Checking If Form Has Been Submitted

Recommended Posts

Great book.


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?
