How to list all articles from an author Wordpress-CodePudding

I try to find all the articles associated to an author, even those reallocated to another author in the meantime. Have you any ideas about that ? Thank you in advance !

CodePudding user response：

Yes, it's simple. First get all the users with author role and then pass those user_ids to WP_Query().

To get user_ids:

function author_ids_by_role() {
    $user_ids = get_users(array('role' => 'author' ,'fields' => 'ID'));
    return $user_ids;
}

Now, in WP_Query():

$user_ids = author_ids_by_role();
$args = array(
    "posts_per_page"  => 10,
    "post_type"       => "post",
    "author__in"      => $user_ids
);
$wp_query = new WP_Query( $args );
