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.
Meta Box Lite
We recommend using Meta Box Lite, a feature-rich free UI version of Meta Box that provides UI and all free features for managing custom fields and dynamic content on WordPress, including post types, taxonomies, custom fields, and relationships.
It supports reciprocal and bi-directional relationships.
Post relationships is a missing part in Word…
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.
