process lists of array_refs with Template-Toolkit

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

i want to know if it is in general possible to process lists ofarray_refs with Template-Toolkit.
i have a sub, returning

  return( $sth->fetchall_arrayref);
[download]

this should now be processed via Template-Toolkit. but how can this be done? i have a sub

my $t=Fs2::DBrequest::search_pl_entries(1,1,"a");
[download]

i tried


## first try
##########################################


  if ($c{a} eq "c_searchtest")
  {
    $vars = { search            => $f
    };
  }



##########################################
## second try

my @f = @$t;
  if ($c{a} eq "c_searchtest")
  {
    $vars = { search            => $t
    };
  }




## and in the template
[% FOREACH foo = f  %]

<pre>
START THE OUTPUT
[% foo.0 %]
[% foo.1 %]

</pre>
[% END %]
##
[download]

but none of the 2 are working. and besides, Template-Toolkit does not output errors, so i don't know what's the story... is it possible to process arrays of array, hashes of arrays, lists of array_refs with Template?

any suggestions or examples out there?

thanks
parasew

UPDATE: I just got an email from the Template-Toolkit mailing list - please announce the other forums where you have asked your question in the future. It's just good Netiquette. Another example: `use strict; use warnings; use Template; my $tt2 = Template->new; $tt2->process(\*DATA, { AoA => [ [0,1],[2,3],[4,5] ], AoH => [ {a=>'b'},{c=>'d'} ], }); __DATA__ AoA: [% FOREACH outer_a = AoA -%] [% FOREACH inner_a = outer_a -%] [% inner_a %] [% END -%] [% END -%] AoH: [% FOREACH outer_h = AoH -%] [% FOREACH key = outer_h.keys.sort -%] [% key %] => [% outer_h.$key %] [% END -%] [% END -%]` [download] jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply] [d/l]

Example: `#!/usr/bin/perl -wl use strict; use Template; my $template = <<'END_OF_TEMP'; [% FOREACH foo = f %] <pre> START THE OUTPUT [% foo.0 %] [% foo.1 %] </pre> [% END %] END_OF_TEMP my $tt2 = Template->new(); my $vars = { f => [ [ qw(0 1) ] ] # array of arrays }; $tt2->process(\$template,$vars);` [download] Hope this helps. antirice The first rule of Perl club is - use Perl The ith rule of Perl club is - follow rule i - 1 for i > 1	[reply] [d/l]
