Description
This is very similar to #22902, but affects hierarchical post types. See #meta523.
Steps to reproduce:
- Create a hierarchical CPT, e.g. "handbook".
- Add a top-level post called "Getting Started".
- Add another top-level post called "Contributing to the WordPress Codex".
- Add a third post called "Getting Started" and select the previous post as a parent.
- You should get this structure as a result:
/handbook/getting-started/ /handbook/contributing-to-the-wordpress-codex/ /handbook/contributing-to-the-wordpress-codex/getting-started/
- Now go to
/handbook/getting-started/. Instead of just a top-level "Getting Started" post, you'll see two posts with the same title displayed insingle.phptemplate.
Has been this way since [13774].
WP_Query has an assumption that a top-level post of a hierarchical CPT can use name query var. However, we don't check for duplicate slugs in this case. Looks like hierarchical post types should always use pagename.
