作者变更没有特殊挂钩。

但您可以通过使用post_updated 钩

示例：

add_action(\'post_updated\', \'prefix_on_update_author\', 10, 3);
function prefix_on_update_author($post_ID, $post_after, $post_before)
{

    if ($post_after->post_author != $post_before->post_author) {
        // author has been changed
        // you can add your own hook here or write your code
    }
}
