First, using single quotes does not allow interpolation. You need double quotes.
Second, a
checkbox will shouldn't have any value sent over if not checked. Therefore, what you
can do is
this:
my $check = param( $k );
if ( defined $check ) {
# do something
}
Of course, that's simplified. In reality, you'll want to validate that the data is in
a format
that you expected. It's very easy for a malicious user to change. See 'perldoc
perlsec' for
details on using taint checking to protect your data.
