Thanks, the first solution works for me.

I didn't get the second solution to work. How do you get it work work given the code I gave about (the %hash and the generate subroutine).

Finally, how would you have set up a template like this?

    Basically your generate subroutine would look like:

    sub generate { my $hashref = shift; my $template = HTML::Template->new(filename => "$tmpldir/generic.tt" +); $template->param(map { defined $hashref->{$_} ? ($_ => $hashref->{$_ +}) : () } keys %$hashref); ); print $template->output; }

    This works because HTML::Template::param expects a list an even number of elements in length suitable for hash type operations, and map of course produces lists, so our expression there utilizes the ternary operator (?:) to test for defined values and outputs key/value pairs.

    I am not really qualified to give advice about template design since I'm new to it myself. But just the fact you're using them I can comfortably say is a good sign :)

      Many thanks, djantzen!

      I like the map code because it's much flexible than having to specify the values to be passed to Template's param().

      It's now working as expected :)
