Adding extra text relating to the URL

Hi,

Could someone point me in the right direction, as I can't figure this one out.

Essentially I am using a URL of say /news/index.php?division=hotel or more likely /news/index.php/division-hotel

I can use the

<?php echo $_GET['division']; ?> to grab the division for the first option, but that fails for the second option & also fails if the URL is entered just as /news/index.php

However I would like to add extra info on the page depending upon division.

So for example if division=hotel then include external file /news/x.php if division=shop then include /news/y.php if there is no value to division then include /news/z.php

Solving the above would mean only having to create one page.

I have included

<?php echo $_GET['division']; ?>
<?php if ('division' == 'hotel'):?><h2>Hotel</h2>
<?php elseif ('division' == 'shop'): ?><h2>Shop</h2>
<?php else: ?><h2>Other Division</h2>
<?php endif ?>

This works fine as long we do not have /news/index.php without a division mentioned, as we then get an error of Notice: Undefined index: division in /path/to/news/index.php on line 24

It also fails in /news/index.php/division-hotel

Although I have yet to try it, I cannot see why replacing the <h2>Hotel</h2> with the include instruction shouldn't work.

Hopefully you are still with me ;)

I therefore have two questions.....

1) How would I get the code to work with.....
a) /news/index.php and
b) /news/index.php/division-hotel

2) As I would have to replicate this code several times, I might go for individual pages (although I would like to avoid this) - but if I did (useful for reference anyway) how would we display only news items for a particular division and nothing else. So /news/hotel/index.php would display records relating to the division equals hotel etc.

Many thanks.
