Nice examples of the benefits of HTML::FillInForm. I avoided it for years because it seemed like yet another module to kee up with; it's now a priority.

At any rate, I was trying to figure out how to get it to repopulate checkbox groups with multiple values. For some reason, you must use the fdat parameter and pass in a hash reference instead of doing the fobject parameter.

For example, to process the following code:

<input value="1" type="checkbox" checked name="need_id"> Advocacy
<input value="2" type="checkbox" checked name="need_id"> Domestic Viol
+ence
<input value="3" type="checkbox" checked name="need_id">Racial Diversi
+ty

You would use something like the following:

my %fdat = $q->Vars;
my $html = <output from favorite flavor of templating language>
my $fif = new HTML::FillInForm;
$html = $fif->fill(scalarref => \$html,
                    fdat => \%fdat);

Now sit back and let this module do even more of the busy work for you!
