Does anybody here have experiencing setting up hashcash.io on a non-CMS site?
https://hashcash.io/ (See option 3 at the bottom.)
I can get the client side to work, but I have no idea where to put that PHP.
I did tweet the hashcash.io team, stating that I wasn't sure where the PHP went; their response was that there was "proof of concept on the webpage". I need something a little more explicit.
I have tried incorporating it into the same document as the contact form is on; all I get is a "Notice: Undefined index: hashcashid" notice, and no padlock.
Any ideas or pointers would be greatly welcome.
