use Symfony\Component\Form\FormInterface; class MyController { public function myAction(FormInterface $form) { $viewData = $form->getViewData(); // Do something with the data } }
use Symfony\Component\Form\FormInterface; class MyFormType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('name', TextType::class); } public function configureOptions(OptionsResolver $resolver) { $resolver->setDefaults([ 'data_class' => MyEntity::class, ]); } } class MyController { public function createAction(Request $request) { $form = $this->createForm(MyFormType::class); $form->handleRequest($request); if ($form->isSubmitted() && $form->isValid()) { $entity = $form->getData(); $viewData = $form->getViewData(); // Do something with the data } // ... } }In this example, we define a FormType that has a single field, 'name'. We then define a Controller in which we create an instance of the form, handle the incoming request, and, if the submitted data is valid, retrieve the data and assign it to the $viewData variable. We can then use this data to perform some action, such as persisting it to a database. Overall, the FormInterface getViewData method is a useful tool for retrieving the data associated with a given form view. This method is part of the Symfony\Component\Form package in PHP.
