TL;DR

AI summary of the plugin's readme

This plugin is for WordPress site owners and publishers who need to credit multiple writers on a single piece of content. It solves the problem of the default WordPress single-author model by allowing multiple bylines, including guest authors without user accounts, to be assigned to posts, pages, and custom post types.

Frequently Asked Questions

Common questions about Co-Authors Plus

If you've just installed Co-Authors Plus, you might notice that the bylines are being added in the backend but aren't appearing on the front end. You'll need to add the template tags to your theme before the bylines will appear.

Yes! You can use Co-Authors Plus on WordPress multisite. Co-Authors Plus can be activated on a site-by-site basis or network-activated. If you create guest authors, however, those guest authors will exist on a site-by-site basis.

By default, a WordPress user needs the edit_others_posts capability to assign co-authors to posts, or the equivalent for other post types, such as edit_others_pages for pages. This is typically granted to the Editor role but can be altered with the coauthors_plus_edit_authors filter. The roles and capabilities guide has an example that lets the Author role assign co-authors. A WordPress user will need the list_users capability to open the Guest Authors screen. This is typically granted to the Administrator role but can be altered with the coauthors_guest_author_manage_cap filter. The roles and capabilities guide covers every permission check in detail.

Yes! You can create a list of all co-authors with a template tag coauthors_wp_list_authors() template tag. This template tag accepts many of the same arguments as wp_list_authors(). Look in template-tags.php for more details.

Yes! You can disable guest authors entirely through a filter. Having the following line load before init (for example in your theme's functions.php or in a plugin) will do the trick: add_filter( 'coauthors_guest_authors_enabled', '__return_false' )

Yes. Many parts of Co-Authors Plus can be changed with a filter, for example making every byline come from guest authors, or stopping author archives from matching on the post's WordPress author. See Customizing Co-Authors Plus for recipes, and the filters and actions reference for the full list.
