In particular we can make use of the meta_query attribute (see Codex): $meta_query = array( array( ‘key’=>’featured’, ‘value’=>’yes’, ‘compare’=>’!=’, ), ); … Read more
I have been searching for hours for a solution to this problem. Array merging is not the way to go, especially when the queries are complex and you must be able to add to meta queries in the future.
