## 説明

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](https://github.com/Automattic/Co-Authors-Plus/wiki/Creating-and-editing-guest-authors)
for the writer and assign the byline as you normally would.

On the frontend, use the [Co-Authors Plus template tags](https://github.com/Automattic/Co-Authors-Plus/wiki/Template-tags)
or the [block editor blocks](https://github.com/Automattic/Co-Authors-Plus/wiki/Blocks)
to list co-authors anywhere you’d normally list the author.

### Documentation

 * **Usage** — themer and site-owner guides live on the [GitHub Wiki](https://github.com/Automattic/Co-Authors-Plus/wiki):
   template tags, blocks, guest author management, and multisite.
 * **Developer reference** — lives in-repo under [`docs/`](https://ja.wordpress.org/plugins/co-authors-plus/./docs/?output_format=md)(
   not bundled in the distribution ZIP):
    - [Filters and actions](https://ja.wordpress.org/plugins/co-authors-plus/./docs/filters.md?output_format=md)
    - [REST API](https://ja.wordpress.org/plugins/co-authors-plus/./docs/rest-api.md?output_format=md)
    - [Upgrading to 4.0](https://ja.wordpress.org/plugins/co-authors-plus/./docs/upgrading-to-4.0.md?output_format=md)

Co-Authors Plus is an almost complete rewrite of the [Co-Authors](https://wordpress.org/plugins/co-authors/)
plugin originally developed by Weston Ruter (2007). The original plugin was inspired
by the ‘[Multiple Authors](https://txfx.net/2005/08/16/new-plugin-multiple-authors/)‘
plugin by Mark Jaquith (2005).

## スクリーンショット

 * [[
 * Multiple authors can be added to a Post, Page, or Custom Post Type using an auto-
   complete interface.
 * [[
 * Guest authors allow you to assign bylines without creating WordPress user accounts.
   You can also override existing WordPress account meta by mapping a guest author
   to a WordPress user.

## ブロック

このプラグインは5個のブロックを提供します。

 *   Co-Author Featured Image Uses your theme's image sizes to display a scalable
   avatar for a co-author with a guest author profile. Does not fallback to Gravatar
   images.
 *   Co-Author Avatar Displays a small scale version of a co-author's avatar. Utilizes
   fallbacks from Gravatar so everyone has an avatar.
 *   Co-Author Name Displays a co-author's display name and optionally links to 
   their author archive.
 *   Co-Author Biography Displays a co-author's biographical description.
 *   Co-Authors Displays the co-authors of a post by using blocks to create a template.
   Start with co-author name and add any other co-author blocks.

## インストール

 1. IMPORTANT: If you are using the original Co-Authors plugin, disable it before installing
    Co-Authors Plus.
 2. Extract the co-authors-plus.zip file and upload its contents to the `/wp-content/
    plugins/` directory. Alternately, you can install directly from the Plugin directory
    within your WordPress Install.
 3. 「プラグイン」メニューからプラグインを有効化します。
 4. Place [co-authors template tags](https://github.com/Automattic/Co-Authors-Plus/wiki/Template-tags)
    in your template.
 5. Add co-authors to your posts and pages.

## FAQ

### How do I add Co-Authors Plus support to my theme?

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](https://github.com/Automattic/Co-Authors-Plus/wiki/Template-tags)
before the bylines will appear.

### What happens to posts and pages when I delete a user assigned to a post or page as a co-author?

When a user is deleted from WordPress, they will be removed from all posts for which
they are co-authors. If you reassign their posts to another user, that user will
be the co-author instead.

### Can I use Co-Authors Plus with WordPress multisite?

Yes! You can [use Co-Authors Plus on WordPress multisite](https://github.com/Automattic/Co-Authors-Plus/wiki#wordpress-multisites).
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.

### Who needs permission to do what?

A WordPress user will need the `edit_others_posts` capability to assign co-authors
to posts. This is typically granted to the Editor role but can be altered with the`
coauthors_plus_edit_authors` filter.

A WordPress user will need the `list_users` capability to create new guest author
profiles. This is typically granted to the Administrator role but can be altered
with the `coauthors_guest_author_manage_cap` filter.

### Can I easily create a list of all co-authors?

Yes! You can [create a list of all co-authors with a template tag](https://github.com/Automattic/Co-Authors-Plus/wiki/Template-tags#create-a-list-of-all-co-authors)`
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.

### Can I disable Guest Authors?

Yes! You can disable guest authors entirely through a filter. Having the following
line load on `init` will do the trick:
 add_filter( ‘coauthors_guest_authors_enabled’,‘
__return_false’ )

Would be a 5 star.But since reporting an error for more than a month ago, nothing
has happened.Have to keep previous version to avoid errors.(Not possible for co-
authors to edit posts without error)Would be sorry to find another plugin, since
this seems to be the best.BR Johnny

 [audunmb](https://profiles.wordpress.org/audunmb/) 2024年5月8日

The latest update with new blocks adds much functionality, but unfortunately the
plugin has some bugs and seems to be poorly supported. It’s a volunteer effort mostly,
and there doesn’t seem to be an active maintainer. Currently nearly all support 
questions in the forums are unanswered and lots of issues on GitHub are open as 
well. I wish there was an active maintainer. Still I prefer this plugin over the
alternatives which are a too bloated. With bug-fixes and active support this would
be great.

 [vytecolombia](https://profiles.wordpress.org/vytecolombia/) 2024年1月5日

Simplemente si quieres agregar varios autores a una entrada o simplemente cambiarlos,
este plugin lo soluciona de una manera excelente, intuitiva y sin tanto complique.
Muchas gracias a los desarrolladores, me ha servido bastante. Los quiero mucho.

Plugin also works with Twenty Twenty-Three theme with shortcodes, check “Shortcode
breaks HTML” in the Support section.

 [ivan2343](https://profiles.wordpress.org/bogdan2/) 2023年8月3日 1 reply

After removing this plugin all my posts were broken and I had to recover site from
a backup. Also the newly registered taxonomy here is not public, which leads to 
not being able to view other posts of a particular author. The plugin needs improvement.

### 󠀁[Is it even a plug-in?](https://wordpress.org/support/topic/is-it-even-a-plug-in/)󠁿

 [ncaross](https://profiles.wordpress.org/ncaross/) 2022年11月29日

Plug-ins are supposed to plug-in and work. This one requires you to be a web developer
to make it work. Even if you’re a bit familiar with adding code to places with good
instructions, this just has information for devs on how to install code – there’s
no list of instructions to follow. If this changes because there’s nothing else 
out there, I’ll come back and revise this review, but I’ve wasted way too long on
this now.
