SLIDE #7 A CGI PROGRAM PROCESSING A SELECT FORM


In this seventh slide, we introduce the CGI program processing the select form.

The CGI/Perl program gets the value selected, using:
$val=$query->param('link');
then we use the redirect method to display the new page:
$redir= $query->redirect($val);
we finally use the print statement to activate the redirection
print $redir;

1. THE CGI PROGRAM:

#!/usr/local/bin/perl
use CGI;
$query=new CGI;
$val=$query->param('link');
$redir= $query->redirect($val);
print $redir;

2. PROGRAM DESCRIPTION:

The first three lines are identical as slide #4

The fourth line gets the selected value

The fifth line calls the redirect method

The sixth line sends the result back to your browser.
