Validate form in different controller action symfony - php

Question

I have a controller action that returns a form to the view. When the form is submitted, the validation of this form needs to be done in a different action than the action returning the form.
This is a sample of the action that returns the form
/**
* #Route("/AjaxAddQuestionForm/{section}")
* #Template
* #ParamConverter("section", class="AppBundle:Section")
*/
public function ajaxAddQuestionFormAction(Request $request, $section)
{
$question = new Question();
$question->setSection($section);
$addQuestionForm = $this->createForm(new AddQuestionType(), $question);
return array(
'section' => $section,
'addAjaxQuestionForm' => $addQuestionForm->createView(),
);
}
And this is the action in which I am currently trying to get the validation to work.
/**
* #Route("/edit/{form}")
* #Template()
* #ParamConverter("form", class="AppBundle:Form")
*/
public function editAction(Request $request, $form)
{
$em = $this->getDoctrine()->getManager();
(...)
$questionForm = new Question();
$addQuestionForm = $this->createForm(new AddQuestionType(), $questionForm);
$addQuestionForm->handleRequest($request);
if ($addQuestionForm->isValid()) {
$em->persist($questionForm);
$em->flush();
return $this->redirectToRoute('app_form_edit', array('form' => $form_id));
}
(...)
The problem is that the validation in the second action is never called. Any idea on how I can get this working?

Answer 1

You should add form action if you want validate form on other url:
In ajaxAddQuestionFormAction:
$addQuestionForm = $this->createForm(new AddQuestionType(), $question,
array(
'action' => $this->generateUrl('edit_form')
));
edit action route:
*#Route("/edit", name="edit_form")
