Hello,
I am looking for a query I can use within a Looper Provider to grab the siblings of the current page (i.e. the children of the current page’s parent). Ideally, the query would exclude the current page as well.
I am trying to avoid using the parent’s page ID so that I can use it in a layout…
So far, post_type=page&post_parent=13 works but post_type=page&post_parent={{dc:post:id} doesn’t.
Secondly, for the parent page:
what conditions could I give a layout so that it applies to all parent pages (but not pages that have no children)?
