分类存档，按其他分类分类，不隐藏空分类

时间：2018-03-26 作者：thetwopct

Info about my setup:

<我有一个名为“治疗”的自定义贴子类型，每个治疗最多可分为3个分类类型-治疗类别-“美容沙龙”、“皮肤病”和“spadays”，它们下面有许多不同的类别
  • 治疗也可以附加到品牌，也可以附加到分类-“品牌”

      • What I am trying to achieve:

      在治疗类别存档页面上显示治疗，但按品牌分类法进行划分，还包括类别内未附加到品牌分类法的治疗。因此，归档页面的外观如下所示：

      Treatment Category Title

      Brand 1

      <治疗A治疗B治疗C治疗

      Brand 2

      <治疗D（无品牌）

      我对治疗J进行了分类。php模板在每个分类页面上都会处理这个问题，但是。。。

      My issues are:

      1） 我无法找到阻止显示空治疗类别标题的方法。我想我需要在某处插入foreach或IF语句，或者可能更改$args数组，以便只返回中包含处理的类别。我尝试过包含hide\\u空语句，但这似乎也不起作用。

      2） 当我按品牌分类法设置查询时，我无法显示未附加到任何品牌的治疗方法。也许我需要两个循环？

      这是我的密码，有什么帮助吗？

    1） 解决这个问题非常简单-我将类别名称请求包装在if have_posts 这样就消除了空值

    2） 我必须使用\'operator\' => \'NOT IN\' 列出不在分类中的处理方法。

    我确信有一种更精简、更好的方法来做以下事情，但现在这正是我想要做的。
