use multi entity in form builder in symfony2

Question

i want to use more than one entity to create form in createformbuilder . forexample i want to have a form with many fields from many entity and i want to check condition for view fields

userEntity -> email , password 
resselerEntity - > (userEntity fields) + managerName , managerFamily
leaderEntity - > (userEntity fields) + credit

and if i want to show resseler fields , must show all fields of userEntity and resselerEntity

if want to show userEntity , must show all fields of userEntity

and etc,

so how can i solve this solution ? Thanks in advance!

Answer 1

Most common solution is to create single forms for (in your case):

• userEntity
• ressellerEntity

Then, create a new form that have two fields of userEntityFormType and ressellerEntityFormType.

In that way you can:

• Separate your constraints
• Use elsewhere single form

Something like that

class UserEntityType extends AbstractType
{
 public function BuildForm(FormBuilderInterface $builder, array $options)
 {
  $builder->add('firstField')
          ->add('secondField')
          [...]
          ->lastField;
 }

 public function getName()
 {
  return 'UserEntityType ';
 }
}


class RessellerEntityType extends AbstractType
{
 public function BuildForm(FormBuilderInterface $builder, array $options)
 {
  $builder->add('firstField')
          ->add('secondField')
          [...]
          ->lastField;
 }

 public function getName()
 {
  return 'RessellersEntityType ';
 }
}



class AggregateEntityType extends AbstractType
    {
     public function BuildForm(FormBuilderInterface $builder, array $options)
     {
      $builder->add('userEntityField',UserEntityType,array('multiple'=>true)
              ->add('ressellersEntityField',RessellersEntityType,array('multiple'=>true));
     }

     public function getName()
     {
      return 'AggregateEntityType ';
     }
    }

Answer 2

I think Don got you most of the way there. Add a construct argument to your UserType

public function __construct($otherEntityType) // Reseller, Leader etc.

Then use otherEntityType to determine which fields are created for UserType.

Answer 3

As far as I understand your problem, you should use type inheritance:

class UserType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('password')
        ;
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => '\Hamid\User',
        ));
    }

    public function getName()
    {
        return 'hamid_user';
    }
}

class ResellerType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('managerName')
            ->add('managerFamily')
        ;
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => '\Hamid\Reseller',
        ));
    }

    public function getName()
    {
        return 'hamid_reseller';
    }

    public function getParent()
    {
        return 'hamid_user';
    }
}

Then use the right form for each entity. If, for whatever reason, you need a single form that adapts to the class of the entity set to the form, you need to use form events, as explained in the documentation .
