提交失败后打开引导程序模式

Question

I got a login/register form in a modal. And after the submit failed and the page reloaded, I want to open the form again and add a second modal below the login modal.

My code doesn't work:

if ($this->getRequest()->isPost())
    {
        $form->setData($this->getRequest()->getPost());
        /** @var \Zend\Authentication\Adapter\DbTable $Adapter */
        if ($form->isValid())
        {
            $data    = $form->getData();
            $Adapter = $this->authService->getAdapter();
            $Adapter
                ->setIdentity($data['email'])
                ->setCredential($data['password']);
            $authResult = $this->authService->authenticate();

            if (!$authResult->isValid())
            {
                echo "<script>
                $(document).ready(function(){
                  alert('hi');
                });
                    </script >";
            }

            else
            {
                return $this->redirect()->toRoute("blog");
            }
        }

        else
        {
            return new ViewModel(
                [
                    'form' => $form,
                ]
            );
        }
    }

As of you're doing an redirect ( return $this->redirect()->toRoute("blog"); ) to another route, your "echo" doesn't render. The new HTML of new Route will render.

So your echo has to be in the new route (may via an Parameter)
