Accessing URL parameters from a snippet

I am trying to develop a web app using MODx Evolution and am new to writing snippets. I would like to have a single MODx page as the target for accessing the data in the database. To do this, I thought it would be best to make a URL that looks like [tt]http://www.mysite.com/page/param[/tt] or [tt]http://www.mysite.com/page?q=param[/tt] and use the param to feed my snippet so it knows how to query the database. Is there a way to access the URL inside the snippet so I can grab the param? Should I consider a different approach?

I don’t want to litter the MODx doc tree with thousands of documents and assign aliases to each when a simpler and cleaner method can be used.

Thanks for your help.

Of course! For some reason, I was thinking that there must be some special MODx way to do it.

Thanks!

<?php
$val = $_GET['type'];
$output = '';
// your db snippet query code here
return $output;
?>

Improve, that you validate each get parameter, you’ll work with.
remember: all input from userland is evil so avoid all the XSS-injuries. like this: http://ha.ckers.org/xss.html
