wp_unique_post_slug_is_bad_flat_slug WordPress Filter Hook
The wp_unique_post_slug_is_bad_flat_slug hook is used to determine whether a post slug is bad for a flat slug. A flat slug is a slug that is not hierarchical. That is, it can not have / characters in it. A bad flat slug is a flat slug that is not unique. This hook is called when a post is saved and the post slug is found to be bad for a flat slug. The hook is passed two arguments: the post ID and the post slug. If the post slug is not unique, the post ID will be returned. Otherwise, false will be returned. This hook can be used to add custom code to handle the case where a post slug is not unique. For example, you could display an error message or redirect the user to a different page.
