Is there a way to validate a whole site at once? I'm using the w3's HTML validator and haven't seen a way to do it other than page by page. Also, for some reason, I'm not able to validate my local files which means I have to reupload every time I make changes.

Also, the site is in PHP and I'm using quite a lot of templates. Some popup pages are dynamically generated using $_GET or $_POST variables. I'm not sure how to validate those aside from copy/pasting the top and bottom template portions to the body portions of each of the popup window content files and validating that new page one at a time.

Any tips?
