我有以下几点

自定义帖子类型：episode

自定义分类法：series

子条款real deal -> season 1, season 2, season 3, 等等。这些术语是分级的，整个内容的结构就像一部电视剧（每个“系列”都有“季节”）。

在single-episode.php 第页，我想显示当前剧集，以及该季下3集和前3集的链接。

例如，如果在“第1季-第5集”页面上，我需要获取第1季的内容，

第4、3、2集+第1季第6、7、8集。

我很难在单集页面的循环中完成这一点。

这是我目前拥有的内容，但它不起作用——它只是用一个

尝试获取非对象的属性

错误

<小时>EDIT:

这是我更新的查询，仍在进行中。目前似乎没有任何进展。我想得到总共6个结果，3个在当前帖子之前发布，3个在当前帖子之后发布。我正在尝试使用post_date 对于before 和after 的属性date_query 但不确定我是否做对了。

$args = [
    \'tax_query\' => [
      \'relation\' => \'AND\', [
        \'taxonomy\' => \'series\',
        \'field\'    => \'slug\',

        \'terms\'    => [\'season-1\'],
      ]
    ],

EDIT 2:

我用一种效率很低的方法工作，得到了我想要的效果——它是有效的，但我很想听到一些优化它的提示！就目前的查询而言，似乎非常昂贵。
