我想知道如何在我的createForm函数中正确传递我的实体和另一个变量?
让我解释一下,我想这样做:
$repo = $em->getRepository('ProjectBundle:Organisation\Organisation');
$list = $repo->children($this->getUser()->getOrganisation());
$form = $this->createForm('ProjectBundle\Form\Robot\RobotType', array($entity,$list));
我需要将另一个变量传递给我的FormType,所以我直接使用数组。
我的FormType:
<?php
namespace ProjectBundle\Form\Robot;
use ProjectBundle\Entity\Robot\Robot;
use ProjectBundle\Form\User\UserType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class RobotType extends AbstractType
{
/**
* {@inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('serial_number')
->add('shell_color',ChoiceType::class,array(
'choices' => Robot::getArrayShellColor()
))
->add('tray1Color',ChoiceType::class,array(
'choices' => Robot::getTrayColor()
))
->add('tray2Color',ChoiceType::class,array(
'choices' => Robot::getTrayColor()
))
->add('tray3Color',ChoiceType::class,array(
'choices' => Robot::getTrayColor()
))
->add('hasBattery')
->add('volume')
->add('organisation',null,array('choices' => $options['data'][1]));
}
/**
* {@inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'ProjectBundle\Entity\Robot\Robot'
));
}
/**
* {@inheritdoc}
*/
public function getBlockPrefix()
{
return 'projectbundle_robot_new';
}
}
在这里,我需要为组织字段获取变量$ list,因此它是$options['data'][1]
。
但我有一个错误,我理解但我不知道如何纠正:
The form's view data is expected to be an instance of class ProjectBundle\Entity\Robot\Robot, but is a(n) array. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms a(n) array to an instance of ProjectBundle\Entity\Robot\Robot.
这是正常的,因为现在我将它传递给一个数组,它是我的变量$options['data'][0]
,它现在包含我的对象。
怎么办? 谢谢

您应该将ProjectBundle \ Entity \ Robot \ Robot实体作为第二个参数传递给createForm方法,将options数组作为第三个参数传递。
$form = $this->createForm('ProjectBundle\Form\Robot\RobotType', $entity, array($list));
