Plus, even if you use JS you haven't solved the problem for the people
who don't use JS. (Of which I'm sometimes one.)

If you do give them a loop, they can at least decide whether to
iterate it fully, or to use only the "__last__" value and print it. So
there's that. (Not bad for a four- or five-star scale, though it tends
to break down in my case, where I've got threads that nest out to a
couple hundred levels... there's just no simple solution there.)

Well, I'm not "so" concerned (which to me implies some kind of fervour
that I don't think I stated). I was simply asking if there was a way to
iterate through integer values that I couldn't see in the POD - simple
so the designers could decide what to do with the integer - either
iterate from 1 to it, or print it out. Doing it in Perl tends to pre-
suppose one solution over the other. The designers don't really have
problems with loops - they've used H:T and TT, but I don't think they
want to learn Javascript.

Well my problem is that sometimes I want to iterate through a numeric
range. If an article is ranked 4 stars then the designer can either
iterate through each ranking and display a star or he/she can simply
output "4 stars." (one customer likes the latter, another wants the
former). Likewise, I use Data::Page::Navigation for paginated data -
it's a really nice module, and if it displays 10 indexes at the bottom
of the page, say from 5 - 14, it would be nice if I could iterate
through them rather than doing it in Perl. It's not a religious
decision, it just gives the flexibility to the designers.

I hope this gives enough info. If I'm doing it wrong, I'm only too
pleased to be told if there's a better way. Michael Peters suggested
Javascript as one solution, although I'd prefer a solution in H::T if
possible. I have looked through the docs, and couldn't see anything
obvious, but was hoping that perhaps someone had solved this problem
before me via some kind of logic that I hadn't thought of.

If you just want to print 4 stars, then just do that.  * * * *

If you are looking for some indentation background, you could try
something like the following on a div:

    style="background:url('star.gif') right repeat-y;"

If you are looking for something like <TMPL_FOR 1..4> then you probably
need to re-evaluate why you need it - maybe you need to re-think your
original problem.  That said, there have been previous discussions on
whether the TMPL_xxx syntax should support user-defined extensions, and
various people have their own hacks to allow such a feature (which would
then allow you to build your TMPL_FOR).

What is the problem you are trying to solve?  Someone here might have
solved it already...

That would work. It's a shame that there isn't a regular loop construct,
as I'd like a solution for all sorts of loop instances (Looping through
the pagination indexes generated by Data::Page::Navigation for instance)

If you're so concerned about doing it in your Perl code, then I'd do it with
Javascript. Create extra image elements depending on the rating value.

I've been trying to think of a way to do that with CSS, since currently I'd
like to indent things based on a "level" variable passed through the
template (and to complicate things, I'd like to max out at a certain point
to avoid right-margin squish, considering that in a couple of cases the
threads nest over two hundred levels deep).

With (one assumes) a rating system with its own ceiling, though, you could
go with img src="blahblah/star<TMPL_VAR name="rating">.gif" or what have
you, and just have a set of graphics with star1.gif having one star,
star2.gif having two stars, and so forth.

[htmltmpl] Numeric loops

[Dan H. <dan...@re...>]

Hi all

Is there a way to loop from a lower integer to an higher one? For example,
say an article has a rating of 4. I'd like to loop from 1 to 4 and print a
star at each iteration. The only way I can see of doing this is create an
array ref in the perl coder and pass that to the template, which seems a lot
of pointless effort

[htmltmpl] calling javascript from the template

Using HTML::Template

Have placed the Google Analytics code:

</script>
<script type="text/javascript">
_uacct = "UA-xxxxxx-1";
urchintracker();

at the end of my template page just before closing body tag..

It seems the page does not invoke the call to 'urchin.js' as am getting

Is this because the cgi script is loading the page and is therefore 
having trouble invoking the javascript?

This is going to print the result of the build_html... a nice successful 1,
it appears. You might want to test the result, but you probably don't want
to print anything on success.

This is what prints the actual page.

I'm guess that CGI::Ajax is expecting you to return the HTML, not
print it.  So try changing this:

         print Show_Content($pg) if(defined $pg);

To:

         return Show_Content($pg) if(defined $pg);

When you put a print() as the last statement in a subroutine it will
return 1 when it succeeds.

Re: [htmltmpl] Trailing 1

[Barry M. <bmi...@th...>]

You're right, that's not the exact code.  I'm using CGI:Ajax in addition 
to HTML::Template.  At first, I was using strictly CGI:Ajax and doing a 
$template->output; directly at the end of each sub.  But, I wanted to be 
able to work with users that don't have JavaScript enabled or portable 
devices that don't support JS.  Now, I return the $template->output and 
either print it (for AJAX) or assign it to a tmpl_var in the whole page 
template.  Putting it into the page template as a TMPL_VAR doesn't show 
the 1.  Only printing it after an AJAX call.

It does happen with this code (stripped down version of my full script 
to save bandwidth):

#!/usr/bin/perl -w
use strict;
use CGI;
use CGI::Ajax;
use HTML::Template;

my $cgi = new CGI();
my $pjx = new CGI::Ajax('change_page' => \&change_page);

print $pjx->build_html($cgi,\&Show_HTML);

sub change_page {
        my $pg = $cgi->param('page');
        print Show_Content($pg) if(defined $pg);
}

sub Show_HTML {
        my $template = HTML::Template->new(filename => 
"/var/www/localhost/htdocs/perlsite/index.tmpl");
        my $content = '';

        my $content_template = HTML::Template->new(filename => 
"/var/www/localhost/htdocs/perlsite/content/index.html");
        $content = $content_template->output;

        $template->param(content => $content);
        return $template->output;
}

sub Show_Content {
        my $pg = shift;

        my $template = HTML::Template->new(filename => 
"/var/www/localhost/htdocs/perlsite/content/$pg.html")
        return $template->output;
}

That 1 is likely the return value from print().  I don't know how it's
getting printed, but I suspect the code you posted isn't the code
you're running.  I tried it and I didn't get a trailing one.  Are you
using CGI::Application perhaps?

This probably has a very simple solution.  I am returning 
$template->output from a sub and then printing the results.  Every time, 
there's a trailing '1' at the end of the data.  How do I eliminate it?

index.tmpl:
<html>
   <head>
       <title>Hello</title>
   </head>
   <body>
       Hello World!
   </body>
</html>

print Show_HTML();

sub Show_HTML {
   my $template = HTML::Template->new(filename => 'index.tmpl');
   return $template->output;
}

Result:
Hello World!1

Re: [htmltmpl] using HTML::Template with CGI:Ajax

[Dan H. <dan...@re...>]

Hi

Have a look at the CGI::Ajax demo code for "Skips using build_html()"
http://www.perljax.us/demo/pjx_nobuild.txt

As with the example you'll need to include

<div id=3D'__pjxrequest'></div>

in your template. Since your html is in a template you can ignore the
example's "hard-coded" HTML, and simply make sure that you have the
following H::T tag in your HTML <head> section:

<tmpl_var pjx>=20

Set the tag in your Perl code with

$template->param('pjx' =3D> $pjx);=20

Sorry I don't have any concise  examples since I use CGI::Ajax with
CGI::Application and there's a lot of irrelevant stuff, but this should =
work
for you

Re: [htmltmpl] Dot Plugin

[Robert H. <si...@gm...>]

I would be curious on how many HT'ers using the dot plugin and what they 
  think of it as well.

[htmltmpl] Dot Plugin

[Sanjeet G. <sg...@gm...>]

Hello all,

 I am not a very experienced perl programmer and I do not have access to the
server or fancy modperl. Thus, I needed something that I could drop in and
TT kept giving me errors when I tried that. HTML::Template was the only one
that worked for me.

I found the dot plugin on CPAN and began using it as I need hash support
currently not offered in the regular distribution. The package description
said that no attempt to benchmark has been done. My question is how much
slower is this plugin over the regular distribution (even anecdotal evidence
helps).

Prior to HT, I generally used the qq~ ~; in subroutines and I would call the
subroutine if I wanted to use that particular html code section. After
switching to HT, my primitive benchmarking system showed a 0.07s increase in
execution time from ~0.15 to ~0.22.

I really like the system and my code is a lot cleaner now. I tried the file
cache system but I saw no reduction in execution time (does this help w/
server load instead?). The temp files are being generated so it must be
working correctly.

I apologize for my newbie questions ahead of time. Any advice/help is much
appreciated.

Thank you,

expression with just the variable name will fail. For example, both of
these tags fail:

 <tmpl_var expr="foo">
 <tmpl_if expr="foo">Yes</tmpl_if>

This used to work in version 0.04.

We have a workaround in that we can convert to using a name attribute, i.e.,
 <tmpl_var name="foo">
but we have a lot of templates and would like not to modify them.

I looked a little closer at Expr.pm and found a bug in the discovery of
variable names with no operators. The analysis always starts at the second
level of the parse tree. The enclosed one line patch just wraps the test
parse tree in an array while testing so that discovery will bare name
variables. All unit tests pass after applying this. I've also enclosed a
simple test case and template file to demonstrate this bug.

It would be great if this could be folded into the official distribution.
Let me know if you need any additional information about this.

Thanks,
Tim Walters

Re: [htmltmpl] Feature Idea [TMPL_VIRTUAL]

Hi Jason,

Are you simply looking for something like TMPL_INCLUDE ?

Re: [htmltmpl] Feature Idea [TMPL_VIRTUAL]

[Mathew R. <mat...@ne...>]

Hi Jason,

I personally think this is a good idea, especially if it was provided by
a plugin (which means other TMPL_xxx's would also be possible).


In this case probably what you want is to use a TMPL_VAR which contains
the output of a seperate H::T instance, as in:

my $ht = new H::T(filename => "helloworld.tmpl");
my $helloworld = $ht->output();
$ht = new H::T(filename => "index.tmpl");
$ht->param("helloworld" => $helloworld);
$ht->output();

or something like that, ie: generate your virtual's before generating
your output.

Mathew
