Create a html file and perl script using following steps.


Step 1: Creating a web page add.html

Open your console and type:

$ sudo gedit /var/www/add.html

Copy the lines below in the file and save it.

<html>
<head>
<title>Addition of two numbers.</title>
</head>
<body>
<br><br><br><br><br>
<form action=’cgi-bin/add.pl’ method=’post’ enctype=’multipart/form_data’>
<table border=’0′ align=’center’>
<tr><td colspan=’2′ align=’center’>
<b>Adding Two Numbers</b>
</td></tr>
<tr>
<td>Enter the first value:</td>
<td><INPUT TYPE =’text’ NAME=’n1′></td>
</tr>
<tr>
<td>Enter the second value:</td>
<td><INPUT TYPE =’text’ NAME=’n2′></td>
</tr>
<tr><td colspan=’2′ align=’center’>
<INPUT TYPE =’submit’ VALUE=’ADD’ NAME=’submit’>
</td></tr>
</table>
</form>
</body>
</html>


Step 2: Creating a perl script add.pl

Open your console and type:

$ sudo gedit /usr/lib/cgi-bin/add.pl
$ sudo chmod a+x /usr/lib/cgi-bin/add.pl

The command chmod a+x is used to allow permission to run the script. Without using this command your program will not run. !!!

Copy the lines below in the file and save it.

#!/usr/bin/perl -w
use CGI;
CGI::ReadParse();
$numb1 = $in{’n1′};
chomp($numb1);
$numb2 = $in{’n2′};
chomp($numb2);
$numb3=$numb1+$numb2;
CGI::PrintHeader();
print “content-type:text/html\n\n”;
print “<HTML>\n”;
print “<head><title>Addition of two numbers</title></head>\n”;
print “<body>\n”;
print “<br><br><br><br><br><center>Addition of $numb1 and $numb2 is $numb3.</center>\n”;
print “</body>\n”;
print “</html>\n”;


Step 3: Running the program

Open web browser and hit address http://localhost/add.html to run the Perl/CGI program.
