Quick & Dirty
If your names not on the list, you're not coming in!
|
my %rules = ( action => qr/^[\w\.\-]+$/ }; foreach my $name ($cgi->param()) { next unless($rules{$name}); my $value = $cgi->param($name); next unless($value =~ $rules{$name}); $cgiparam{$name} = $value; } |
Much better. Now we just expand the rules to include other regular expressions and reference our values by referencing the name in the %cgiparam hash.
To improve on this we could create a configuration file with all our rules and load them dynamically.
