( #3333=superdoc: print w/replies, xml ) Need Help??

Well - I'm feeling a little confused and even more stupid...
I identified that $ENV{'DOCUMENT_ROOT'} could be the problem and hardcoded them and still came up with the problem. But now I hardcode them again I cannot replicate the problem - in other words, it works!

Here is a working example, in case anyone stumbles along this path as much as anything else

#!/usr/bin/perl -T use strict; use warnings; use CGI::Carp qw(fatalsToBrowser); use FindBin qw($RealBin); my $safepath; BEGIN { if ($RealBin =~ m!^(/home/...path.../(test|uk)/www)!) { $safepath = "$1/../lib"; } else { die "Insecure access!"; } } use lib "$safepath"; use cPanelUserConfig; use PDF::API2; my $pdf = PDF::API2->open("/home/...path.../test/data/xmas/GiftSubscr +iption.pdf"); my $font = $pdf->font("/home/...path.../test/data/xmas/Merriweather.tt +f"); my $page = $pdf->open_page(1); my $text = $page->text; $text->font($font, 36); $text->position(656, 403); $text->text('XXX'); print "Content-type: application/pdf\n\n"; print $pdf->to_string;

I can only assume that I hardcoded one environment variable but not the other but that seems pretty strange. I don't know what I did or didn't do to keep the problem whilst I thought I had got rid of $ENV{'DOCUMENT_ROOT'}.

Now I need to go back to the environment variables and untaint them with some sense checking.

Sorry for a bit of a wild goose chase
I'll go back to watching fireworks...

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
