Co-Authors Plus is an old and popular WordPress plugin.
By default, WordPress allows you to choose a single author for content. Co-Authors Plus was a solution to this, because it allowed you to assign multiple authors to one content item.
However, Co-Authors Plus has only had a small number of updates in the last few years. Also, it can be hard to use because it requires you to edit your template files.
The Multiple Authors add-on for PublishPress is a fork of Co-Authors Plus that's worth checking out.
We reviewed the main PublishPress plugin, which is a really good editorial calendar. Multiple Authors is an extra feature for that main plugin.
If you install Multiple Authors, you'll see a new box on the right-hand side of all your posts. You can add and remove authors on this screen (click here to learn about Authors permissions in WordPress).
Instead of manually editing your template files, the Multiple Authors add-on gives you several different options to display the authors’ box:
- At the bottom of your content
- In a widget
- Via a shortcode
And yes, if you want to do things manually, there are filters and actions available so you can add the Multiple Authors output to your template files.
However, the widget is probably the easiest and most flexible solution. Here's how the Multiple Authors plugin appears on the frontend of a site:
Multiple Authors Settings
You can access the Multiple Authors configuration screen by clicking on the “PublishPress” link in the WordPress admin menu. After the menu loads, click on the “Multiple Authors” tab:
The "Multiple Authors" feature doesn’t appear on all post types by default. You need to select what post types you want to use:
On this screen, you can easily get the authors to display under the content:
There's also a shortcode available. Just drop [author_box] into your content to get the list of authors.
All-in-all, "Multiple Authors" is a worthy successor to the older Co-Authors Plus plugin and has some nice extra features that make it easier to use.
