Hi,
I do have warning, strict all that turned on, but someone here don't like to see in the error logs the use of unnitialized errors on it, this sub checks the input from a form like this, simply:
my $test = filter(param( 'name' ));

I still think that a sub like that shouldn't offer anymore options other than check for bad characters trying to make into the application.
