Problem: I have a post relationship between two post types. I want to show a View of child posts where the parent post is not private.
Solution: Use custom code to test each child post's parent. Private parent posts will not be returned for any guest Users. Also test the post status, so logged-in Users will not see child posts of their own private parent posts.
add_filter('wpv_filter_query', 'ts_parent_not_private_func', 10, 3);
function ts_parent_not_private_func($query, $view_settings, $view_id) {
$views = array( 16813, 16403 ); // only filter these views
if( in_array( $view_id, $views ) ) {
$child_ids = array(); // we will push IDs here if the parent is not found, or private
$children_args = array(
'post_type' => 'training-datum',
'posts_per_page' => '-1',
'post_status' => 'publish',
// you may want to add more filters here to improve the performance of this query
);
$children = new WP_Query($children_args);
foreach( $children->posts as $child ){
$parent = toolset_get_related_post( $child, 'training_training-datum', 'parent' );
// if there is no parent or the parent is private, push this ID into the exclusion array
if( !$parent || get_post_status($parent) == 'private' ){
array_push( $child_ids, $child->ID );
}
}
$query['post__not_in'] = isset( $query['post__not_in'] ) ? $query['post__not_in'] : array();
$query['post__not_in'] = array_merge($query['post__not_in'], $child_ids );
}
return $query;
}
