Hello Monks,

I am trying to perform specific tasks in my CGI script depending on if the "Submit" button is clicked or not.

Basically, I have a dynamic webpage and I am trying to ensure that when the page is first called from browser, some code should be skipped. To do this, I am trying to put a check for Submit button.

I am trying to use $query->param('submit') with a sample code (Test.pl) like:

#!/usr/bin/perl

use strict;
use warnings;
use CGI::Carp qw(fatalsToBrowser);
use CGI qw/:standard/;
use CGI;

my $query = new CGI;
print $query->header;

print <<END_HTML;
        <html><head><title>Thank You</title></head>
        <body>
        <form method="post">
        <input type="submit" value="Submit" id="button1" />
        <br />Thank you - your form was submitted correctly!
        </body></html>
END_HTML

my $a = $query->param('submit');
print "Value: $a\n";

With this code when I access Test.pl from browser, it shows the page with submit button, but even after I click on submit nothing is stored $a.

Can you please help me find what I am missing here? My final goal is to run a chunk of code when the webpage is just fetched but Submit button is not clicked. After submit button is clicked, I am showing the resulting data in the same page.
