Just to quickly answer this other question. Some filters and actions
pass multiple values so that you can also have information like
page/post id. In this case its not available though.
Luckily one thing that tends to work for situations like this is to
globalize $post. If you're in the loop or on a single article page
(whether in the admin or frontend) $post normally contains the full
object for the post being worked on.
So in your filter function you can probably do:
Note that $post is used even if its a page.
