This will work for validating a html uri for the w3c validator.
If you change parts of it around for your site you can get it to work for the css validator too.

*(also--dont shun me if someone else did this before me, I am pretty sure that if they did it isnt very well publicized because I didn't find it the first 5 minutes of searching. Either way, here is the story):

I was tired of making validation links and sick of seeing headers not going through firewalls, among other issues. So to make it easy for me I put this little thing together:

hope it helps:

<a href="http://validator.w3.org/check?uri=<?php

$main = $_SERVER["SERVER_NAME"];
$path = $_SERVER["REQUEST_URI"];
echo "http://" . $main . $path;

?>">
<img src=" [image location here] " alt="Valid XHTML 1.1"/>
</a>
