例如，如果你想得到一个演员的职位，有不同的解决方案，但在我看来，最好是使用tag 作为演员的名字，或post meta. 目前我给你的解决方案是使用WordPress搜索系统并尝试查找帖子。

// We try to get post for Christian bale as a keyword
$args = array(
    \'post_type\'     => \'post\',
    \'post__not_in\'  => array(get_the_ID()), // We don\'t need the current post
    \'s\'             => \'christian bale\', // We put the Christian Bale search here
);

// Or as a meta value
$args = array(
    \'post_type\'     => \'post\',
    \'post__not_in\'  => array(get_the_ID()), // We don\'t need the current post
    \'meta_key\'   => \'director\',
    \'meta_value\' => \'christian bale\',
);

$films = new WP_Query($args);

// If there\'s posts, show it
if($films->have_posts())
{
    while($films->have_posts())
    {
        $films->the_post();
        the_title();
        the_content();      
    }
}

// Reset query
wp_reset_query();
