I must be a bit slow, I still have problems with the position field in the Posts-2-Posts plugin. If I set a position to each connection in a given post (say 1, 2 and 3) I don't understand how to display these connections in this order. I thought this would do the job :
$xxx = new WP_Query( array( 'post_type' => 'author', 'p2p_orderby' => 'position', 'connected_order' => 'desc', 'connected_from' => get_the_ID() ) );
It doesn't. The position field is just not taken into account at all, even if I remove the line « 'p2p_orderby' => 'position' ». What do I do wrong ?
