Question

我正在使用没有类的表单构建器，并且有两个字段，每个字段都有约束：

$form = $this->createFormBuilder()
        ->add('name', 'text', array(
            'required'=>false,
            'constraints'=> new Length(array('min'=>3)
        ))
        ->add('dob', 'date', array(
            'required'=>false,
            'constraints'=> new Date()
        ))
        ->getForm()
        ->handleRequest($request);

这很好用，但我想检查两个字段是否都是emtpy，并显示错误。似乎无法解决这个问题。有人可以提供帮助???

Answer 1

最简单的解决方案是根据需要设置两个......

但..在帖子上你可以检查就像

一样简单

if( empty($form->get('name')->getData()) && empty($form->get('dob')->getData())){
   $form->addError(new FormError("fill out both yo"));
   // ... return your view
}else {

  // ... do your persisting stuff
}
...

symfony方式可能会添加自定义验证器我建议你查看custom validator，尤其是part

伪：

namespace My\Bundle\Validator\Constraints;

use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;

class CheckBothValidator extends ConstraintValidator
{
    public function validate($foo, Constraint $constraint)
    {
            if (!($foo->getName() && $foo->getDob()) {
                $this->context->addViolationAt('both', $constraint->message, array(), null);
            }
    }
}

Answer 2

在SELECT * FROM q_products p JOIN ( SELECT productid FROM q_product_apply_access paa WHERE paa.productid = p.productid AND paa.partnerid = 'partnerid' AND paa.apply_status = 0 AND p.visibility = 3 ) paa ON paa.productid = p.productid JOIN ( SELECT productid FROM q_product_aff_access paf WHERE paf.productid = p.productid AND paf.accid = 'accountid' AND p.visibility = 2 ) paf ON paf.productid = p.productid WHERE p.status = 0 AND p.productId IN ( productIdList )文件夹中创建文件名Bundle->Resources->Config 然后

validation.yml

一旦您检查提交的表单数据 isValid（）

，验证就会发挥作用

namespace\YourBundle\Entity\EntityName:
    properties:
        dob://field that you want to put validation on 
            - NotBlank: { message: "Message that you want to display"}
        gender:
            - NotBlank: { message: "Message that you want to display" }

没有类的Symfony2表单构建器检查多个字段是否为空
