Also, it would really help to be able to do this check in queries, e.g. to exclude co-authored posts from author template pages.
Anyone?
This is pretty important, since not excluding the co-authored posts from author archive pages may result in a lot of duplication (same post shows in main archive, and in all co-authors’ author archives; if you have three co-authors for an article, that’s four places where that article shows up).
I have managed to use a pre_get_posts filter used exclusively on the author archive pages, using a taxonomy query like this:
`$tax_query = array(
array(
‘taxonomy’ => ‘author’,
‘field’ => ‘name’,
‘terms’ => $query->query_vars[‘author_name’] ,
‘operator’ => ‘NOT IN’
)
);`
This trick basically makes sure the current author is not among the co-authors of their own articles, which should be true for all articles that are not co-authored, if the ‘author’ taxonomy is not set AT ALL for those articles.
Trouble is, the plugin seems to set the ‘author’ taxonomy for all new single-author articles anyway, even if they are not co-authored. This renders the above solution useless.
Any other ideas?
