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

Hi,

I am using Template Toolkit to seperate my html code with perl script, but I face problem when running the perl script on web browser or user other than root showing error "Failed to execute the template toolkit" But when i run as root in the command line I am getting the correct output

Can you suggest me a solution

Below is my script 
#!/usr/bin/perl -w
use strict;
use CGI qw(:standard);
use Template;
use 5.010;
use Data::Dumper;
print "Content-Type: text/html\n\n";

#$| = 1;

#----------------------------------------------------------
#            Define Varriables 
#----------------------------------------------------------
#.....................................................................

my $template = '/var/www/linen_tracking/home.html';
say "hello ";

my $hell = "romy";

my $vars = {
    HELL => $hell,
    };


#.....................................................................

#.....................................................................
+...................
#                Template Presentation                    
#.....................................................................

my $tt = Template->new ({
    INCLUDE_PATH => [
                '/var/www/e-commerce/template/src/',
                '/var/www/e-commerce/template/lib/',
            ],
    PRE_PROCESS => 'config',
    PRE_PROCESS => 'variable',
    ABSOLUTE    => 1,
    RELATIVE    => 1,
});


$tt->process($template,$vars)|| die "Failed to execute the template $t
+t->error() \n";

Re: Template Toolkit Root Permission

    The way that this runs only as root leads me to think that some of the directories you are using don't have read permissions for people other than root, making root the only one who can get any output from the shell. So just add read permissions for all in the directories and files used in your script.

      I could see this script actually is exectuing because it could print hello while exectuing the script but the template part not able to show its output you could see the script executing on

      http://182.18.173.61/cgi-bin/linen_tracking.pl

      I have given complete permission to all the directory

      For E.g if i comment the line #PRE_PROCESS => 'config', #PRE_PROCESS => 'variable', It give me complete output as 
      hello 
<html> 
    <head> 
    </head> 
    <body> 
    
        <h1>romy</h1> 
    </body> 
</html>

      else it give me output as only "hello"

        If you check the Template Toolkit manual, you'll notice:

        Multiple templates may be specified as a reference to a list. Each is processed in the order defined.

        my $template = Template->new({
    PRE_PROCESS  => [ 'config', 'header' ],
    POST_PROCESS => 'footer',
};

        [download]

        and

        Alternately, multiple template may be specified as a single string, delimited by ':'. This delimiter string can be changed via the DELIMITER option.

        my $template = Template->new({
    PRE_PROCESS  => 'config:header',
    POST_PROCESS => 'footer',
};

        [download]

        So, judging by your issue and the way that you have set multiple PRE_PROCESS templates, I think this will fix your problem.

    It may also have to do with write permissions on some temp directory if TT is trying to write precompiled templates somewhere. See the docs on COMPILE_DIR.
