $this->redirect()->toRoute('bar', $someRouteParams);


                // Option 3 - Dispatch a new controller action
                // and then return it's view model/response

                // We can also pass on the posted data so the controller
                // action that is dispathed will already have our POSTed data in the
                // request
                $request->setPost(new \Zend\Stdlib\Parameters($data));

                return $this->forward()->dispatch('App\Controller\Foo', array('action' => 'bar'));

            }
        }
        // Render default foo.phtml or use $view->setTemplate('path/to/view')
        // and render the form, which will post back to itself (fooAction)
        return new ViewModel(array('form' => $form));
    }


    public function barAction()
    {
        $request = $this->getRequest();
        $form    = $this->getBarForm();

        if ($request->isPost()) {
            $form->setData($request->getPost());
            // ....      
        }

        // Renders the bar.phtml view
        return $this->viewModel(array('form' => $form));
    }

}

From what I understand form your question, you would need to be using option 3 as the new view should populate a second form with it's already validated data.
