Adding a token to a views block title I am displaying some view blocks on a page. The content is being filtered by passing the nid from the url into some custom php. I wish to change the block title to use a field from the node in question. Is this possible?
For Views 3 , the given answers are partially incorrect. Tokens are allowed in the header area of view blocks. The only tokens available are for the fields used in the view. So you can set the field that will be used only for its token to hide.

You have to select the Global: Text area option in Header, check Use replacement tokens from the first row and select the token from the Replacement Patterns dropdown.
