MB Relationships

Descripción

MB Relationships helps you create relationships between posts, pages, custom post type, terms and users. The plugin is lightweight and optimized for database and query performance.

The plugin allows you to create connections from posts to posts, posts to pages and so on. Then you can perform corresponding queries to retrieve posts that are connected to or from given posts.

It supports reciprocal and bi-directional relationships.

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.

Plugin features

  • Simple APIs: the plugin provides simple APIs for registering relationships and retrieving connected items. It integrates with existing WordPress APIs such as WP_Query,get_terms and get_users. See documentation for more information.

  • Supports creating bi-directional relationships and easily query them.
  • Display connected items easily with shortcode.

The plugin itself seems powerful. However I wouldn’t know because it’s very difficult to use unless you’re a developer. Be aware that there is no UI with this plugin, it adds a capability to your site but you have to handle code to use it. The documentation is written for developers. Even if you’re willing to learn, the doc provides little examples; mostly short snippets that you must know where and how to use. To top it all, the support team answers novice questions mainly by redirecting to the documentation, and make it clear that they’re not willing to help you below a certain developing skill level. So unless 1) you’re a developer, 2) you are willing to hire one to use this plugin, or 3) you use a page builder that integrates with Metabox and MB Relationships specifically (Oxygen for example), I suggest you pass. Nothing wrong with making plugins for developers only, it’s a design and business decision by Metabox. But the plugin presentation makes it seem fairly beginner-friendly. It is not, you should be aware of it.

Sadly, there is no support for this plugin. I posted a bug report here: https://wordpress.org/support/topic/sort-order-in-the-metabox-lost-or-reversed/ and here: https://github.com/wpmetabox/mb-relationships/issues/13 more than two weeks ago, but nobody bothers to reply… Edit 1: +2 stars for replying to the bug report. Edit 2: +2 stars for fixing the bug and now working really well.
