%ENV is returning a blank

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

I have a simple online form, however when I fill it in using "get" it returns an empty QUERY_STRING. When I use the "post" method, it gives me CONTENT_LENGTH=0. I cannot figure out what I am doing wrong.

Here is the xml code

<?xml version="1.0" encoding="utf-8" ?>

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>Make a booking</title>
        <script src="makeBooking.js" type="text/javascript"></script>
        <link rel="stylesheet" type="text/css" href="makeBooking.css" 
+/>
    </head>
    <body>
        <form id="frmBook" action="/cgi-bin/makeBooking.pl" method="PO
+ST">
            <table id="tblBook" >
                <tbody id="tblBookBody">
                <tr id="nameRow">
                    <td class="left">Name</td>
                    <td class="right">
                        <input id="txtName" type="text" />
                    </td>
                </tr>
                <tr id="dateRow">
                    <td class="left">Date</td>
                    <td class="right">
                        <input id="txtDate" type="text" />
                    </td>
                </tr>
                <tr id="durationRow">
                    <td>Duration</td>
                    <td class="right">
                        <input id="txtDuration" type="text" />
                    </td>
                </tr>
                <tr id="venueRow">
                    <td>Venue</td>
                    <td class="right">
                        <input id="txtVenue" type="text" />
                    </td>
                </tr>
                <tr id="otherInfoRow">
                    <td>Other Information</td>
                    <td class="right">
                        <textarea id="otherInfoTxt" rows="5"></textare
+a>
                    </td>
                </tr>
                <tr>
                    <td class="left">
                        <div><input type="submit" value="Submit" /></d
+iv>
                    </td>
                    <td class="right">
                    <div>
                        <input type="reset" value="Reset" />
                    </div></td>
                </tr>
                </tbody>
            </table>
        </form>
    </body>
</html>

and here is the perl script:

#!/usr/bin/perl

print "Content-type: text/html\n\n";


print "Query string=$ENV{'QUERY_STRING'}";
[download]

Simple code, I know, but I can proceed to better things once that simple test works

The output I get is

Query string=

I am not sure where the problem lies, however, I am confident the wise monks know and I look forward to your assistance.

Your form is sending POST data and you're trying to decode GET data... they're not the same thing. I highly suggest you spend some time learning CGI and I also recommend using the fine CGI module to help you do it right.	[reply]

Sorry, I posted the above in a hurry before I went to work, I therefore got the post and get methods mixed. I have tried both, post and get, and both give me empty data back.	[reply]

Instead of your program, try something like this instead `#!/usr/bin/perl -- use strict; use warnings; use CGI; use Data::Dumper; #zum debuggen Main( @ARGV ); exit( 0 ); sub Main { my $cgi = CGI->new; print $cgi->header(); # Write HTTP header print $cgi->start_html, $cgi->b(rand time, ' ', scalar gmtime), '<table border="1" width="%100"><tr><td>', $cgi->Dump, '</td><td><div style="white-space: pre-wrap; overflow: scroll;">', $cgi->escapeHTML( Dumper( $cgi ) ), '</div></td></tr></table>', CGI->new( \%ENV )->Dump, $cgi->end_html; }` [download] Reading the manual is fundamental	[reply] [d/l]

I am not sure where the problem lies... Find out how QUERY_STRING works and you'll have your answer	[reply]
