title: Add address requirement on PayPal Donate button
body: <p>I am looking to add a Donate button to my website, however the address of the person who donated must be a required field. Looking through the documentation there is the option to pass through extra button variables based on this <a href="https://developer.paypal.com/docs/paypal-payments-standard/integration-guide/Appx-websitestandard-htmlvariables/" rel="nofollow noreferrer">link</a></p>
  
  <p>It seems like the <code>address_override</code> parameter is the only variable that applies. Even then adding this does not make the address a required field. </p>
