I want to do something like this to check if a variety of submitted
form fields (crn, instructor, etc) have any value in them:
$reqfields = array('crn', 'instructor');
$errorflag = 0;
foreach ($reqfields as $field) {
if ($_REQUEST[$field] == '') {
$errorflag = 1;
}
}
But I can't quite get the syntax right... help??
