I have symfony form with choice field. I want to load choices from my entity class static method. can i use data or CallbackChoiceLoader? what is the best practise?
this is my field:
class CarType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('type', ChoiceType::class, [
// This choices I would like to load from:
// 'choices' => $car::getTypes(),
'choices' => [
'Critical' => 'critical',
'Medium' => 'medium',
'Info' => 'info',
],
'label' => 'Type'
])
->add('name', TextType::class, [
'label' => 'Name'
])
->add('save', SubmitType::class, [
'label' => 'Save'
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => 'AppBundle\Entity\Car'
]);
}
public function getName()
{
return 'car';
}
}
This is my entity:
/**
* @ORM\Entity
* @ORM\Table(name="car")
*/
class Car
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* @var string $type
*
* @Assert\NotBlank()
* @ORM\Column(name="type")
*/
private $type;
/**
* @var string $name
*
* @Assert\NotBlank()
* @ORM\Column(name="name")
*/
private $name;
/**
* @var \DateTime $created
*
* @ORM\Column(name="created", type="datetime")
*/
private $created;
private static $types = ['main', 'custom'];
public function __construct()
{
$this->created = new \DateTime('now', new \DateTimeZone('Europe/Ljubljana'));
}
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Get types
*
* @return array
*/
public function getTypes()
{
return self::$types;
}
/**
* Set type
*
* @param string $type
*
* @return Car
*/
public function setType($type)
{
if (in_array($type, $this->getTypes())) {
$this->type = $type;
}
return $this;
}
/**
* Get type
*
* @return string
*/
public function getType()
{
return $this->type;
}
/**
* Set name
*
* @param string $name
*
* @return Car
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Set created
*
* @param \DateTime $created
*
* @return Car
*/
public function setCreated($created)
{
$this->created = $created;
return $this;
}
/**
* Get created
*
* @return \DateTime
*/
public function getCreated()
{
return $this->created;
}
How and what can i use to load choices from $car::getTypes() method like i commented in form so that the choices are loaded dynamicly based on values in getTypes entity method?
