This script is to be used to redirect users based upon the information
stored in different form elements. When users click on the Submit button,
the script runs, and automatically sends them to the new URL. This is
very useful for people who want to have navigation forms, or simply
Submit buttons where clicking on the button would redirect the user to a
new location.
The script, nph-redr.pl, needs to be placed in your server's cgi-bin and the
anonymous WWW user must have the ability to read/execute the script.
**** IMPORTANT NOTE ****:
The script *MUST* be named 'nph-something' to run.. THE 'nph-' IS
CRUCIAL TO THE SCRIPT, IF IT ISN'T NAMED 'nph-something', IT WILL NOT
RUN!
(Ok, I'm over the caps thing now.. <grin>)
Setting Up the Redirection Script:
==================================
The nph-redr.pl script does not have to be extensively configured to get
it to work. In fact, there is only 1 line you need to modify under the
nph-redr.pl script. You must make sure the top line of the script to matches
the location of you Perl interpreter.
You can find the location of your perl interpreter on your system, by
executing the command: 'which perl' at the Unix command prompt. A typical use
of this command looks like this:
$ which perl
/usr/local/bin/perl
$
In this case, you have just found that the location of Perl on your system to be
"/usr/local/bin/perl". To update the nph-redr.pl script, you need to append
this value to '#!'. So, for this example, the first line the nph-redr.pl
script should look like:
#!/usr/local/bin/perl
Necessary Variables:
--------------------
There Are None! Woo!
However, to configure the script for your WWW Server, you need to complete
the following steps:
1) Type "chmod 755 nph-redir.pl" in the directory where nph-redir.pl resides.
(This makes your script executable)
2) Get a glass of Milk and Cookies.
A Sample Session looks like:
<--- Start Of Captured Session --->
$
$ chmod 755 nph-redir.pl
$
<--- End Of Captured Session --->
Updating The HTML File:
------------------------
Next comes updating the given HTML file. This should be simple, as you
only need to change the settings to your own liking.
First, note the different ways the script can be invoked. With each
method, we are sending one feild of information to the script, and this
feild is named 'dest'. This feild contains the Internet URL that you
want the user to be redirected to.
If you want to redirect users to specific frames, you should add a
hidden field inside your document called 'target'. An example of
redirecting a user to Yahoo, in a frame called "main" would look like
this:
<form action="/nph-redir.pl" method="POST">
<input type="HIDDEN" name="target" value="main">
<input type="HIDDEN" name="dest" value="http://www.yahoo.com">
<input type="SUBMIT" value="Click Here To Visit Yahoo">
</form>
Note how I used a hidden field to point the script to the 'main' frame.
Also note that since there are no variables you need to configure within
the script, you can use an unlimited amount of HTML pages to interface
with it.
