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 myscript.php?n=0&n=1 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 checked! NOTE: the order is important! The conditional input must come *after* the default!
