CoAuthors Plus: Add multiple authors to posts via WordPress plugin
Do you have a blog or website such as a news website where multiple authors collaborate to write a story or an article? Do you publish guest articles without creating new authors as a user in your WordPress site?
Co-Authors Plus is a plug-in that allows you to have multiple authors or a guest author for an article. You can assign multiple bylines to posts, pages, and custom post types via a search-as-you-type input box. Co-authored posts appear on a co-author’s archive page and in their feed. 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 core behavior).
Add writers as bylines without creating WordPress user accounts. Simply create a guest author profile for the writer and assign the byline as you normally would.
On the frontend, use the Co-Authors Plus template tags to list co-authors anywhere you’d normally list the author.
