Simple case - let's just have a text field.

Obviously we can use Spry to say "Fill out your school name, dumkopff"  
- but if they have JacaScript turned off or you forgot, then we should  
test for the existence of the value on the handling page. Long version  
of the check:

session_start();
$_SESSION['error'] = "";
if (isset($_POST['school']) $$ $_POST['school'] != "") {
	echo "All is well";
	//Do all our normal stuff
} else {
	$_SESSION['error'] = "No school name";
	header['Location: input.php'];
}

And check for the existence of the session variable and echo it out to  
the page if required...
