WP_Query with two post types, but requiring category on only one of those post types
I have a simple WP_Query:
$loop = new WP_Query(array( 'post_type' => array('image', 'video'), 'category_name' => $cat, 'meta_key'=>'total_votes', 'orderby'=>'date meta_value_num' ));
How can I alter this so that it return only videos with the tag
editor-pick while still returning all images regardless of tags?
I’m looking for a filter to add onto the MySQL query so that order and pagination remain intact.
