Hello

Occassionally I run into a problem space where a good solution is to pass information though CGI-based webpages in hidden form fields. (No, not sensitive info. :). I have a feeling that CGI.pm probably has some tricks to help with this, but I can't find them. Here's some code I've used before as my own helper function: 

sub export_form_vars {
        my @input = @_;
        my $html = "\n";
        foreach my $key (@input) {
                my @vars =  param $key;
                foreach my $val (@vars) {
                        $val = escapeHTML($val);
                        $html .=  qq { <input type=hidden name="$key" 
+value="$val">\n };
                }       
        }
        return $html
}

For each of the field names passed in, it produces the appropriate hidden tags, based on the values in param().

Is there an easy way to accomplish the same thing with CGI.pm? Thanks,
