Form:
<?php
namespace App\Form;
use App\Entity\Team;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\Form\FormInterface;
class addMatchType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('division', EntityType::class, array(
'class' => 'App\Entity\Team',
'placeholder' => '',
'choice_label' => 'division',
));
$formModifier = function (FormInterface $form, Team $team = null) {
$league = null === $team ? array() : $team->getLeague();
$form->add('league', EntityType::class, array(
'class' => 'App\Entity\Team',
'placeholder' => '',
'choices' => $league,
));
};
$builder->addEventListener(
FormEvents::PRE_SET_DATA,
function (FormEvent $event) use ($formModifier) {
// this would be your entity, i.e. SportMeetup
$data = $event->getData();
$formModifier($event->getForm(), $data->getDivision());
}
);
$builder->get('division')->addEventListener(
FormEvents::POST_SUBMIT,
function (FormEvent $event) use ($formModifier) {
// It's important here to fetch $event->getForm()->getData(), as
// $event->getData() will get you the client data (that is, the ID)
$team = $event->getForm()->getData();
// since we've added the listener to the child, we'll have to pass on
// the parent to the callback functions!
$formModifier($event->getForm()->getParent(), $team);
}
);
}
}
Twig:
{{ form_start(form) }}
{{ form_row(form.division) }} {# <select id="meetup_sport" ... #}
{{ form_row(form.league) }} {# <select id="meetup_position" ... #}
{# ... #}
{{ form_end(form) }}
