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?

Thanks,
Arnie

Like Jonathon said, it's hard to know without seeing more code, but unless a form is properly submitted, the if ($_SERVER['REQUEST_METHOD'] == 'POST') statement you provided will always evaluate to false.

I'd like to see the actual error message and the details about the installation. $_SERVER['REQUEST_METHOD'] should always be set, because the page is being requested somehow (either via GET or POST).
