yeah, but not if two variables share the same name.  I'd like to be able 
to separately specify which loop's var I want.

Isn't that the way it is done in perl? You can only access vars in the
current loop, enclosing loops, and the global scope.

tmpl_include was probably the first thing implemented.  loops within 
loops existed, but weren't documented, so people thought they didn't 
exist.  That's been corrected through the online tutorial.

I really feel that it should be done some other way - with some kind of
namespaces or something similar to DOM objects.  HTML designers are
already familiar with the document.myform.txtName.value syntax, don't
think they'd mind a document.loop1.loop2.var1 style syntax.

Advantage is that you can access a global var from any level of the
loop.  An imposed restriction could be that only elements from the
current loop stack can be called, ie, you can't access vars across
loops, only upwards from the current location.

Thoughts?

Hi Philip,

I probably wouldn't use it without the global_vars option. I use the
global_vars option all the time, it's too useful to be without.

well, apart from die_on_bad_params, global_vars and cache stuff, I'm
pretty certain that HTML.Template.java supports everything that
HTML::Template does and nothing more ;)  die_on_bad_params I should have
soon, global vars I probably won't, and I'd like to hear people's

cache stuff I don't know how to, so if someone wants to volunteer help, 
I'll be most delighted :P

Almost certainly not, but the only way to find out is to test!  See the

Have you through about using something like PageKit?:

    http://www.pagekit.org/

PageKit uses HTML::Template to control every page, and XML on the back-end
to provide data.  I would imagine that something like this could be used to
do what you have described.  (I've never used PageKit before.)

[htmltmpl] [Announce] ver 0.1.0 of HTML.Template.java released

[Philip S T. <phi...@gm...>]

Version 0.1.0 of HTML.Template.java has just been released.  It's still 
a development release, but is getting stable.  A few bug fixes, and 
enhancements.  Also added the Filter interface.

Following is the ChangeLog

ver 0.1.0

- supports Hashtable style constructor parameter
- Now also accepts Booleans and Integers in constructor parameters, not just
  Strings
- path parameter accepts a single String as well as an array of Strings
- setParam also accepts int, boolean, Integer and Boolean
- added Filter interface
- fixed bug that prevented file handle from working (thanks to Marcos Ramirez)
- fixed case bug with include filenames

Thanx Roger!  I got that to work and once I saw how that worked, I figured

RE: [htmltmpl] using H-T for every page

[Todd S. <zo...@pa...>]

Hi Andrew,

If you use the GET method for your script, the users will be able to book
mark pages and most search engines should be able to crawl through your
site. You can set up Apache to redirect to a script.  For instance you could
have /index.html redirect to your script.  Then the script would look at the
URL requested to build the appropriate page.  That way users could book mark
pages and search engines could crawl your site and none would be the wiser.

H::T is a great module that will work great for your project.

Good luck,

Todd

Subject: [htmltmpl] using H-T for every page


Hello,

I have been using H-T mostly for user interfaces to databases where
users make queries via HTML forms sent to H-T scripts which return
results. Works great (thanks Sam!).

Now I am looking to build an entire site using H-T. All pages will
contain content from the database and be generated from templates. Since
I haven't used H-T this way before, I have some questions.

Would requests for domain.com and/or domain.com/index.html be redirected
to domain.com/scriptname right in Apache?

I assume all links and pages will be domain.com/scriptname+params rather
than domain.com/page.html. I'm wondering how this affects things like
search engine indexing, users bookmarking pages, providing links to
areas within the site. It seems like all pages will have kind of a funky
URL.

I would appreciate comments on the above from those who have more
experience. Also any other comments on the architecture of a project
like this are appreciated.

Thank you,
Andrew

RE: [htmltmpl] using H-T for every page

[Kenny S. <ke...@jo...>]

Hi Andrew,

I do exactly what you are talking about, so that I can use the same
nav/header include and have it dynamically generated each time.

I use apache with mod_rewrite (a standard mod), and I setup a rule that any
request for http://www.journalscape.com/something.html gets sent to
http://www.journalscape.com/js.mod_perl with $ENV{'PAGE'} = something.html

The URL in the browser doesn't change, so they are none the wiser, and I get
the flexibility of H::T.

This is the rule that I use to grab only html in the webroot of the site:

RewriteRule ^/([^/^.]+\.html)$ /path/js.mod_perl [E=PAGE:$1,L]

Check the documentation for DBI. selectall_arrayref expects an actual
SQL statement (text) as its argument, not a statement handle. I suggest
you use fetchrow_arrayref or fetchall_arrayref. The output from the
latter is the same as from selectall_arrayref, but you get to use 
cacheing, placeholders, and so on, as normal.

[htmltmpl] [bug?] odd number of elements in 'new' method call...

[simran <si...@cs...>]

Hi All, 

In HTML::Template verison 2.5 i noticed the following code: 

##### LINE 932 +++
=======================================================================
  # load in options supplied to new()
  for (my $x = 0; $x <= $#_; $x += 2) {
    defined($_[($x + 1)]) or croak("HTML::Template->new() called with
odd number of option parameters - should be of the form option =>
value");
    $options->{lc($_[$x])} = $_[($x + 1)];
  }
=======================================================================

Now i am calling HTML::Template with parameters such as:

  my $class = shift;

  $a = new HTML::Template(
                     filename        => $filename, 
                     other_parameter => (ref($class) ? $class : undef)
  );

This is causing the issue whereby because the for loop above (in the
code) is checking for the "defined-ness" of the "value" (which in some
cases for me is not defined) - it croaks... however, it is valid to have
a has with a defined key but an undefined value, so i am not really
passing the new method an "odd number of parameters".

We can of course check how many elements were passed (including undef
values) by doing something like: 

  croak "Odd number of parameters" if ($#_ % 2 == 0);

  or even 

  croak "Odd number of parameters" if (scalar @_ % 2 != 0);


I haven't provided a patch as its only a one line partial change. Also,
i can't see any of the current scripts breaking by doing it in the
method listed just above. 

What say ye Sam? 

simran.

Howdy!
 
I am having a small problem using DBI and HTML::Pager and was wondering if
somebody could tell me where I am going wrong.  First, I'll state that I
have normally used "fetchrow_array" with H-T and had no problems. I read

this - future ref.

That would work, but I'd rather stay away from include files.  I'm
really hoping to keep all the content and markup in the database, where
I can retrieve it and send it as a scalarref... the fewer separate
places content is located, the cleaner and the better.
