I have a similar is issue when trying to do this:
function my_post_object_query( $args, $field, $post )
{
// filter by the posts current categories
$args['cat'] = implode(",", wp_get_post_categories($post->ID));
echo "<pre>";
print_r($args);
echo "<pre>";
return $args;
}
add_filter('acf/fields/post_object/query/key=field_524f02159316d', 'my_post_object_query', 10, 3);
The category filter is not picked up… same as above, the post_object.php is using get_pages() against a custom post type.
Suggestions other then changing the core file?
