Solution

  • If you want to either enable or disable certain payment methods based on some criteria you can use the payment_method_is_active event.

    In the payment_method_is_active event you have access to 3 parameters:

    • $observer->getEvent()->getData('method_instance), the payment method
    • $observer->getEvent()->getData('quote'), the quote being processed
    • $observer->getEvent()->getData('result'), a data object containing the result

    In the result is_available is defined which is either true if the payment method should be enabled ("available") or false if it should be disabled.

    With these 3 objects you can

    • Determine whether the payment method is the method you want to disable based on some criteria
    • Get the products in the quote and their attributes
    • Result to say whether the payment method should be enabled or not.
    class DisablePaymentMethodBasedOnSomething implements ObserverInterface {
    public function execute($observer) {
        $event = $observer->getEvent();
        $method = $event->getData('method_instance');
        $quote = $event->getData('quote');
        $result = $event->getData('result');

        if (payment method is not cash on delivery) {
            return;
        }

        if (quote does not contain products with gateway attribute) {
            return;
        }

        $result->setData('...', false);
    }
}

    As you see I didn't fill in all the blanks, I hope the example will guide you in the right direction.
