Pass from where?
If it's a checkbox on a form, just use isset() to test for the existence of
the variable: true means it's ticked, false means it isn't.
If it's from MySQL I'd suggest using an ENUM('y','n') or a TINYINT
field
instead, but I suppose you could test for things like empty or zero-length
strings.
Cheers
