Shortening urls.. with multiple extensions

[Maggan]

Hi, I've long had this php include on my site

<?php
$page="home.html";
$content=$GET['x'];

if ($GET['x'] == "") $content = $page;
else $content=$_GET['x'];

include($content);
?>

But, I want to be able to shorten the urls so that I'll have links looking like this index.php?x=home&nav=nav as opposed to the old index.php?x=home.html&nav=nav.php And that right there is my problem... I have includes of several file extensions... .gif,.php,.html,.jpg

So now I need to find that missing line in the following script, which defines what possibilities there are for extensions... I've labeled it $ext as you can see.

<?php
$page="home";
$content=$GET['x'];

if ($GET['x'] == "") $content = $page;
else $content=$_GET['x'];

include("$content.$ext");

?>

Anyone want to help?

Unfortunately, your initial way of including is a major security threat. Read this thread for some ways around it (utilizing &page=home like you want is one of them).

Well then... ::freaked:: Now I'm even more anxious to get help then. So how do I select which file extensions are allowed for inclusion?
