That does work! Thanks.
I have to repeat this several times in the template for each connection, count the number and if the total is greater than 0, draw a styling block to contain the connection details.
So, I tried to create a function in my core functionality plugin, like this:
function swg_count_connections_single($post_id,$connection_type){
$connected = new WP_Query( array(
'connected_type' => $connection_type,
'connected_items' => $post->ID,
) );
wp_reset_postdata(); // is this needed?
return $connected->found_posts;
}
and called it in the template (for testing purposes) like this:
$swg_count_of_connections = swg_count_connections_single($post->ID,'builders_to_toys');
echo $swg_count_of_connections;
This doesn’t work, it always returns zero. What am I missing?
