This plugin allow to build relation between 2 custom types (posts, page, custom), very useful for manage related content on CMS type website.
A few example use cases:
<ul>
<li>manually lists of related posts</li>
<li>post series</li>
<li>rented houses connected to agency</li>
<li>etc.</li>
</ul>
Relationships are created from a settings page from the administration console.
This plugin can not do relationships with users, you should test this excellent plugin made by scribu

UM Relational Fields

Does what is says on the box! I needed to link a custom user taxonomy to a custom user profile, followed the instructions and it just worked. Now if Ultimate Member could just make a hierarchical checkbox input field to handle hierarchical taxonomies, it would be even better.



Brilliant

Add relationships between users, post types and taxonomies in your Ultimate Member site.
