I'm trying to use query_posts to fetch posts, excluding those with custom field values that are in a provided array.
Here is the meta_query part of query_posts that I am using:
array( array( 'key' => 'special', 'value' => array( 'val1', 'val2', 'val3' ), 'compare' => 'NOT IN' ) )
To clarify, I want to fetch all posts, except those that have val1, val2 and/or val3 as 'special' meta values. In theory this meta_query code work, but it is still fetching posts that have the specified meta values.
Would really appreciate any insight into why this isn't working!
Thanks!!
