I need to be able to do an operation on form data before it gets persisted to the database. The problem is, the operation can be risky and I need the user's consent each time.
I'd like to do this through a confirmation form (with a little message explaining what's going on), not with a Javascript confirm window.
How can I achieve this functionality?
Here is an example of a controller action method that handles the form:
<?php
public function indexAction(Request $request)
{
...
$form = $this->createFormBuilder($myEntity)
->add('someField', 'integer', array('required' => true))
// Lots and lots of fields
->getForm();
if ($request->isMethod('POST')) {
$form->bind($request);
if ($form->isValid()) {
// CUSTOM VALIDATION HERE
// If invalid, must display a new confirmation form to ask user
// if it's alright to do a somewhat risky operation that would
// validate the form data.
// Else, persist the data.
$db = $this->getDoctrine()->getManager();
$db->persist($myEntity);
$db->flush();
return $this->redirect($this->generateUrl('my_path_to_success_page'));
}
}
return $this->render('MyBundle:Preferences:index.html.twig', array(
'form' => $form->createView(),
'errors' => $form->getErrors(),
));
}
