=============

[](#posts-2-posts)

THIS IS A FORK OF THE ORIGINAL PLUGIN. FORKED FOR USE IN GATHER, AS PLUGIN HAS FATAL ERRORS IN PHP8 THAT NEED ADDRESSING AND ORIGINAL IS NO LONGER IN ACTIVE DEVELOPMENT.

Contributors: scribu, ciobi
Tags: connections, custom post types, relationships, many-to-many, users
Requires at least: 3.9
Tested up to: 4.3
Stable tag: 1.6.5
License: GPLv2 or later
License URI:

Efficient many-to-many connections between posts, pages, custom post types, users.

Description
-----------

[](#description)

This plugin allows you to create many-to-many relationships between posts of any type: post, page, custom etc. A few example use cases:

- manually curated lists of related posts
- post series
- products connected to retailers
- etc.

Additionally, you can create many-to-many relationships between posts and users. So, you could also implement:

- favorite posts of users
- multiple authors per post
- etc.

### Support & Maintenance

[](#support--maintenance)

I, scribu, will not be offering support (either free or paid) for this plugin anymore.

Furthermore, I will not be doing any development work whatsoever.

If you want to fix a bug in the plugin or add new features, feel free to fork it [on github](https://github.com/scribu/wp-posts-to-posts). *I will not be accepting any pull requests* though, since ensuring that a code change doesn't break things takes effort, effort which I'm no longer willing to expend.
