How to display only certain fields during dynamic HTML generation?

jfsully has asked for the wisdom of the Perl Monks concerning the following question:

I'm sure this is a newbie question that you can answer in your sleep but,

Using an HTML online form, I would like to control which fields are displayed to the user upon display of the success_page.

I think the code that needs tweaking is:

-------------------------------------

=item success_page_fields ()

Outputs success page HTML output for each input field.

=cut

sub success_page_fields {
  my ($self) = @_;

  foreach my $f (@{ $self->{Field_Order} }) {
    my $val = (defined $self->{Form}{$f} ? $self->{Form}{$f} : '');
    $self->success_page_field( $self->escape_html($f), $self->escape_h
+tml($val) );
  }
}

-------------------------------------

Any help would be GREATLY appreciated!

First choose the fields you are interested in: `my %fields_to_show = map { $_ => 1 } qw/field1 field2 field3/;` [download] now modify your loop to skip fields you don't want: `foreach my $f (@{ $self->{Field_Order} }) { next unless exists $fields_to_show{$f}; my $val = (defined $self->{Form}{$f} ? $self->{Form}{$f} : ''); $self->success_page_field( $self->escape_html($f), $self->escape_html($val) ); }` [download]	[reply] [d/l] [select]

I could be wrong, but it looks like you can edit the list of fields to display by changing $self->{Field_Order}. For instance, if you're calling success_page_fields() as follows: `success_page_fields($hashp);` [download] You can edit the list of fields with the following: `$hashp->{'Field_Order'} = ['field1', 'field2', 'etc']; success_page_fields($hashp);` [download]	[reply] [d/l] [select]

I would like to control which fields are displayed to the user upon display of the success_page. This is a problem that templates are ideally suited to handle. Using HTML::Template, for example, a template to handle static {name, value} pairs might look something like `<TMPL_IF foo>foo: <TMPL_VAR foo ESCAPE=HTML><br /></TMPL_IF>` [download] It's only slightly more complicated to handle dynamic {name, value} pairs. `<TMPL_LOOP vars> <TMPL_IF value><TMPL_VAR name ESCAPE=HTML>: <TMPL_VAR value ESCAPE=HTML><br /></TMPL_VAR> </TMPL_LOOP>` [download] A Super Search for "HTML::Template" will turn up lots of examples to show how to set this up in code.
