How to set selected option in symfony? - html

Question

Here is my form:
{
$builder
->add('price', ChoiceType::class, [
'label' => false,
'required' => false,
'choices' => [
'0 - 1000 €' => 1,
'1000 - 2000 €' => 2,
'2000 - ∞' => 3,
],
'attr' => [
'class' => 'main-dropdown',
],
])
;
}
So how to pass selected value on twig? Can someone give an advice?

Answer 1

I think you build the form in a separate .with this method you can use of form anywhere you need.
for example, it is your form
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;///To use this field, you must add ChoiceType in form.
class yournameFormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('price', ChoiceType::class, [
'label' => false,
'required' => false,
'choices' => [
'0 - 1000 €' => 1,
'1000 - 2000 €' => 2,
'2000 - ∞' => 3,
],
'attr' => [
'class' => 'main-dropdown',
],
])
;
}
}
You can use this form in a controller like an example below
use AppBundle\Form\yournameFormType;
public function newAction()
{
$YourEntityName = ...;
$form = $this->createForm(yournameFormType ::class, $YourEntityName );
// ...
return $this->render('#App/YourNameTwig.html.twig', array(
'form' => $form->createView()
));
}
and at the end Use the form in twig file
{{ form_start(form) }}
.
.
{{ form_widget(form.price) }}
.
.
.
{{ form_end(form) }}
