Thread: [htmltmpl] Templates with template loops within templates

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi,

Great subject line huh? :)

Ok we have a template.
Inside that template we load in from a database a template with its own 
vars which makes use of a template loop.
In that second template we have a var called URL_BASE which is the base 
path. It works inside the second template, except for within the template 
loop output.

So imagine we already have template object: $template (it by the way has a 
var called URL_BASE also that I thought would be passed down to this inside 
template as well)

my $shipping_temp = 
$config->getShipping_temp($self->param('DEFAULT_PRODUCT')); ## returns 
array ref
my $ship_list_hash = $config->getShipping_list($instance,$dom_int);

$template->param(SHIPPING => '1'); ## part of the top level template

my $shipref = \$shipping_temp->[0];

my $ship_html = HTML::Template->new( scalarref => $shipref,
                                        die_on_bad_params =>0);
my @loop_values = ();
my $num_options = keys(%$ship_list_hash);

         foreach my $key( keys(%$ship_list_hash) ){

           my %inside_hash = ('S_ICON'      => 
$ship_list_hash->{$key}{'courier_icon_url'},
                'S_COURIER'   => $ship_list_hash->{$key}{'courier_name'},
                 'S_METHOD'    => $ship_list_hash->{$key}{'courier_method'} ,
                 'S_METHOD_ID' => $ship_list_hash->{$key}{'ship_method_id'},
                 'S_COST'      => 
$ship_list_hash->{$key}{'shipping_cost'} 

                    );

           if ($shipping_temp->[1] eq 
$ship_list_hash->{$key}{'ship_method_id'}){
                 $inside_hash{'DEFAULT'} = 'Checked';
           }

           if ($num_options < 2){
                 $inside_hash{'DEFAULT'} = 'Checked';
           }

           push(@loop_values,\%inside_hash);

}
         $ship_html->param(URL_BASE      => $self->param('URL_BASE'));   ## 
the problem var
         $ship_html->param(SHIP_LOOP => \@loop_values);

         my $tmpout = $ship_html->output();

Below is the raw HTML output produced, notice the spacer.gif has a full url 
where the ups_2D.gif which comes from the loop does not.

I was a little confused to start off with because I thought the presence of 
the URL_BASE in the second template would be parsed as a result of being 
set in the original top level template. So not only does that not seem to 
be happening, but also when setting the var again in the second template it 
is not working inside the template loop. So my first question, is this the 
way HTML::Template should be working? I didn't expect this problem. The 
next question of course is how can I get this var to be parsed inside the 
loop?

Using the current versions of both HTML::Template and CGI::Application

Please let me know if this is enough info or too much, I wanted to give as 
much detail as I could because I found it hard to explain what I am doing 
with just words.

Thanks,

Eric
