The functions in the validating_fns.php do not access the $errors array
you defined in your main script; they access their own local variable by
the same name.
Either declare the $errors array global inside each function or pass it
as a parameter (I like this better)
/* declare $errors global */
function checkFirstName( $firstName ) {
global $errors;
if (empty($firstName)) {
$errors['first_name'] = 'Please enter your first name.';
}
}
/* pass $errors as a parameter (by reference, so that it can be changed) */
function checkLastName( $lastName, &$errors ) {
if (empty($lastName)) {
$errors['last_name'] = 'Please enter your last name.';
}
}
