Description:

MB Relationships is a WordPress plugin for creating many-to-many relationships between posts, pages, custom post types, terms, and users. You can connect posts to posts, posts to users, and other combinations, then run queries to retrieve items connected to or from a given post, term, or user. The plugin supports reciprocal and bi-directional relationships, and it is lightweight and optimized for database and query performance.

WordPress only offers a built-in way to relate pages through post_parent, which is a one-to-many relationship limited to pages and hierarchical post types. This plugin fills that gap. Typical uses include manually building related posts sections, linking events to bands so visitors can search either direction, connecting products to distributors, or linking singers to songs. It also works with MB Term Meta and MB User Meta to connect posts to terms and users.

The plugin provides simple APIs for registering relationships and retrieving connected items, integrating with existing WordPress APIs such as WP_Query, get_terms and get_users. Relationships are stored in a custom relationship table to optimize database storage and query performance. Each side gets a meta box showing what is connected from and to, so the direction of a connection does not matter. Connected items can be displayed with a shortcode, and documentation is available for more details.

The vendor’s own page for MB Relationships has the full details.
