Get value from EntityType Symfony - php

Question

I can not get value from EntityType. I have last version 3.3.6.
class BuildType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array
$options)
{
$builder
->add('title', TextType::class)
->add('save', SubmitType::class, array('label' => 'Create Post'))
->add('team', CollectionType::class, array(
// each entry in the array will be an "email" field
'entry_type' => TeamType::class,
// these options are passed to each "email" type
'entry_options' => array(
'attr' => array('class' => 'form-control'),
),
'label' => false,
'allow_add' => true,
'prototype' => true,
'mapped' => false
));
}
}
class TeamType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array
$options)
{
$builder
->add('name', EntityType::class, array(
'placeholder' => 'Choice a champ',
'required' => true,
'class' => 'AppBundle:Champions',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('c')
->orderBy('c.name', 'ASC');
},
'choice_label' => 'name',
'choice_value' => 'id',
'attr' => array('class' => 'dropdown'),
));
}
I tried all but i cannot take value of 'name' of TeamType. After submission form, i do
foreach ($form["team"]->getData() as $value) {
'name' => $value['name']
but the value is empty. If i try dump request and the value is there. The other values i can get it and save in Database. Only EntityType i can not.
Someone know how do?

Answer 1

EntityType returns as the object. You should use model getter functions.
$form->get('name')->getData()->getId(); // getName() vs..
Here is a similar example.
symfony how get selected data from select

Answer 2

I suppose that you are using ManyToOne relationship.
With AJAX
if you are trying get data after submitted, You can do this first in your view:
$('#elementWhereYouAreTEAMType').find('input').each(function (i,v) {
var valTeam = $(this).val(); //take value
// adding data, create an associative array.
formData.append("team["+ i +"]", valTeam);
});
You must put formData like data argument to ajax JQuery
Now, server side:
public function createTeamNow(Request $request) {// ajax
$teams = $request->request->get('team'); // getting array
if(!is_null($teams)) {// if user added team
foreach ($teams as $team) {
// dump($team);
//create an instance for each element, it does not replace a data with the above
$teamType = new TeamType();
$teamName->setName($team);
$this->em->persist($teamType);
}
}
}
Without AJAX
/**
* #Route("/slim/1" , name="data_x")
*/
public function slimExampleAction(Request $request)
{
$form = $this->createForm(TeamType::class);
$form->handleRequest($request);
if ($form->isSubmitted() /*&& $form->isValid()*/) {
// When you've ManyToOne relationship, that field returns ArrayCollection class, it has several method to get data on differents ways, iterate with it, for example toArray is one
$data = $form->getData();
dump($data->getDescription()->toArray());die;
}
return $this->render('AppBundle:view.html.twig', array(
'form' => $form->createView(),
));
}
