How to combine two entities within one form? - php

Question

I want to use two entities in one form and despite using tips from previous questions which were similar, it doesn't work. I have following controller:
<?php
namespace AppBundle\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use AppBundle\Entity\User;
use AppBundle\Form\UserType;
use AppBundle\Entity\School;
use AppBundle\Form\SchoolType;
class RegistrationController extends Controller
{
/**
* #Route("/register", name="user_register")
*/
public function registerAction(Request $request)
{
$user = new User();
$form = $this->createForm(new UserType(), $user);
$form->add('status','hidden', array('attr' => array('value' => '0') ))
->add('school', new SchoolType());
return $this->render('AppBundle:Main:register.html.twig', array('form' => $form->createView()));
}
}
UserType.php
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Form\Extension\Core\ChoiceList\ChoiceList;
class UserType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('login', 'text', array('attr' => array(
'id' => 'login', 'name' => 'login', 'label' => 'Login:',
'class' => 'form-control', 'required' => true
)))
->add('password', 'password', array('attr' => array(
'id' => 'password', 'name' => 'password', 'label' => 'Password:',
'class' => 'form-control', 'required' => true
)))
;
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\User'
));
}
/**
* #return string
*/
public function getName()
{
return 'appbundle_user';
}
}
SchoolType.php
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class SchoolType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name', 'text', array('attr' => array(
'class' => 'form-control', 'id' => 'schoolName', 'name' => 'schoolName',
'placeholder' => 'np. Szkoła podstawowa nr. 5 w Warszawie', 'label' => 'Nazwa Szkoły',
'required' => true
)))
->add('shortcut', 'text', array('attr' => array(
'class' => 'form-control', 'id' => 'shortcut', 'name' => 'shortcut',
'placeholder' => 'np. SP5Warszawa', 'label' => 'Skrót', 'required' => true
)))
;
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\School'
));
}
/**
* #return string
*/
public function getName()
{
return 'school';
}
}
and finally twig template:
{{ form_start(form) }}
<div class="form-group">
{{ form_row('form.school.name') }}
</div>
<div class="form-group">
{{ form_row('form.school.shortcut') }}
</div>
<div class="form-group">
{{ form_row('form.login') }}
</div>
<div class="form-group">
{{ form_row('form.login') }}
</div>
{{ form_row('form.status') }}
<span style="display:inline-block;">
<button type="submit" class="btn btn-default">Create</button>
{{ form_end(form) }}
Why it doesn't work? I receive following error:
Neither the property "school" nor one of the methods "getSchool()", "school()", "isSchool()", "hasSchool()", "__get()" exist and have public access in class "AppBundle\Entity\User".

Answer 1

Your User class must have a propriety called school.
/**
* #ORM\Entity()
* #ORM\Table(name="users")
*/
class User
{
/**
* #ORM\OneToMany(targetEntity="Bundle\Entity\Schools",mappedBy="user")
*/
protected $school;
Then, generate entities for it,
php app/console doctrine:generate:entities Bundle:User
or write the functions manually:
public function setSchool($school)
{
$this->school= $school;
return $this;
}
public function getSchool()
{
return $this->school;
}

Answer 2

It's telling you exactly what you need to know. In your User entity, you either don't have a relation to your School entity or you are missing a getter & setter for School. Assuming it is a one to one relationship you should have something like:
/**
* #OneToOne(targetEntity="School", inversedBy="user")
* #JoinColumn(name="school_id", referencedColumnName="id")
**/
private $school;
With getter & setter:
public function setSchool(School $school = null)
{
$this->school = $school;
return $this;
}
public function getSchool()
{
return $this->school;
}
Note these should be automatically generated by the doctrine generate entities command. You may simply not have run this if you have the User->School relationship set up correctly and the setter/getter missing.
