Symfony 2 - how to pass data to formBuilder?

问题

I'm using entity choice list in my form. I want to use only specific entities (in example: only groups that user belongs to) So, in controller, I'm getting these groups, and trying to pass them into formBuider.

Controller:

/.../
$groups = $em->getRepository('VendorMyBundle:Group')->getUserGroups($user);
$form = $this->createForm(new Message($groups), $message);
/.../

so, what now? how to use it in formBuilder? how to change this line to use passed array of groups?

->add('group','entity',array('class' => 'Vendor\MyBundle\Entity\Group', 'label'=>'Group:'))

or in the other way:

class MessageType
{
/.../
  public function buildForm(FormBuilder $builder, array $options)
  {
    $builder
      ->add('group','entity',
        array(
          'class' => 'Vendor\MyBundle\Entity\Group',
          'property' => 'name',
          'query_builder' => function ($repository) {
            $qb = $repository->createQueryBuilder('group');
            $qb->add('where', 'group.administrator = :user');
            $qb->setParameter('user', $user->getId());
            return $qb;
          },
          'label' => 'Group'
        )
      )
      // Continue adding fields
    ;
  }
/.../
}

so how can i get object $user to use in form builder? ($user represent current logged user)

回答1:

You can give the object you want to use in the __construct() method.

Eg :

$form = $this
    ->get('form.factory')
    ->create(new ApplyStepOneFormType($this->company, $this->ad), $applicant);

In your form type :

function __construct(\Your\Bundle\Entity\Company $company, \DYB\ConnectBundle\Entity\Ad $ad) {
    $this->company = $company;
    $this->ad = $ad;
}

And then in your form type in buildForm method :

$company = $this->company;    
$builder->add('ad', 'entity', array(
    'class' => '\Your\Bundle\Entity\Ad',
    'query_builder' => function(\Your\Bundle\Repository\AdRepository $er) use ($company) {
        return $er->getActiveAdsQueryBuilder($company);
    },
));

回答2:

//In controller pass the value which you want to use in builder form in array like

$object = new Question();
$form->create(new QuestionType() , $object , array('sqtname'=>2,'question_type'=>2));


//In Form type class
public function buildForm(FormBuilderInterface $builder , array $options)
    {  
     //for setting data field dynamically 
  if (array_key_exists('question_type', $options) && $options['question_type'] != '') {
    $data = $em->getReference("RecrutOnlineStandardBundle:StdQuestionType",$options['question_type']->getId());
  } else {
    $data = "";
  }


  $builder->add('StdQuestionType', 'entity', array(
        'class' => 'TestStandardBundle:StdQuestionType',
        'property' => 'name',
        'empty_value' => 'Sélectionner un question type',
        'required' => true,
        'data' => $data,
        'query_builder' => function(EntityRepository $er ) use ( $options ) {
            if (isset($options['sqtname']) && $options['sqtname'] != '') {
                return $er->createQueryBuilder('sqt')
                                ->where("sqt.name!= ".$options['sqtname']);
            } else{
               return $er->createQueryBuilder('sqt');
            }
        }
    ));
 }

 public function setDefaultOptions(OptionsResolverInterface $resolver)
     {
       $resolver->setDefaults(array(
         'data_class' => 'Test\QuestionBundle\Entity\Question',
         'required' => false,
         'sqtname' => '',
         'question_type' =>'' 
       ));
     }

Bacteries' solution IS NOT a good one. For example, if you declare your type as service, it is impossible to pass an object to constructor.

A perfect solution is options - just pass data as option to form builder.

回答4:

If you want to use custom query, you have to set query_builder option as follows:

use Doctrine\ORM\EntityRepository;

...

$message = new Message();

$form = $this->createFormBuilder($message)
             ->add('group', 'entity', array(
                   'class' => 'Vendor\MyBundle\Entity\Group',
                   'label'=>'Group:',
                   'query_builder' => function(EntityRepository $er) {
                       return $er->createQueryBuilder('g')
                                 ->... // whatever you want to do
                       }
                    ))
             ->getForm();

You can find more info about query builder in Doctrine manual and about options for entity in Symfony2 manual.

Bacteries' solution is a real good one. Just a note to save headache to other guy like me :)

In this part may I point out the use ($company) part. It was hidden by the frame and of course nothing works properly without it.

$builder->add('ad', 'entity', array(
   'class' => 
      '\Your\Bundle\Entity\Ad',
   'query_builder' => 
      function(\Your\Bundle\Repository\AdRepository $er) use ($company) {
            return $er->getActiveAdsQueryBuilder($company);
      },
    )
);

Best way (my opinion) is give to your form entityManager and select all you need in it. But don't forget to declare empty key in setDefaults() otherwise data won't pass to your builder.

Something like this one

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $options['em']->getRepository(''); // select all you need
    $builder->add('title', 'text')
            ->add('content', 'textarea');
}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Main\BlogBundle\Entity\Post',
        'validation_groups' => array('post'),
        'required' => false,
        'em' => null // this var is for your entityManager
        ));
}

Apply EM as simple option...
