在年份和月份标题下显示每个分类术语帖子

Question

我有一个 CPT - 'newsletters' 和 Taxonomy 'newsletter-groups'

我正在尝试在其各自的术语标题下显示每个帖子，并在其下显示所有术语帖子，显示它们发布的月份和年份（按发布日期）。

我以为我有一些工作，但在测试过程中注意到，如果一个帖子有相同的“月份”，它将消除同一期限内其他帖子的年份和月份以及它下面的条款，我有一些图片来显示我的意思以及我目前使用的代码。

在显示的图像中，为清楚起见，我已将发布日期附加到文件名中，通常只是文件名。

如果发布日期月份相同，则不工作

在发布日期月份不同时工作

我该如何解决这个问题？我是否需要通过单独的查询获取所有发布日期并保存？

任何例子表示赞赏

  } // end for each

} // end function 

genesis(); // call genesis framework

去掉 if 和 else 两个条件，尝试只打印 echo ''; the_date('F Y');回声''

它只会显示单个发布日期 - 但不会分组

您可以将每个月推送到数组中，并检查月份是否已经在数组中，然后不显示重复月份。
