If you see an error in the browser console that says
Uncaught TypeError: FormNapper requires an HTMLFormElement element or the id string of one.
then the reason is you need an id value on the HTML form tag.
In the code above our form has an
id="credit-card-info"
which the
var form = document.getElementById('credit-card-info');
uses to locate the form, so FormNapper can hijack the submit button and attach the onPaymentMethodReceived callback.
@allella I'm currently trying to do this in a GWT application:
private native void setupCreditCardForm(String domId, String serverToken) /*-{
var form = $doc.getElementById(domId);
braintree.setup(
serverToken,
"custom",
{
id: domId,
hostedFields: {
number: {
selector: "#number"
},
cvv: {
selector: "#cvv"
},
expirationDate: {
selector: "#expiration_date"
}
}
});
}-*/;The var form is correctly fetched but for some reason I'm getting:
braintree-2.27.0.min.js:5 Uncaught TypeError: FormNapper requires an HTMLFormElement element or the id string of one.

This was written when the Braintree Javascript API was version 2 and when the PHP SDK was version 3.8.0. jQuery is also included and used in the code above.
This is using the sandbox environment. In sandbox mode you can use fake/test credit card #'s to trigger different success or failures. Also, note that the $ amount can trigger certain gateway responses, so you have to pay attention to the fake credit card number and amount.
You'll need to install the PHP SDK using Composer for the Braintree_Configuration and Braintree_ClientToken libraries to load/work
https://developers.braintreepayments.com/start/hello-server/php. If you don't use Composer then you'll have to include those classes manually.
When you click the submit button the onPaymentMethodReceived callback will attach a "nonce" value to the hidden input HTML field that has id="nonce" and then immediately submits the form. This allows you to see all your other form elements in the PHP POST array, including the nonce value from Braintree's server.
