Access form data dynamically in symfony 4

Question

I have created following simple form in symfony 4.

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name', TextType::class)
        ->add('email', EmailType::class)
        ->add('message',TextareaType::class)
    ;
}

I access these data from a controller method like following:

$form = $this->createForm(ContactType::class);
$form->handleRequest($request);
$formdata = $form->getData();

$concatenatedData = implode (",", array("Name: ".$formdata['name'], "E-mail: ".$formdata['email'], "Message: ".$formdata['message']));

Now i need to add more fields in the form. In that case, I need to loop through the $formdata and get those values in $concatenatedData. I am new in symfony. Can anyone give me any hints how to do that dynamically in symfony 4 ? Many thanks in advance.

Answer 1

create a class that you need after defining in form class

class ContactType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('name');
    $builder->add('price');
}

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => Content::class,
    ));
}
}

Follow

$content = new Content();
$form = $this->createForm(ContactType::class, $content);
$form->handleRequest($request);
$formdata = $form->getData();

$content->getName();
$content->getOther();
