Ever worked on a WordPress website and wondered how to link posts to each other? Or how to link one of your custom post types to another? After some searching, you’ll find that this isn’t possible with WordPress out of the box.

This isn’t something new. Not being able to create these many-to-many relationships has been a shortcoming of WordPress since day 1. There are some ways to solve this. Misusing Taxonomies is one (not recommend) way. Another way is using one of the few plugins out there that solve this problem. Post Connector and Posts 2 Posts are both examples of plugins solving this issue in their own way. With Post 2 Posts now officially being deprecated, many users are looking for an alternative.
