OT Drop Down Scripts

Davmagic .Com · Oct 14, 2004

I am currently using JavaScript to run my Drop Downs, and would like to
change to a CGI Script, maybe Perl...

Where can I find a simple and secure Perl script to do this?

cgi-resources.com used to have a bunch of good ones. I haven't been there
lately though.

http://cgi.resourceindex.com/ - if you can't find a ready-written script
to do it you'll certainly find a CGI library that will take care of
getting at the form data.

I looked at cgi resources and couldn't find what I want... no script to
process drop downs... any other suggestions? And since I don't write
script...

What are Drop Dawns?

Well you know the phrase "dawn has broken"? What do you think comes
before the break?

I find that hard to believe ... but I hacked this together in a couple of
minutes. I suggest you learn Perl, it isn't difficult:

(Changes should be obvious. Name your select element "link".)

#!/usr/bin/perl

use strict;
use warnings;
use CGI;

my $site_root = 'http://www.example.com/thing/';

my %pages = (
home => '',
away => 'away/',
far_far_away => 'away/run.html'
);

my $location = $site_root . '/'; # Default

my $cgi = new CGI;

$location = $site_root . $pages{$cgi->param('link')}
if (
defined $cgi->param('link') &&
defined $pages{$cgi->param('link')}
);

print <<EOF;
Location: $location
Content-Type: text/html; charset=iso-8859-1

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

<title>Document Found!</title>
<h1>Document Found!</h1>
<p>The document you were looking for can be found at
<a href="$location">$location</a>.</p>

Learn to write script. It's easier with PHP, so perhaps starting at
http://www.php.net/ would be good.

I don't. English ain't my mother tonge
What are Drop Dawns in this context?

In this context ... you are still misspelling them. See the subject for the
correct spelling.

A "Drop Down" is, I suspect, referring to a <select> element since they are
commonly rendered as what, in most GUI toolkits, are referred to as Drop
Down Menus.

What do you mean, "run your drop downs"?

The OP seems to loose interest, but to me too the question as is makes no
sense

What do you mean, "run your drop
downs"?

JavaScript processes the drop down select element.... causing the
browser to goto the chosen option value.... source my front page to see
the code for the drop down on it... as an example

I want to use a Perl CGI Script to eliminate the 11% (or so) who have JS
disabled on their browsers...

...but can't seem to find a readily available script, that will work
just like the JS that I use now... ie goes to the page when the select
option is clicked, without having a "Go" button to press... and goes
_directly_ to the page, without having the script return a page with a
link on it, to be clicked to goto the desired page (as David Dorward's
script proposal suggests)...

If I were you, I'd use a combination Javascript and PHP solution. This
will use Javascript for those who can, and fall back to PHP for the rest:

In your <head>:

<script type="text/javascript">
function redirect() {
var sel = document.getElementById("r");
var sid = sel.selectedIndex;
var page = sel.options[sid].value;
window.location.href = page;
return false;
}
</script>

In your <body>:

<form action="/redirect.php" method="GET" onsubmit="redirect();">
<div>
<select id="r" name="r">
<option value="/index.html">Home</option>
<option value="/contact.html">Contact Me</option>
<option value="/blah.html">Blah</option>
</select>
</div>
</form>

And here is redirect.php, which should be put into your document root:

<?php
$page = $_GET['r']
header('HTTP/1.1 302 Found');
header("Location: $page");
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<title>HTTP/1.1 302 Found</title>
<h1>HTTP/1.1 302 Found</h1>
<p>The document you were looking for can be found at
<a href="<?= $page ?>"><?= $page ?></a>.</p>

and that's it. More efficient that a straight server-side redirect.

Argh! You're going to want a submit button in there somewhere too!

<snip code>

Thanks, but it doesn't seem to work... I copied all your code,
implimented it as you indicated, but get an ERROR "File not found" when
hitting the submit button!

Again I don't need a submit button with the current JS script that I now
use... and would like to "keep it that way" with any other scripts that
I convert to...

But your code doesn't seem to work as you explained anyway, I had JS
enabled, but it used the form action and used the php script anyway...
did not use the JS? Still did get the ERROR...

Let's have a look. URL?

Well, you can't. Tough. Without a submit button, how can people submit the
form?

The JS that I am using now, uses the "onchange" event for the select tag
to submit the form, here's the URL: http://davmagic.com/index.html

Why can't this be done with another non-JS script?

There are two ways to submit forms. With client side scripting (which isn't
reliable) and with submit buttons (which have to be activated by the user).

First thing to check: does your server support PHP?

Not possible. The form must be submitted to the serve in order for a
server side script to handle it. This requires either JavaScript
(pointless if the server side script is a fallback for when JS is
disabled) or a submit button.
