I installed the plugin in production, run the script to popuplate wp_terms, and then added the coauthors to all the posts that required them.

I did notice that when I installed the plugin (maybe after the script ran), all the Posts counts in Users were zeros, instead of the actual number of posts the user had authored. As I updated the coauthors, then the Posts counts were updated to the correct number. This required me to go to at least one post for any author who wasn’t used as a coauthor and click Update to have the Posts count show up in Users.

I will go try the above code now. You could use the register_activation_hook function to call this code when the plugin is activated.

I took a look at wp_terms. Toward the bottom of the table, I see entries for several authors (the ones I did the update post on). They look something like this:

name slug
john.smith cap-john-smith

I assume that the name is the user_login since it can includes uppercase letters, periods, and spaces, unlike the user_nicename.

The slug is cap- plus the user_nicename because the end of the cap- has been normalized to not include uppercase or special characters.

I backed out the code fix referenced at http://pastebin.com/Lb89JP17 that I had previously installed. I then updated (no changes) a post for an author that was showing repeating posts for the same article. When I went to the author page (by clicking on the coauthor_post_links) all was good, no repeating/duplicate posts.

Each time I update a post (making no changes), the author page for that author will now show their posts correctly.

It appears that something is going on when you update a post that fixes the problem. Is there any way to do this in mass?

@daniel Bachhuber – my theme does not have an author.php file.

Read a little bit of the discussion thread. I used mysql to dump the wp_user table, displaying user_login and user_nicename fields. Rarely do they ever match. Many of the user_login values are for example ‘John.Smith’ and the user_nicename becomes ‘john-smith’.

I don’t know if case matters in your comparison, but anytime a user’s user_login has uppercase characters, the user_nicename replaces it with lowercase characters.

Any blank character (space) is allowed in user_login but is replaced with a dash in the user_nicename.

Any period is allowed in the user_login but is replaced with a dash in the user_nicename.

I did not use a plugin that allowed me to modify the user_nicename. They are what the system created.

Is the user_nicename the field that is displayed as Nickname under Edit User?

If the answer is yes, then yes, most user’s Nicknames are changed to be their name followed by a title (like ‘John Smith, Chief Executive Officer, XYZ Company’). and then this is used as the ‘Display name publicly as’ setting.

Are you using this field as a ‘key’ instead of the user_id?

Are you assuming that the Username and Nickname are always equal?
