An OO wrapper around the PayPal Checkout API


  1. Create a Checkout object passing in the page and your client id from PayPal.
  2. Use setFunctionJavaScript to specify the JavaScript to be executed for each of the following actions: onCancel, createOrder, onApprove and optionally onError
  3. Create createOrder and onApprove callbacks in PHP according to PayPal docs using the \PHPFUI\PayPal\Order class.
  4. Add the Checkout object to the page where you want it to appear.
