I recently had a need to rewrite the URLs of all parent and child pages in a custom post type so that they appeared to live at the website root, but in reality, continued to live in a custom post type within their hierarchy.

Preface

The situation:

1. I have a page called Services that lives at domain.com/services.
2. I have a custom post type called Services.
3. I have Services post called Programming that lives at domain.com/services/programming.
4. I have Services post called Web Development, that is a child of Programming, that lives at domain.com/services/programming/web-development.

The goal:

1. The Services page should remain where it is i.e. domain.com/services.
2. The Programming post should appear to live at the website root i.e. domain.com/programming.
3. The Web Development service should also live at the website root i.e. domain.com/web-development.

The reason:

1. Shorter URLs.
2. Keep all website pages together.
3. Keep all services together.
4. Maintain hierarchy of services.
