I want to know how to get two parameters from URL. I have a url like this: www.example.com/simplepay-cancel/?r=eyJyIjo1MDE3LCJ0Ijo1MDIyOTI5NTIsImUiOiJDQU5DRUwiLCJtIjoiT01TNTMxNDU1MDEiLCJvIjoiMTE2Njk4ODAyOTk1NjMwIn0=&s=h/kKbYJWL3EYZiW/fG xaUh Ekx3d7E0EGBCieMGUjWlT+9tUhKBDJU4JglMVpYloj

It contains two parameters:rands. Both are encrypted.

I want to get the following:

if ( (isset($_GET['r']) && isset($_GET['s']))) { echo 'Hello'; }

It only works if I set therparameter to a URL. This is a Wp site and I set the id assparameter and it fails and goes to 404 page.

How to get these two parameters?

Thanks!
