So, actually there is two ways to do it. The first one is using switch_to_blog() and restore_current_blog() functions, example: // in this variable you can pass all the blog IDs you would like to display posts from $blog_ids = array( 1, 3 ); foreach( $blog_ids as $id ) { switch_to_blog( $id ); $args = array(); … Read more
Reading your comment, what you want is to create an author archive using tags and customize the author archive pages. You don’t need tags or categories for that. There is a built-in author archive, by default the URL is in the format yoursite.com/author/username. That URL will show all posts by author and will use the … Read more
My approach would be to: On the Reading Options page, set the For each article in a feed, show… option to Full Text so that, by default, feeds will include the entire post. Pass a custom URL parameter to each individual feed when you want the excerpt instead of the full text. e.g., http://example.com/author/username/feed?format=excerpt. Make … Read more

It operates not much differently than if you installed … Read more

If you wish to use the default widgets in the sidebar and have them filtered by the author only on the author template then I’d suggest using the following approach. First, filter the … Read more
My approach is to create an hourly cron event that loops through all the draft status posts and checks for the publish month – date and hour saved in post_meta and publishes if scheduled date is not in the future. A publish date and time select meta box is added to the publishing div that … Read more
I’ve tested this in WP 4.5 with the default author role and this issue doesn’t seem to exist anymore. My findings: 1 As an author you cannot edit media properties directly. 2 As an author you can edit media properties when you are inserting an image in a post. This will cause the image to … Read more
Found a workaround below. I guess it has to do with a bug in the WordPress core. This will list ALL users in posts, so be cautious. // Filter to fix the Post Author Dropdown function author_override( $output ) { global $post, $user_ID; // return if this isn’t the theme author override dropdown if (!preg_match(‘/post_author_override/’, … Read more
