This is fine for most cases, but let's say that $_POST['var'] *is* set to either an empty string ("") or a string containing zero ("0"). Your test will fail, because both of these are evaluated as FALSE when cast as a boolean.That's the meat of it, then. I wasn't aware of the different types of evaluation that could be done on a variable (boolean, etc). Okay, I'm reading that link as I write this. Thanks again.
