The first author of a post has the ability to delete it (depending on status, etc), but co-authors can't. Wordpress checks the capability "delete_others_posts" for co-authors, even though they're an "author". Basically, to the co-author, the option to "Move to Trash" is not displayed.
A functional workaround: the co-author can rearrange the authors to make themselves the first author, save, then delete the post.
I added the following fix for our environment. It may not work properly with other environments/workflows.
function allow_coauthor_delete($allcaps, $cap, $args) {
if ($cap[0] === 'delete_others_posts') {
if ($allcaps['delete_others_posts'] == true) {
return $allcaps;
}
if (current_user_can('edit_post', $args[2])) {
$allcaps['delete_others_posts'] = true;
}
return $allcaps;
}
return $allcaps;
}
add_filter('user_has_cap', 'allow_coauthor_delete', 10, 3);
