我在FormBuilderInterface中创建了一个下拉列表(类别,子类别)而不是输入文本字段时遇到了问题 当我把它改回文本输入时,一切正常。
这是我的FormType
代码namespace Expatservice\ManagerBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Doctrine\ORM\EntityRepository;
class ServiceType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('title')
->add('category', EntityType::class, array(
'class' => 'ExpatserviceCategoryBundle:Category',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('c')
->where('c.parent = 0')
->orderBy('c.title', 'ASC');
},
'choice_value' => 'title',
'choice_label' => 'title'
))
->add('subcategory', EntityType::class, array(
'class' => 'ExpatserviceCategoryBundle:Category',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('c')
->where('c.parent = 2')
->orderBy('c.title', 'ASC');
},
'choice_value' => 'title',
'choice_label' => 'title'
))
->add('description')
->add('image', FileType::class, array('data_class' => null, 'required'=>false));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaultOptions(array('data_class' => 'Expatservice\ManagerBundle\Entity\Service'));
}
public function getName()
{
return 'expantservice_managerbundle_service';
}
}
我理解这个问题,但无法弄清楚如何解决问题,而且在互联网上一无所获。

在处理表单提交时,我应该使用__toString()魔术函数来获取正确的数据类型。
为了确保我们将获得字符串,实体部分应如下所示:
/**
* Get title
*
* @return string
*/
public function getTitle()
{
return $this->title;
}
public function __toString() {
return $this->title;
}
