Hi jesuashok, "Is there a way to use TMPL_LOOP inside another TMPL_LOOP Example" This is covered in the HTML::Template documentation, it covers inner and outer loops. I am not sure exactly what thoughts you are looking for, other than you should read the documentation and give loops names. `<TMPL_LOOP OUTER_LOOP> OUTER: <TMPL_VAR OUTER_VAR> <TMPL_LOOP INNER_LOOP> INNER: <TMPL_VAR INNER_VAR> INSIDE OUT: <TMPL_VAR OUTER_VAR> </TMPL_LOOP> </TMPL_LOOP>` [download] Update: You could also check out HTML::Template Tutorial by jeffa from the Tutorials section of the site. Hope this helps. Martin	[reply] [d/l]

Hi, here my sample.. My template like this `<select> <tmpl_loop loop_one> <option name='<tmpl_var name>'> <tmpl_var value> </option> <tmpl_if loop_two> <tmpl_loop loop_two> <option name='<tmpl_var name_one>'> <tmpl_var value_one> </option> </tmpl_loop> </tmpl_if> </tmpl_loop> </select>` [download] My prg is like this `my (@loop_two,@loop_one); for(@arr_name) { push @loop_two, { name_one => 1, value_one => 2 }; } for(@arr_one) { push @loop_one, { name => 1, value => 2, loop_two => \@loop_two }; } $html->param(loop_one => \@loop_one); return $html->output(); where $html is HTML::Template object.` [download] -kulls	[reply] [d/l] [select]

`#test.pl: use HTML::Template; my $tmpl = HTML::Template->new(filename => 'test.tmpl'); $tmpl->param( Loop1 => [ { Loop2 => [ {name => "me"}, {name=>"another"} ] }, { Loop2 => [ {name => "you" } ] }, ]); print $tmpl->output(); # and test.tmpl. <!-- TMPL_LOOP NAME=Loop1 --> <!-- TMPL_LOOP NAME=Loop2 --> <!--TMPL_VAR NAME = name --> <!--/TMPL_LOOP --> <!--/TMPL_LOOP -->` [download] "We all agree on the necessity of compromise.

Yes. Loops inside another loop is no problem for H:T. Boris	[reply]

If you are wanting to loop over something in a completely separate array on each iteration of another array, you will need to enable globals. HTML::Template otherwise masks external variables from the guts of each <TMPL_LOOP>. We have run into problems with this if the variables use the same names or even the same keys, so be careful. You can turn on globals with an option passed into the new() method: `global_vars => 1`	[reply] [d/l]
