    public const KEY_ORDER_ID = 'orderId';

    protected function getValidationRule(string $key): string
    {
        return match ($key) {
            self::KEY_ORDER_ID => '/^[a-f0-9]{42}$/',
            default => parent::getValidationRule($key),
        };
    }

    protected function validateInput(string $key, string $value): bool
    {
        if ($key === self::KEY_LANGUAGE) {
            return $this->validateLanguageCode($value);
        }

        return parent::validateInput($key, $value);
    }

    private function validateLanguageCode(string $value): bool
    {
        if (!in_array($value, ['en', 'it'], true)) {
            throw new UnexpectedValueException('Invalid data.');
        }

        return true;
    }
}

```

### Return page

[](#return-page)

```
// Validate order (get info from storage)
...

/**
 * Special situation: "mac" can be missing from the request.
 * Eg. try to pay already paid transaction.
 * In that situation we don't want to have a transaction error, however we also can not trust the request.
 * Simply do not process transaction.
 */
$processTransaction = true;
try {
    // Try to get mac
    $requestInputService->getValidatedString(RequestInput::MAC);
} catch (OutOfBoundsException) {
    $processTransaction = false;
}

if ($processTransaction) {
    // Validate transaction. Uses input data (_GET or _POST).
    $requestInputService->validateInputMac();

    // Store transaction result.
    ...
}

// Redirect back to website.
...
```
