Re: Perl CGI Text box

Ok,
Essentially I am trying to read a file into an array, and
then display the contents of the array inside the text box.
My eventual goal is to display XML text from a file in the text area.
here is the code I am using:

#!/usr/bin/perl -T
use strict;
use warnings;
use CGI qw(:standard);
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);

my $cgi = new CGI;

print $cgi->header();
print $cgi->start_html('My test text box');
print $cgi->startform;
open my $FHIN, '<', "./test.file" || die "$!";
my @fhin = <$FHIN>;
print $cgi->textarea(   -name=>'TEXT_AREA',
                        -default=>"@fhin");
print "<textarea> @fhin </textarea>";
print $cgi->end_html();

this produces two empty text boxes. running this from the command line results in:

Content-Type: text/html; charset=ISO-8859-1

<!DOCTYPE html
    PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-U
+S">
<head>
<title>My test text box</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1
+" />
</head>
<body>
<form method="post" action="http://localhost" enctype="application/x-w
+ww-form-urlencoded">
<textarea name="TEXT_AREA" >this is a test file
 this is line two
 three
 4
 foo bar
 six
</textarea><textarea> this is a test file
 this is line two
 three
 4
 foo bar
 six
 </textarea>
</body>

So I know the text is being read into the array. But looking at the source of the page shows no text is being passed:

<!DOCTYPE html
    PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-U
+S">
<head>
<title>My test text box</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1
+" />
</head>
<body>
<form method="post" action="/cgi-bin/cfg_edit.cgi" enctype="applicatio
+n/x-www-form-urlencoded">
<textarea name="TEXT_AREA" ></textarea><textarea> </textarea>
</body>
</html>
[download]

and this is the contents of my test.file:

this is a test file
this is line two
three
4
foo bar
six

This indicates that your cgi script when called from the web server doesn't find or can't read your file. And that's why it is empty. You use `./textfile`. Naturally your webserver has not the same "current directory" as you have. Use an absolute path and one where you know the webserver has access to	[reply] [d/l]
