2.3 新版功能: The Iban constraint was introduced in Symfony 2.3.
This constraint is used to ensure that a bank account number has the proper format of an International Bank Account Number (IBAN). IBAN is an internationally agreed means of identifying bank accounts across national borders with a reduced risk of propagating transcription errors.
| Applies to | property or method |
| Options | |
| Class | Iban |
| Validator | IbanValidator |
To use the Iban validator, simply apply it to a property on an object that will contain an International Bank Account Number.
# src/Acme/SubscriptionBundle/Resources/config/validation.yml
AcmeSubscriptionBundleEntityTransaction:
properties:
bankAccountNumber:
- Iban:
message: This is not a valid International Bank Account Number (IBAN).
// src/Acme/SubscriptionBundle/Entity/Transaction.php
namespace AcmeSubscriptionBundleEntity;
use SymfonyComponentValidatorConstraints as Assert;
class Transaction
{
/**
* @AssertIban(message = "This is not a valid International Bank Account Number (IBAN).")
*/
protected $bankAccountNumber;
}

)));
}
}
type: string default: This is not a valid International Bank Account Number (IBAN).
The default message supplied when the value does not pass the Iban check.
type: mixed default: null
2.6 新版功能: The payload option was introduced in Symfony 2.6.
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to.
For example, you may want to used several error levels to present failed constraint differently in the front-end depending on the severity of the error.
