2.3 新版功能: The handleRequest()
method was introduced in Symfony 2.3.
With the handleRequest() method, it is really easy to handle form
submissions:
use SymfonyComponentHttpFoundationRequest;
// ...
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(),
));
}

2.3 新版功能: 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():
use SymfonyComponentHttpFoundationRequest;
// ...
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(),
));
}
2.3 新版功能: 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:
use SymfonyComponentHttpFoundationRequest;
// ...
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.
