问题代码：
形式：
$builder->add('title', Type\TextType::class, [
'label_attr' => ['class' => 'required label-required'],
]);
$builder->add('isPublished');
$builder->add('imageFile', VichImageType::class, [
'label_attr' => ['class' => 'required label-required'],
'allow_delete' => false,
]);
$builder->add('alt', Type\TextType::class, [
'label_attr' => ['class' => 'required label-required'],
]);
问题：
谁能告诉我，为什么has-error不添加到第三表单字段？要生成错误，title字段正在使用@Assert\NotBlank()并且“图像文件”正在使用我的自定义约束：
FileNotEmpty类：
<?php
namespace Notimeo\CoreBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
/**
* @Annotation
* @Target("CLASS")
*/
class FileNotEmpty extends Constraint
{
/**
* @var string
*/
public $message = 'This field cannot be empty.';
/**
* @var array
*/
public $fields = [];
/**
* @return string
*/
public function validatedBy()
{
return get_class($this).'Validator';
}
/**
* @return string
*/
public function getTargets()
{
return self::CLASS_CONSTRAINT;
}
}
FileNotEmptyValidator类：
<?php
namespace Notimeo\CoreBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
/**
* Class FileNotEmptyValidator
*
* @package Notimeo\CoreBundle
*/
class FileNotEmptyValidator extends ConstraintValidator
{
/**
* @param mixed $protocol
* @param Constraint $constraint
*/
public function validate($protocol, Constraint $constraint)
{
/* @var $constraint FileNotEmpty */
foreach($constraint->fields as $field) {
$method1 = 'get'.ucfirst($field);
$method2 = $method1.'File';
$value1 = call_user_func([$protocol, $method1]);
$value2 = call_user_func([$protocol, $method2]);
if(empty($value1) && empty($value2)) {
$this->context->buildViolation($constraint->message)
->atPath($field.'File')
->addViolation();
}
}
}
}
使用最新的Symfony 3和EasyAdminBundle来生成这个表单。是什么导致了这个问题？
