howdy monks!

I'm trying to put together a subclass of the standard CGI module that overrides the param() method to automatically strip HTML out of parameter values. the intention is that the subclass be reverse compatible the the original.

I've got it working pretty good at the moment, but I'm kinda stumped by file upload fields. What I'd like to do is run the HTML strip operation on just the filename and leave the contents of the actual file being upload alone.

I can kinda follow how file uploads are tracked internal to the module, but can't quite figure out how to change the name of file that's been uploaded. The whole blessed filehandle handle thing is blowing my mind.

here's the relevant part of my code so far:

sub param {
  my $self=shift;

  my $returnValue;

  my @v=$self->SUPER::param($_[0]);

  if(ref $v[0] eq 'Fh') {
                
    my $fileName=$v[0]->asString();
                    
    my $strippedFileName=$hs->parse($fileName);
                
    if($fileName eq $strippedFileName) {

      # the filename wasn't changed
      $returnValue=$v[0];

    } else {

      # filename was changed, need to recreate

      # this is where I'm stuck...

      # $self->{$_[0]}=?;
    } else {
      $returnValue=$hs->parse($v[0]);
    }

    return $returnValue;
}

Any suggestions would be greatly appreciated!
