To add a radio button in a Symfony form, you can use the ChoiceType field type with the expanded option set to true.
Here's an example of adding a radio button in a Symfony form:
- Create a form class (e.g., MyFormType) extending AbstractType:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
use SymfonyComponentFormAbstractType;
use SymfonyComponentFormFormBuilderInterface;
use SymfonyComponentOptionsResolverOptionsResolver;
class MyFormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('my_radio', ChoiceType::class, [
'choices' => [
'Option 1' => 'option1',
'Option 2' => 'option2',
'Option 3' => 'option3',
],
'expanded' => true, // Render the choices as radio buttons
]);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => MyFormData::class,
]);
}
}
|
- Create a data class to bind the form data (e.g., MyFormData):
1 2 3 4 5 |
class MyFormData
{
public $my_radio;
// ...
}
|
- In your controller, create a new instance of the form and handle the form submission:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
use SymfonyBundleFrameworkBundleControllerAbstractController;
use SymfonyComponentHttpFoundationRequest;
use SymfonyComponentRoutingAnnotationRoute;
class MyController extends AbstractController
{
/**
* @Route("/my-form", name="my_form")
*/
public function myFormAction(Request $request)
{
$myFormData = new MyFormData();
$form = $this->createForm(MyFormType::class, $myFormData);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
// Handle form submission and redirect
// ...
}
return $this->render('my/template.html.twig', [
'form' => $form->createView(),
]);
}
}
|
- Render the form in your template:
1 2 3 4 5 6 |
{# my/template.html.twig #}
<form method="POST" action="{{ path('my_form') }}">
{{ form_widget(form) }}
<button type="submit">Submit</button>
</form>
|
When you render the form, you will see radio buttons for each option defined in the choices option. The selected option will be stored in the my_radio property of the MyFormData class when the form is submitted.
