[thelist] field checking in PHP

I'm using PHP to write a form that puts data into a MySQL database. This
one form is part of a larger registration process.
In this case, none of the fields are required (i.e., the user doesn't need
to fill anything out), but if one field is filled out, they all have to be.
In a two field form, in order to make sure that the fields are filled out
properly, I've done this:
if (($level && !$major) || ($major && !$level)) {
*return an error*
}
The problem is that I need to do the same thing with a 13 field form; as
you can probably imagine, using the approach above will get unwieldy in a
big, big hurry. Does any one know of a better way of checking to make sure
that if one field is filled out, they all are?
Thanks,
Noah
