Hello! I frequently develop websites with multi-page forms and need to pass data through the forms efficiently. I developed three routines (below) to do this. My question is: This seems like such a common thing to that either there should also be a solution (that I haven't noticed) such as routines in CGI.pm, or there is a good way to avoid this. Are you all using routines like the ones below? If not, what are you using? 
use CGI qw/:standard/;

# An efficient way to pass param variables on through a page
sub export_form_vars {
    my @input = @_;
    my $html = "\n";
    foreach my $key (@input) {
        my @vars =  param $key;
        foreach my $val (@vars) {
            $val = escapeHTML($val);
            $html .= "<input type=hidden name=\"$key\" value=\"$val\">
+\n"
        }    
    }
    return $html
}

sub export_form_vars_to_query_string {
    my @input = @_;
    my $html;
    foreach my $var (@input) {
        $var = escape($var);
        $html .= '&amp;'."$var=".param($var);
    }
    $html =~ s/^&amp;//;
    return $html
}

sub export_entire_form {
    my $html;
    foreach my $k (param) { 
            my $v = param($k);
            $html .= '<input type=hidden name="'.escapeHTML($k).'" val
+ue="'.escapeHTML($v)."\">\n"    
    }    
    return $html;
}
