Symfony 2 - how to pass data to formBuilder?

php symfony formbuilder

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)

答案 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);
    },
));

答案 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' =>'' 
       ));
     }
