How to Use the submit() Function to Handle Form Submissions
2.3
The handleRequest() method was introduced in Symfony 2.3.
With the handleRequest() method, it is really easy to handle form
submissions:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
use Symfony\Component\HttpFoundation\Request;
// ...
public function newAction(Request $request)
{
$form = $this->createFormBuilder()
// ...
->getForm();
$form->handleRequest($request);
if ($form->isValid()) {
// perform some action...
return $this->redirectToRoute('task_success');
}
return $this->render('AcmeTaskBundle:Default:new.html.twig', array(
'form' => $form->createView(),
));

Calling Form::submit() manually
2.3
Before Symfony 2.3, the submit() method was known as bind().
In some cases, you want better control over when exactly your form is submitted and what data is passed to it. Instead of using the handleRequest() method, pass the submitted data directly to submit():
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
use Symfony\Component\HttpFoundation\Request;
// ...
public function newAction(Request $request)
{
$form = $this->createFormBuilder()
// ...
->getForm();
if ($request->isMethod('POST')) {
$form->submit($request->request->get($form->getName()));
if ($form->isValid()) {
// perform some action...
return $this->redirectToRoute('task_success');
}
}
return $this->render('AcmeTaskBundle:Default:new.html.twig', array(
'form' => $form->createView(),
));
}Passing a Request to Form::submit() (Deprecated)
2.3
Before Symfony 2.3, the submit method was known as bind.
Before Symfony 2.3, the submit() method accepted a Request object as a convenient shortcut to the previous example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
use Symfony\Component\HttpFoundation\Request;
// ...
public function newAction(Request $request)
{
$form = $this->createFormBuilder()
// ...
->getForm();
if ($request->isMethod('POST')) {
$form->submit($request);
if ($form->isValid()) {
// perform some action...
return $this->redirectToRoute('task_success');
}
}
return $this->render('AcmeTaskBundle:Default:new.html.twig', array(
'form' => $form->createView(),
));
}Passing the Request directly to submit() still works, but is deprecated and will be removed in Symfony 3.0. You should use the method handleRequest() instead.
