توضیحات
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
Suppose you have two custom post types, event and band, where:
- 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.
In this example, we have created many-to-many relationships between events and bands.
Bi-directional relationships
MB Relationships allows you to create bi-directional connections. You will be able to query back and forth without any problem.
The data is stored in the database as a pair of (from_id, to_id), thus making it independent from either side.
Besides, for each side, there’s a meta box that shows what are connected from/to. So you don’t have to worry about the direction of the connection anymore.
An Alternative For The Posts 2 Posts Plugin (P2P Plugin)
MB Relationships is very much inspired by the popular plugin Posts 2 Posts which is not maintained anymore. We have taken the idea and made some improvements. The codebase and data structure is very 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
andget_users
. See documentation for more information. - Uses custom relationship table to store relationships. That helps optimize the database storage and query performance.
- You can create relationships between any kind of content in WordPress: posts to posts, posts to users, etc. For posts to terms and posts to users, it’s required the MB Term Meta and MB User Meta.
- Supports creating reciprocal relationships (posts-posts, users-users, …).
- Supports creating bi-directional relationships and easily query them.
- Display connected items easily with shortcode.
- Extremely lightweight and fast.
