In the form examples throughout the book you recommend combining the form and validation and checking to see if the form has been submitted by using - if ($_SERVER['REQUEST_METHOD'] == 'POST')
When I try that I get error messages telling me that the variables haven't been defined yet. That's because the form hasn't been submitted yet!
I thought you said that the server function would just be empty if there was nothing to request (ie. before submission)? Am I missing something?
