POHow to handle forms that are used on multiple pages?

Body
copied!<p>I have a form I need to use on multiple pages:</p> <p><strong>Controller</strong></p> <pre><code>$emailForm = $this->get('form.factory')->createNamedBuilder('form', 'email_form') ->add('email', 'email') ->add('subject', 'text') ->add('body', 'textarea') ->getForm(); $request = $this->get('request'); if ($request->getMethod() == 'POST' && $request->request->has('email_form') ) { $emailForm->bindRequest($request); if ($emailForm->isValid()) { // do stuff ... $this->get('session')->setFlash('email_sent', "Woey, mail sent successfully!"); // Redirect on the same url to prevent double posts return $this->redirect($this->generateUrl($this->getRequest()->attributes->get('_route'))); } } return $this->render('Bundle:Form:index.html.twig', array('email_form' => $emailForm->createView())); </code></pre> <p><strong>Template</strong></p> <pre><code>{% if app.session.getFlash('email_sent') %} <p>{{ app.session.getFlash('email_sent') }}</p> {% endif %} <form action="{{ path(app.request.attributes.get('_route')) }}" method="post" {{ form_enctype(email_form) }}> {{ form_widget(email_form) }} <p><input type="submit" class="submit" value="Send" /></p> </form> </code></pre> <p>It's really just standard Symfony2 form, almost like from tutorial.</p> <p>I can't figure how can I efficiently use it on multiple pages (in multiple controller actions) without repeating myself (too much). So far I tried:</p> <ul> <li>putting the logic into Base controller, which is parent for every controller where I want to have this form. There were 2 problems with this approach: <ul> <li>I couldn't figure how to redirect properly to the same page</li> <li>I had to call method from parent in every action, which isn't really a problem, but I guess there has to be some more elegant way</li> </ul></li> <li>rendering controller using <a href="http://symfony.com/doc/current/book/templating.html#embedding-controllers" rel="nofollow noreferrer">embedded controllers</a> in twig. However, I couldn't figure <a href="https://stackoverflow.com/questions/6984429/redirect-from-embedded-controller">how to redirect properly</a>.</li> </ul> <p>So, what's the common approach to such forms?</p> <p><strong>Edit:</strong></p> <p>I'm looking for a no script solution.</p>
