使用Braintree插入式用户界面选择定期结算的付款方式 - 或：查找paymentMethodNonce的付款方式

Question

I'm building a simple payment system using Braintree payments, PHP and JavaScript. I'm using Braintree's Drop-in UI, and would like to create subscriptions (ie recurring billing).

For this, I'm using:

// $_customer is a Braintree_Customer object; a customer stored in the Vault
$subscription_create = Braintree_Subscription::create([
  'id' => $_customer->id,
  'planId' => 'some_package',
  'paymentMethodToken' => $_customer->defaultPaymentMethod()->token
]);

This works fine, and creates a subscription using the customer's 'default payment method'. However, I don't see any way for the customer to change his default payment method. There does not seem to be an option for this in the drop-in UI.

Does this mean I cannot use the drop-in UI for recurring billing? Should I write my own UI to allow customers to change their default payment method?

There is a way to make a payment method the default one. I could use that one, however, I only receive a paymentMethodNonce from the client. How do I find the paymentMethod linked to that nonce?

_{I work at Braintree. If you have more questions, you can always get in touch with our support team .}

You don't need a special method for this, you can pass the nonce directly to Braintree_PaymentMethod::create :

$result = Braintree_PaymentMethod::create(array(
    'customerId' => '12345',
    'paymentMethodNonce' => 'nonce-from-the-client'
));
