I know to get widgets to show up on specific pages I put:
!is_page( array( ID#, ID#, ID# ) )
But how do I instead exclude pages? For example, I want some ads only on 3 out of 100 pages, so I don't want to put 100 ID's in there. Is there a way to do this? I thought it would be by using
!is_single( array( ID#, ID#, ID# ) )
But that is not working. Any suggestions, or is this not possible?
