I have changed the script to:
sub show_template #parse it right now
{
my $template_file = shift;
my $vars_hashref = shift ;
my $tt;
print "in show_template 1<br>";
$tt = Template->new({
INCLUDE_PATH => ["$root/cgi-bin"],
INTERPOLATE => 1,
}) || do{ print "inside error" ; } ;
print "in show_template 2<br>";
$tt->process($template_file, $vars_hashref) ;
}
at the beginning of the file:
#!/usr/bin/perl
use strict;
use Template;
use CGI::Carp qw(fatalsToBrowser);
use diagnostics;
$|=1;
and the calling for the subroutine is:
eval{
&show_template("some_template.html",$vartoparse);
};
if ($@) {
if (UNIVERSAL::isa($@, "Template::Exception")) {
## error came from Template or below
if ([EMAIL PROTECTED]>type eq "undef") { # yes, the letters u n d e f!
print "error1"[EMAIL PROTECTED]>info; # the error from below Template
(perl
code plugins)
} else {
## the error came from a Template step, do what you want
print "error2" . "$@"; # stringifies the Template error
}
} else {
## the error came from above Template (something else in the eval)
print "error3". $@; # throw it again
}
}
But the output from the xx.cgi is just:
in show_template 1
without any other out put. even the eval doesn't capture the error.... There
is no error at the server's errorlog either.
