还在与Symfony3和Doctrine争吵。只是试图从数据库中简单地自动填充表单。我有两张桌子 - 国家和州。
countries.php

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
/**

private $id;
/**

private $country_code;
/**

*/
private $country_name;
public function __toString()
{
return $this->country_name;
}
/**

protected $states;
public function __constructor()
{
$this->states = new ArrayCollection();
}
/**

return $this->id;
}

public function getCountryCode()
{
return $this->country_code;
}
/**

*/
public function setCountryCode($country_code)
{
$this->country_code = $country_code;
}
/**

*/
public function getCountryName()
{
return $this->country_name;
}
/**

public function setCountryName($country_name)
{
$this->country_name = $country_name;
}
/**

/**

public function setStates($states)
{
$this->states = $states;
}

还有formfile：
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Component\Form\Extension\Core\Type\RepeatedType;

use Symfony\Component\Form\FormEvents;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\FormInterface;
use AppBundle\Entity\Forms\States;
class UserType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name', TextType::class,
array('label' => false,
'mapped'=>false,
'attr' => array(
'placeholder' => 'FirstName'
)))
->add('lastname', TextType::class,
array('label' => false,

])

array(

'data' => true,
'mapped'=>false,
))
->add('city', TextType::class,
array('label' => false,

'attr' => array(

)))
->add('postcode', TextType::class,

)))
->add('CountryName', EntityType::class, array(

;
$formModifier = function (FormInterface $form, States $states = null) {
$positions = null === $states ? array() : $states->getStates();
$form->add('states', EntityType::class, array(
'class' => 'AppBundle\Entity\Forms\States',
'placeholder' => '',
'choices' => $positions,
));
};
$builder->addEventListener(
FormEvents::PRE_SET_DATA,
function (FormEvent $event) use ($formModifier) {
// this would be your entity, i.e. SportMeetup
$data = $event->getData();
$formModifier($event->getForm(), $data->getCountryName());
}
);
$builder->get('CountryName')->addEventListener(
FormEvents::POST_SUBMIT,
function (FormEvent $event) use ($formModifier) {
// It's important here to fetch $event->getForm()->getData(), as
// $event->getData() will get you the client data (that is, the ID)
$countries = $event->getForm()->getData();
// since we've added the listener to the child, we'll have to pass on
// the parent to the callback functions!
$formModifier($event->getForm()->getParent(), $countries);
}
);
}
}
但是仍然有错误：
Type error: Argument 2 passed to AppBundle\Form\UserType::AppBundle\Form\{closure}() must be an instance of AppBundle\Entity\Forms\States, instance of AppBundle\Entity\Forms\Countries given, called in /var/www/hostera.dev/public_html/src/AppBundle/Form/UserType.php on line 139
Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalThrowableError: "Type error: Argument 2 passed to AppBundle\Form\UserType::AppBundle\Form\{closure}() must be an instance of AppBundle\Entity\Forms\States, instance of AppBundle\Entity\Forms\Countries given, called in /var/www/hostera.dev/public_html/src/AppBundle/Form/UserType.php on line 139" at /var/www/hostera.dev/public_html/src/AppBundle/Form/UserType.php line 111
我认为与Doctrine Association有关，但我无法弄清楚是什么。
