Symfony form choice default value from entity - php

Question

I having some troubles with symfony forms.
I have a boolean variable in my entity. I cant find a way to set that value in my form when i'm editing it.
Entity
namespace AdminBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\Table(name="pages")
*/
class Page
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="text")
*/
protected $slug;
/**
* #ORM\Column(type="text")
*/
protected $title;
/**
* #ORM\Column(type="text")
*/
protected $content;
/**
* #ORM\Column(name="creation_date", type="datetime")
*/
protected $creationDate;
/**
* #ORM\Column(name="is_active", type="boolean")
*/
protected $isActive = true;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set slug
*
* #param string $slug
*
* #return Page
*/
public function setSlug($slug)
{
$this->slug = $slug;
return $this;
}
/**
* Get slug
*
* #return string
*/
public function getSlug()
{
return $this->slug;
}
/**
* Set title
*
* #param string $title
*
* #return Page
*/
public function setTitle($title)
{
$this->title = $title;
return $this;
}
/**
* Get title
*
* #return string
*/
public function getTitle()
{
return $this->title;
}
/**
* Set content
*
* #param string $content
*
* #return Page
*/
public function setContent($content)
{
$this->content = $content;
return $this;
}
/**
* Get content
*
* #return string
*/
public function getContent()
{
return $this->content;
}
/**
* Set creationDate
*
* #param \DateTime $creationDate
*
* #return Page
*/
public function setCreationDate($creationDate)
{
$this->creationDate = $creationDate;
return $this;
}
/**
* Get creationDate
*
* #return \DateTime
*/
public function getCreationDate()
{
return $this->creationDate;
}
/**
* Set isActive
*
* #param boolean $isActive
*
* #return Page
*/
public function setIsActive($isActive)
{
$this->isActive = $isActive;
return $this;
}
/**
* Get isActive
*
* #return boolean
*/
public function getIsActive()
{
return $this->isActive;
}
}
Controller function
public function editAction(Request $request, $pageId)
{
$em = $this->getDoctrine()->getManager();
$page = $em->getRepository('AdminBundle:Page')->find($pageId);
$form = $this->createForm('app_page', $page);
$form->handleRequest($request);
if($form->isValid()) {
$em = $this->getDoctrine()->getEntityManager();
$em->persist($page);
$em->flush();
return $this->redirectToRoute('admin_pages');
}
return $this->render('AdminBundle::editPage.html.twig', array('page' => $page, 'form' => $form->createView()));
}
PageFormType
namespace AdminBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
class PageFormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('title', 'text');
$builder->add('slug', 'text');
$builder->add('isActive', 'choice', array('choices' => array(
'true' => 'Active',
'false' => 'Inactive'
)));
$builder->add('content', 'textarea', array('required' => false));
}
public function getName()
{
return 'app_page';
}
}
As you can see i wrote my self in FormType class what choices it has. And now it is always displaying "Active" instead of displaying Entity's value. How should i do that?
Thanks!

Answer 1

Try to change your isActive in the Entity like
protected $isActive ;
and if you want to make a default true you can make it at the construct like :
public function __construct() {
$this->setIsActive = true ;
}

Answer 2

$builder->add('isActive', ChoiceType::class, [
'choices' => [
'Active' => true,
'Inactive' => false
],
'choices_as_values' => true,
'multiple' => true,
'expanded' => true,
'data' => array(true)
]);

A 2021 Solution: setting form choice default value (data) from entity
Sometimes your choice field values exist in another entity table, which means you cannot populate them using default form data_class. You only get the string value that saved in the form entity, resulting to error: ...must be an object or null, string given...
protected EntityManagerInterface $em;
public function __construct(EntityManagerInterface $em)
{
$this->em = $em;
}
// In your form
->add('membershipType', EntityType::class, [
'class' => MembershipType::class,
'label' => 'Enter membership type here',
'data' => $this->em->getRepository(MembershipType::class)->findOneBy([
'name' => $your_value_here
])
])
