executing perl cgi script from html

Question

I'm, trying to run a perl script from html, but I'm getting error during execution. Here is my html and 2 lines perl code. The error code is not very descriptive just says "Internal Server Error" and some other lines. I also want to know how to display the receive user name in the perl script.

pwd
/var/www/cgi-bin

ls -l
total 4
-rwxr-xr-x 1 root root 49 Aug 26 16:49 username.pl

Html Code:

<html>
<head>
</head>
<body>
<h1> Hello </h1>
<form action="/cgi-bin/username.pl" method="POST">
     <input type="text" name="username">
     <input type="submit">
</form>
</body>
</html>

Perl code:

#!/usr/bin/perl
print "Received user name is\n";

Your Perl script is not generating appropriate CGI headers. Please read perldoc CGI, or, for a quick answer:

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

my $q = CGI->new();
my $username = $q->param("username");
print $q->header(-type => "text/plain");
print "Received username is $username\n";

1>.my declares the listed variables to be local to the enclosing block, file.

2>.if you have a text box name user in your html page

i.e. something like this:-

<td><b><font color="green" size="3">USER</font><input type="text" name="user" value="">

then try this

my $user=$query->param("user");

in your cgi script and get the input in the variable $user.
