HTML::Template Isn't Working

by rjahrman (Scribe)
on Aug 05, 2004 at 23:46 UTC ( [id://380414]=perlquestion: print w/replies, xml ) Need Help??

rjahrman has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to use HTML::Template in my script. I have wdi.tmpl in the same folder as my script, and I use these lines:

my $template = HTML::Template->new(filename => 'wdi.tmpl');
# Later...
$template->param(DIRLINKS => "1");
$template->param(CONTENT => "2");
# At the end...
$template->output();

[download]

However, no matter what I do I only get a blank page. I viewed the source and it looks like it's just a standard 'blank page' line. What am I doing wrong?

Edited by davido: Added code tags and fixed HTML.

    Try 

      print $template->output();

    Also, you'll need to ensure that you print a valid HTTP response header first. 

      print "Content-type: text/html\n\n";

    will do.

    Greetings rjahrman,

    To follow-up on what dws wrote, yes, you want to use print for the output if you're using HTML::Template alone. If you're using H::T along with something like CGI::Application, you may (depending on WWYWTDI) want to return the output instead of print.

    Good luck.
