首先抓取作者的帖子ID，然后抓取术语。

$author_id = \'1234\';
$taxonomy = \'clubs\';

$post_ids = get_posts(\'fields=ids&post_type=post&post_status=publish&showposts=-1&author=\'. $author_id );
$clubs = wp_get_object_terms($post_ids, array($taxonomy));

$html = \'<ul>\';
foreach( $clubs as $club )
{
    $html .= sprintf( 
        \'<li><a href="%1$s">%2$s</a></li>\',
        get_term_link($club, $taxonomy),
        $club->name
    );
}
$html .= \'</ul>\';

echo $html;
