You can take advantage of the way PHP parses passed values...

If you have two (or more) form inputs with the same name, the last value
over-writes the previous one(s).  ie if your script is called like
then you get
  $_GET["n"] == 1

Sure, you say, but how can I make use of that?

Well, if the last value weren't sent, you would still have the previous
value, ie $_GET["n"] == 0

Try this:

    <input type=hidden name=n value=0>        // this value is *always* sent
    <input type=checkbox name=n value=1>    // this value is only sent if

NOTE:  the order is important!  The conditional input must come *after*
the default!
