Exercise: Strings, HTML, Perl

• Write an HTML page with a form.  The form should have two text entry fields: one for the first name, and one for the last.  It should also have a submit button.
• The ACTION of the form tag should point to the Perl script you write below.  The URL will be: http://homepages.uc.edu/cgi-bin/cgiwrap/username/perlscriptname.pl where username is your user name (bearcat ID), and perlscriptname.pl is your perl script name.  No tilde for the user name.
• METHOD can be POST or GET, but I usually use POST.
• Now, write a Perl script.  The script should:
• Start with the shebang line:

#!/usr/local/bin/perl
• Use the CGI.pm library, and create a new CGI object:


#    Use the CGI.pm library
use CGI;

# Make a new CGI object.
$query = new CGI;

• Next, use the CGI.pm methods to write the start of the form:

#   Write out the content-type header followed by a blank line.
print $query->header;

#   Write the HEAD section, including the title.
print $query->start_html("String Concatenation");
 

• Then, retrieve the first name and last name.

$firstName = $query->param('firstName');
$lastName = $query->param('lastName');
 
• After that, print a welcome message, using the first and last names.  You can:
• concatenate them into one string ahead of time using the . operator, or
• use double quotes to have Perl interpret the scalars on the fly, or
• use both methods.
Whatever you do, I leave this implementation up to you.  See me if you have questions.
• Finally, end the form.

#   End the form.
print $query->end_html;
 
• Also, you may need to set permissions for the Perl script.  Logon to oz and type this:

cd .www/cgi-bin
chmod 755 the name of your Perl script
• If you create the HTML file with pico, you will need to do this:

cd .www (from the home directory, or cd .. from cgi-bin)
chmod 744 the name of your HTML file
•  See an example, and get the source HTML (To get the source, go to View-Source on your browser, and you can copy and paste it into your favorite text editor.)
