表单类型映射false symfony2

Question

我遇到了一个带有mapped = false的formtype的问题.

在控制器中,我调用了表单:

$form = $this->createForm(new JurisdictionUserNewType(), $jurisdiction_user);

这是我的JurisdictionUserNewType:

class JurisdictionUserNewType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $transformer = new CapitalLetterToLowerCaseTransformer();

        $builder
            ->add('name', 'text')
            ->add($builder->create('email', 'email')
                           ->addModelTransformer($transformer))
            ->add('securityUser', new SecurityUserType(), array('mapped' => false))

            ->add('save', 'submit');

    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
           'data_class' => 'Radmas\Open010Bundle\Document\JurisdictionUser'
        ));
    }

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

这是我的SecurityUserType:

class SecurityUserType extends AbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('first_name', null, ['label' => 'profile.edit.labels.first_name', 'icon_class' => 'fa fa-user'])
            ->add('last_name', null, ['label' => 'profile.edit.labels.last_name', 'icon_class' => 'fa fa-user'])
            ->add('nickname', null, ['label' => 'profile.edit.labels.nickname',
                'attr' => [ 'help_text' => 'profile.edit.labels.nickname_help'], 'icon_class' => 'fa fa-globe']);
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
           'data_class' => 'Radmas\SecurityBundle\Document\SecurityUser'
        ));
    }

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

当我在表单中放入数据时,我在modalview中得到了对象辖区,但是我没有得到对象securityUser.

如果您'mapped' => false在任何字段上设置,则表示该字段与您的实体无关,因此当您从提交的表单中检索实体时,您无法获得该字段.

无论如何,您可以从表单中获取单个字段,如下所示:

$form->handleRequest($request); 
if ($form->isValid()) { 
    $entity = $form->getData(); 
    $securityUser = $form->get('securityUser')->getData();    
}
