I believe any element gets submitted unless it is set to disabled,
IIRC (if I am wrong someone correct me, going from memory). Note the
'hidden' form element doesn't show up but submits its name/value

You could check the field for a value, which would at least tell you
something is there other than blank. I think the rest depends on your
server side/cgi processing...
