I need to create a PHP script that reads some of the fields of an RSForn and creates a QR code with them. I've been doing a little bit of research and I've found a PHP library that may suite my needs: http://phpqrcode.sourceforge.net/. Now the question is how do I add this library to my current Joomla installation? Then, forms created with RSForms have a place to enter PHP scripts to be executed when processing forms. So I guess this is my game area. Which is the PHP code to get the value of a given field, let's say, Username? I'll keep researching on the subject, but any suggestion or hint will be highly valued.
