VoterInterface

The following example is a voter disabling an offline payment method if the cart contains any virtual products:

final class OfflineVoter implements VoterInterface
{
    public function vote(PaymentMethodInterface $method, CartInterface $cart): bool
    {
        foreach ($cart->getEntries() as $entry) {
            if ($entry->getProduct()->getProductType()->isVirtual()) {
                return false;
            }
        }

        return true;
    }
}

The \Ibexa\Contracts\Payment\PaymentMethod\Voter\VoterInterface implementations must be registered as a service with ibexa.payment.payment_method.voter tag and its type attribute associating the voter to a payment method's identifier.

services:
   App\PaymentMethod\OfflineVoter:
       tags:
            - name: ibexa.payment.payment_method.voter
              type: offline
