Why Do You Need Posts To Posts Relationships In WordPress?

Post relationships is a missing part in WordPress. The only «built-in» way that mimic the post relationship in WordPress is the post_parent for pages where you can create many child pages of a page (a one-to-many relationship). Unfortunately, that’s available for pages and hierarchical post types only. Besides, it’s not many-to-many relationship.

Below are some examples of posts to posts relationships that might help you see the benefit of this feature:

Creating Related Posts In WordPress

The simplest example is to manually create related posts in your WordPress website. When you edit a post, you can select posts that have similar or related content and display them in the frontend for further reading.

You can also query backward: displaying posts that link to the being read post as a reference to provide more information to your readers. With this, you don’t need a WordPress related posts plugin anymore.

Example: Events And Bands

Imagina que tienes dos tipos de contenido personalizado, evento y orquesta, donde:

• In each event there may be multiple bands, and
• Each band can participate in many events.

If people want to buy tickets, they could search for events in their location and see what bands are playing on a given date, or they could search for bands they like and see what date they are playing near their location.

En éste ejemplo, hemos creado una relación de varios-a-varios entre eventos y orquestas.

Bi-directional relationships

MB Relationships te permite crear relaciones bidireccionales. Podrás hacer consultas de ida y vuelva sin problemas.

Los datos se almacenan en la base de datos como un par de (from_id, to_id), así los hace independientes en cualquier sentido.

Además, en cada sentido, hay una caja meta que muestra cómo están conectados de/a. No te debes preocupar sobre la dirección de la relación nunca más.

An Alternative For The Posts 2 Posts Plugin (P2P Plugin)

MB Relationships está muy inspirado en el popular plugin Posts 2 Posts que se ha dejado de mantener. Hemos cogido la idea y le hemos realizado unas mejoras. La base del código y las estructura de los datos es muy similar.
