How to specify multiple authors?

[timotk]

• Multiple authors is possible in Wordpress
• When downloading an existing post with multiple authors to markdown, there is only one author in the markdown frontmatter.
• How can we specify multiple authors in markdown?

Multiple authors is not yet supported. I will fix that when I get back for holiday

I was looking into adding this as I wanted to add a multi-author blog to the xebia-blog repo.
For multiple authors you need to get the id for multiple users, see this code. I'm not allowed to because listing users is only allowed as Administrator.
I tried to work around it by manually providing the user id. However, wordpress does not support multiple authors by default. We are using the Co-Authors-Plus plugin to enable multi-author. This means we cannot create/update a blog post with multiple authors via the Wordpress REST API.
AFAIK, the plugin also doesn't support creating/updating a post with multiple authors either.

@Roymprog yes I reached that conclusion as well. Wordpress is an insanely popular and inept system..

You would need to make PR on the Co-Authors-Plus plugin to support multiple authors.

To complicate matters, the coauthor user id is not the user id of the user in WP.
