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!
