You don't need it regardless of tmpl_if or not. die_on_bad_params prevents the
Perl code from passing in vars that don't exist in the template, not the
template from having unused vars.

[htmltmpl] Comments

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

In TT I can create a comment like:

[%# This is a comment %]

The benefit to that is that comment gets stripped out when the template 
is processed (i.e you don't see it if you source the HTML file from the 
browser window).

Is there a way to create a filter in HT that does the same thing?

Where is fruit.tmpl located?  Where is the script that's trying to
access it located?  What does you code look like?  Are you setting the

I would use a relative path, it is a little uncetain which will be the
Apache CWD, in order tu use relative path to it.

You can store a base path in a configuration file or in the Apache config
(using $r->dir_config()) and the construct the template path before each
call to HTML::Template

If they're nested:

first case

<TMPL_IF yadayada>
second case

[htmltmpl] ANNOUNCE: Krang v2.100

[Sam T. <sa...@tr...>]

Krang v2.100 is now available (the source release is up now and binary
builds should be up soon).  Notable changes in this release:

     * Numerous bugs were fixed in Krang's most intensive QA cycle in
       years.

     * Krang now includes methods to integrate with dynamic front-end
       applications by publishing CGI::Application instance scripts and
       templates.  New methods were added to
       Krang::ElementClass::TopLevel to facilitate this:
       publish_frontend_app_template() and publish_frontend_app_stub().
       [Jesse Erlbaum]

     * Modified Site Server configuration to support CGI applications
       and Apache::Registry apps.  This will permit the site server to
       host interactive applications.  [Jesse Erlbaum]

     * Added new parameter "mode" to additional_content_block() method
       in the publisher. This new parameter permits the permission of
       the file to be set, which is particularly useful for publishing
       executable files.  [Jesse Erlbaum]

     * Added new options to Krang::HTMLPager to allow paging of data
       from external sources.  [Michael Peters]

     * Krang now sends no-cache HTTP headers for all Krang::CGI
       requests. This will fix some problems when logging in as a
       different user with the same browser session in IE.
       [Michael Peters]

     * Upgraded to HTML::Template v2.9, fixing several bugs. [Sam]

     * Added a new configuration variable, PreviewSSL, which controls
       whether links to preview use SSL. This behavior was previously the
       default when EnableSSL was set, but now it is available
       independently and can be turned off even when Krang itself is using
       SSL. [Sam]

     * During DB creation, addon SQL files now come after core Krang.
       This allows addons to change existing Krang data/tables.
       [Michael Peters]

     * Stricter enforcement of asset permissions. [Michael Peters]

Detailed change-log here: http://krang.sf.net/docs/changelog.html

Krang is an Open Source web-publisher / content-management system
designed for large-scale magazine-style websites.  It is a 100% Perl
application using Apache/mod_perl and MySQL, as well as numerous CPAN
modules.

Krang provides a powerful and easy to use story and media editing
environment for website editors, as well as a complete template
development environment for web designers. On the back-end, Perl
programmers can customize Krang to control the data entered in the
story editor and add code to drive the templates to build output.
Krang can be enhanced with add-ons containing new skins and other new
features.  Krang easily handles large data sets and can manage
multiple websites in a single installation.

For more information about Krang, visit the Krang website:

    http://krang.sourceforge.net/

There you can download Krang, view screenshots, read documentation,
join our mailing-lists and access the CVS tree.

HTML::Pager was designed to do this for you.  It's a little tricky to
use, but you can study the code if you just want to see an example of
how it's done.

For the database side of things, be sure to use LIMIT and OFFSET to
get your data-set back from MySQL.  Selecting everything like you're
doing now is going to be very slow for large lists.

Nope.  If you're worried about people peeking at your cached templates
just be careful to set the permissions on your cache dir correctly.
It needs to be readable and writable by the CGI process, but it
doesn't need to be accessible by anyone else.

[htmltmpl] resultset Paging and Row limitation

[Massoud K. <mk...@ca...>]

Hi,
I am new to the Html-template and perl.
How can I show the resultset to the web page which Shows 10
records per page and also page numbers on the bottom of the
table?

This is my perl codes;
#!perl

use DBI;
use strict;
use CGI qw/:standard/;
use HTML::Template;

# open the html template
my $template = HTML::Template->new(filename => 'temp.tmpl');


my $username = "mm";
my $password = "kk";
my $dsn = "DBI:mysql:database:localhost";
my $dbh = DBI->connect($dsn,$username,$password)
  or die "Cannot connect to database: $DBI::errstr";

my $search = param('search');

my $sql ="SELECT * FROM database where name like '$search%'
or last like '$search%'"; 

my $sth = $dbh->prepare($sql);

$sth->execute()
    or die "Cannot execute sth: $DBI::errstr";


# a reference to the array of results
my $tbl_ary_ref = $sth->fetchall_arrayref({});
# cleanup
$sth->finish;
$dbh->disconnect;
# assign the reference to the results to a h::t var called
results
$template->param(results => $tbl_ary_ref);
print "Content-Type: text/html\n\n", $template->output();

my 'temp.tmpl' is:



<!-- loop over results -->
<tmpl_loop name=results>

<tr>
<td align="center"><tmpl_var Name=name></a></td>
<td align="center"><tmpl_var name=last></a></td>
</tr>
</tmpl_loop>


Many thanks,

[htmltmpl] ANNOUNCE: HTML::Template v2.9

[Sam T. <sa...@tr...>]

CHANGES
    - New Feature: the force_untaint option makes sure you do not
      pass tainted values to param(). [Sven Neuhaus]

    - New Feature: Added ESCAPE="none" as a synonym for ESCAPE="0".
      Fixed both to work with default_escape. [cp...@pu...]

    - Bug Fix: DEFAULT didn't work with URL and JS escaping.

    - 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.)

    - Doc Fix: Changed references to CVS in the docs to Subversion now
      that the switch is complete.

    - Test Fix: At long last, the work from the Phalanx project has
      been merged!  The tests are now more complete and easier to work
      on.  Thanks Phalanx guys!

DESCRIPTION

     This module attempts to make using HTML templates simple and
     natural. It extends standard HTML with a few new HTML-esque tags -
     <TMPL_VAR>, <TMPL_LOOP>, <TMPL_INCLUDE>, <TMPL_IF>, <TMPL_ELSE>
     and <TMPL_UNLESS>.  The file written with HTML and these new tags
     is called a template. It is usually saved separate from your
     script - possibly even created by someone else! Using this module
     you fill in the values for the variables, loops and branches
     declared in the template. This allows you to separate design - the
     HTML - from the data, which you generate in the Perl script.

     This module is licensed under the same license as Perl. See the
     LICENSE section of the docs for more details.

TUTORIAL

     If you're new to HTML::Template, I suggest you start with the
     introductory article available on the HTML::Template website:

        http://html-template.sourceforge.net

AVAILABILITY

     This module is available on SourceForge.  Download it at:

        http://html-template.sourceforge.net

     The module is also available on CPAN.  You can get it using
     CPAN.pm or go to:

You might look at installing C::A::DevPopup since it will give you some nice
stuff to profile.

Yes. You can't time output() without actually running it. Time the method, save
the results to a scalar, then insert the time into that scalar.

Thanks Michael. Actually, one of the reasons I'm doing this is to
convince the customer to move to CGI::App instead of one huge script.

I considered saving the post output() results elsewhere to review. Is
that what you mean by do it afterwards? I can't think of a good way to
actually include it in the page generated by output.

You'll have to do it afterwards. The way CGI::Application::DevPopUp does this is
by creating a popup HTML, parsing the final HTML and inserting it right before

Hi html-template-users,

I found some problem

I have object $associate (return by 
HTML::Template::Associate::FormValidator) with

'MISSING_FIELDS' => [
   {
     'FIELD_VALUE' => 1,
     'FIELD_NAME' => 'password2'
   },
   {
     'FIELD_VALUE' => 1,
     'FIELD_NAME' => 'login'
   },
   {
     'FIELD_VALUE' => 1,
     'FIELD_NAME' => 'password'
   }
],

in template

<!-- TMPL_IF NAME=MISSING_FIELDS -->
Some fields are missing
<!-- /TMPL_IF -->

load with

associate => [ $q, $associate ]

in logs:

HTML::Template::param() : attempt to set parameter 'missing_fields' with 
an array ref - parameter is not a TMPL_LOOP!

is it bug ?

if I add

<!-- TMPL_LOOP NAME=MISSING_FIELDS -->...

all ok

You can certainly use the template as a reference to a scalar (a
"string"). Search the documentation for "scalarref".
