Hello,
I am trying to perform an inner/outer loop with global_vars set, as shown
in the H:T man page:
# test.tmpl - from the man page ----------
<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>
# test.pl ------------------
#!/usr/bin/perl -w
use strict;
use HTML::Template 2.9;
my $template = HTML::Template->new(
filename => 'test.tmpl',
die_on_bad_params => 1,
loop_context_vars => 1,
global_vars => 1,
);
$template->param(
OUTER_LOOP => [
{ OUTER_VAR => 'I AM THE OUTER VAR' },
{ INNER_LOOP => [
{ INNER_VAR => 'I AM THE
INNER VAR' },
]
},
],
);
print $template->output;
This processes, but outputs:
----
OUTER: I AM THE OUTER VAR
OUTER:
INNER: I AM THE INNER VAR
INSIDE OUT:
----
I suppose thats somewhat close to what I would expect, except that the
outer_var is not available inside the inner_loop. I was also a little bit
surprised that the inner_loop was iterated over by the outer loop, resulting
in two 'OUTER:' outputs - but when I think about it I suppose that could be
considered correct, although slightly odd IMO.
So I tweaked my code to something simpler that seemed like it should work:
#!/usr/bin/perl -w
use strict;
use HTML::Template 2.9;
$template = HTML::Template->new(
filename => 'test.tmpl',
die_on_bad_params => 1,
loop_context_vars => 1,
global_vars => 1,
);
$template->param(
OUTER_LOOP => [ { OUTER_VAR => 'I AM THE OUTER VAR' } ],
INNER_LOOP => [ { INNER_VAR => 'I AM THE INNER VAR' } ],
);
print $template->output;
Just two simple loops for use in the template. But this one dies with:
HTML::Template : Attempt to set nonexistent parameter 'inner_loop' - this
parameter name doesn't match any declarations in the template file :
(die_on_bad_params => 1) at test.pl line 42
I'm surprised I cannot get the man page example to work correctly. Does anyone
have any ideas on this?
Thanks,
Alex
P.S - My next step involves something like this:
<TMPL_LOOP OUTER_LOOP>
<TMPL_LOOP INNER_LOOP>
INNER: <TMPL_VAR INNER_VAR>
INSIDE OUT: <TMPL_VAR OUTER_VAR>
</TMPL_LOOP>
</TMPL_LOOP>
where all the outer_loop vars are actually used in the inner_loop, and never
used in the outer_loop. This specific functionality is fixed in version 2.9
according to the changelog:
http://search.cpan.org/src/SAMTREGAR/HTML-Template-2.9/Changes
- Bug Fix: Long-standing bug where variables set in a loop weren't
available inside inner loops under global_vars if the variable
wasn't actually used in the outer loop. (Thanks to Richard Fein
for help debugging the fix.)
