Allows multiple authors to be assigned to a Post or Page via the search-as-you-type inputs. Co-authored posts appear on a co-author’s posts page and feed. New template tags allow listing of co-authors. Editors and Administrators may assign co-authors to a post. Additionally, co-authors may edit the posts they are associated with, and co-authors who are contributors may only edit posts if they have not been published (as is usual).

This plugin is an almost complete rewrite of the Co-Authors plugin originally developed at Shepherd Interactive (2007). The original plugin was inspired by the ‘Multiple Authors’ plugin by Mark Jaquith (2005).

The extended version is created by Mohammad Jangda, and incorporates search-as-you-type functionality for adding users, which aims to make easy the task of adding multiple users to posts and pages, especially when dealing with a system with hundreds of users (typical of newspaper and magazine sites).

Version 2.0 is a major re-write of the plugin to utilize the WordPress taxonomy system instead of post meta.

FAQ

Q. What is the main difference between Co-Authors and Co-Authors Plus?
A. The most notable difference is the replacement of the standard WordPress authors drop-downs with search-as-you-type/auto-suggest/whatever-you-call-them input boxes. As a result, major bits of the JavaScript code was changed to be more jQuery-friendly. Eventually, I hope to include the ability to add new Users from within the Edit Post/Page screen and possibly Gravatar support.

Q. What happens to posts and pages when I delete a user assigned to a post or page as a coauthor?
A. When a user is deleted from WordPress, they will be removed from all posts for which they are co-authors. If you chose to reassign their posts to another user, that user will be set as the coauthor instead.
