I'm using WP_Query to select a specific set of posts:
$args = array ( 'orderby'=>'rand', 'posts_per_page' => 1, 'category_name'=>'exercise', 'tag' => 'org:abc' ); $the_query = new WP_Query( $args );
but, when I run the query, it seems to be stripping the colon (:) in the tag name, so the query (when you output it) is searching for tag='orgabc', rather than 'org:abc'.
This also seems to happen with =, i.e. 'org=abc'
I've had to change my taxonomy as a result, but does anyone know why the colon is being stripped? is this a special character?
