Re: Taking Variable from Form Entry Using CGI

Are you not using CGI because you want to know how's the guts of all that stuff?

Then you should dump all your environment variables and what you read from STDIN into some file and examine it.

As for POST, I doubt that this works:

# Split the name-value pairs
@pairs = split(/&/, $query_string);

Otherwise, just use CGI and have that module give you the content of the textarea:

#!/usr/local/bin/perl
use CGI;
use strict;

my $q = CGI->new;

print $q->header;

my $text = $q->param('comments');
my $words = scalar(split (/ /, $text));

#Give output
print <<END;
<html><head>
<title>Guest book Result</title>
<body>
<h1 align="center">Guest book Results</h1>

<br>
Comments : $text
<br>
Words: $words

</body>
</html>
END
[download]

Cleaner code, less hassle.

Thanks for the reply. Unfortunately, I get the following error: `Can't locate HTML/TokeParser/Simple.pm in @INC (@INC contains: C:/Prog +ram Files/xampp/perl/site/lib/ C:/Program Files/xampp/perl/lib C:/Pro +gram Files/xampp/perl/site/lib .

The CGI.pm included with the perl core doesn't use HTML::TokeParser::Simple (at my unix box, that is - dunno of windows). It must be pulled in somewhere else. Use the search facility of the windows explorer to identify that file. If you just happen to use CGI, check the location of CGI like so `print STDERR $INC{'CGI'}."\n";` [download] anywhere in your cgi file, and check the apache error_log. Many modules have a Package::whatever::CGI, but you should be using the core CGI.pm, not Package/whatever/CGI.pm. HTH, --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.

At the command prompt type the following: `perl -MCGI -e "print $CGI::VERSION;"` [download] ...and then tell us what output you get. Do you still get that HTML::TokeParser error? If not, then the error has nothing to do with your use of CGI. If you do, I'm perplexed. ;) Dave	[reply] [d/l]
