CGI::Untaint::object - base class for Input Handlers
package MyUntaint::foo; use base 'CGI::Untaint::object'; sub _untaint_re { return qr/$your_regex/; } sub is_valid { my $self = shift; return is_ok($self->value); } 1;
This is the base class that all Untaint objects should inherit from.
Your subclass should either provide a regular expression in _untaint_re (and yes, I should really make this public), or an entire is_valid method.
This should really have been two methods, but too many other modules now rely on the fact that this does double duty. As an accessor, this is the 'raw' value. As a mutator it's the extracted one.
Regular expressions to match anything, or nothing, untained. These should only be used if you have already validated your entry in some way that means you completely trust the data.
Are we clean yet?
