Question

Symfony表单允许浮动但没有错误，并且默默地舍入。如果输入值是浮点数，如何引发错误？

我的实体看起来像这样;

use Symfony\Component\Validator\Constraints as Assert;

class Charge
{

    /**
     * @Assert\NotBlank(message="Amount is required.")
     * @Assert\Type(type="int", message="Amount must be an integer.")
     */
    protected $amount;
}

我的表单看起来像这样;

class NewChargeType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->setMethod('POST')
            ->add('amount', Type\IntegerType::class);
    }
}

您可以尝试添加Regex验证，仅需要整数

use Symfony\Component\Validator\Constraints as Assert;

class Charge
{

    /**
     * @Assert\NotBlank(message="Amount is required.")
     * @Assert\Type(type="int", message="Amount must be an integer.")
     * @Assert\Regex("/^-?[0-9]\d*$/", message="Amount must be an integer.")
     */
    protected $amount;
}

在symfony形式中，如何验证parmeter是否为整数，如果它是浮点数则会生成错误？
