您可以筛选get_blogs_of_user 并将此特定博客添加到返回的列表中。伪代码，未测试：

add_filter( \'get_blogs_of_user\', \'add_special_blog\', 10, 3 );

function add_special_blog( $blogs, $user_id, $all )
{
    $new_blog = get_blog_details( $special_blog_id );

    $blogs[ $special_blog_id ] = (object) array(
    \'userblog_id\' => $special_blog_id,
    \'blogname\'    => $new_blog->blogname,
    \'domain\'      => $new_blog->domain,
    \'path\'        => $new_blog->path,
    \'site_id\'     => $new_blog->site_id,
    \'siteurl\'     => $new_blog->siteurl,
    \'archived\'    => 0,
    \'spam\'        => 0,
    \'deleted\'     => 0
    );

    return $blogs;
