[htmltmpl] .tmpl page not rendering on screen

From: Brad Cathey <bradford@hi...> - 2004-11-09 20:25

Hello folks,

I've been using HTML::Template a thousand times over the past year and never
had a page just not output.

http://www.cicsnorthtown.org/cgi-bin/facultyadmin.pl?funct=menu

Check the source code and note it just renders "<html><body></body></html>"

If I try: http://www.cicsnorthtown.org/admin/menu.tmpl the page looks fine.

or, in my Perl if I substitute at different file, like "test.tmpl" it works
great.


Perl:

   use HTML::Template;

   my $template;

   $template = HTML::Template->new(filename => '../admin/menu.tmpl');
   $template -> param(facultylist=> $teacherdata );

   print "Content-type: text/html\n\n";
   print $template->output();


H::T is not returning any errors. Could it be a corrupt .tmpl file? If so,
how would I know? 

Thanks.

Actually, it outputs nothing at all.  I bet you're using a Mozilla-based 
browser.  Mozilla puts in those HTML tags automatically when you view the 
source on an empty text/html document.

  My guess is you are getting some kind of fatal Perl error in the one
invocation instance.  Try adding:

  use CGI;
  use CGI::Carp 'fatalsToBrowser';

  at the head of the program and see if you get any output with this. 
(This should send your Perl error messages to the browser, unless
things are so messed up that Perl itself can't load.)

Thanks Clifton, but I have all that debugging stuff in place. In fact, when
I use Data::Dumper I it renders the page along with the hash.

I'd do a hex dump, but I have no idea what I'm looking for. Maybe I should
start rebuilding the .tmpl file line by line and see where it breaks.

Try setting die_on_bad_params to 0 and see what happens, e.g.:
$template = HTML::Template->new(
  filename => '../admin/menu.tmpl',
  die_on_bad_params => 0,
);

What happens when you run it from the command-line?

When you say that H::T is not returning any errors are you looking in
Apache's error_log to verify?
