New in Symfony 4.3: Improved Financial Constraints

New in Symfony 4.

3: Improved Financial ConstraintsSymfonyBlockedUnblockFollowFollowingJan 3Contributed by  Sylvain Fabre  in #28479.

Matching BIC and IBAN codesThe International Bank Account Number (IBAN) is an internationally agreed system of identifying bank accounts across national borders.

The Bank Identifier Code (BIC) is a unique identification code for both financial and non-financial institutions defined in the ISO 9362 standard.

Although both codes are independent, they can be checked in combination to validate that both belong at least to the same country.

In Symfony 4.

3 we improved the Bic constraint to allow validating BIC and IBAN codes together.

First, you can pass the IBAN code using the new iban option:use SymfonyComponentValidatorConstraints as Assert;// .

public static function loadValidatorMetadata(ClassMetadata $metadata){ $metadata->addPropertyConstraint('businessIdentifierCode', new AssertBic([ 'iban' => 'FR1420041010050500013M02606', )]);}You can also use the new ibanPropertyPath option to define the object property that stores the IBAN code:use SymfonyComponentValidatorConstraints as Assert;// .

class Transaction{ /** * @AssertBic(ibanPropertyPath = "accountNumber") */ protected $businessIdentifierCode; /** * @AssertIban */ protected $accountNumber; // .

}Added support for UATP cardsContributed by  Raúl Fraile  in #29504.

Universal Air Travel Plan (UATP) is the airline owned payment network accepted by thousands of merchants for air, rail, hotel and travel agency payments.

In Symfony 4.

3 we improved the CardScheme constraint to add support for a new UATP scheme:// .

class Transaction{ /** * @AssertCardScheme( * schemes={"AMEX", "MASTERCARD", "UATP", "VISA"}, * message="Your credit card number is invalid.

" * ) */ protected $cardNumber;}.. More details
