Assume for a moment that this form utilizes an imaginary Animal
document object class from a ZooCollection
that has only two properties ("name" and "color") in symfony2.
I'm looking for a working simple stupid solution, to pre-fill the form fields with the given object auto-magically (eg. for updates ?).
Acme/DemoBundle/Controller/CustomController
:
public function updateAnimalAction(Request $request)
{
...
// Create the form and handle the request
$form = $this->createForm(AnimalType(), $animal);
// Set the data again << doesn't work ?
$form->setData($form->getData());
$form->handleRequest($request);
...
}
You should load the animal object, which you want to update. createForm() will use the loaded object for filling up the field in your form.
Assuming you are using annotations to define your routes:
/**
* @Route("/animal/{animal}")
* @Method("PUT")
*/
public function updateAnimalAction(Request $request, Animal $animal) {
$form = $this->createForm(AnimalType(), $animal, array(
'method' => 'PUT', // You have to specify the method, if you are using PUT
// method otherwise handleRequest() can't
// process your request.
));
$form->handleRequest($request);
if ($form->isValid()) {
...
}
...
}
I think its always a good idea to learn from the code generated by Symfony and doctrine console commands (doctrine:generate:crud). You can learn the idea and the way you should handle this type of requests.
