[wp-hackers] post id in custom template

[Mark Jaquith]

For getting the post ID in a the_content filter, I've just either 
declared $id global and used that, or declared $post global and used 
$post->ID  Using $post is better if you need other stuff as well, 
because you can just "globalize" the $post object and be done with it.
