如何在WordPress模板中获取父类别名称？我可以按父类别查询帖子吗？ [英] How do I get the parent category name in WordPress template? And can I query post by the parent category?

问题描述

我尝试在WordPress论坛上获得帮助，但没有运气。无论如何，这是我的问题...

I tried getting help on the WordPress forums but no luck. Anyways, here is my question...

可以说我要为每个父级创建10个父类别和2个子类别。我的WordPress帖子属于特定父类别的一个子类别

Lets say I am creating 10 parent categories and 2 sub categories to each parent. My WordPress post belongs to one sub category of a particular parent category

如何仅获取父类别名称？我不需要子类别名称？

How do I get the parent category name ONLY? I don't want subcategories names? what WordPress code would do that?

还有一个问题...

是否可以查询帖子？由子类别的父项使用：

Is it possible to query post by the parent of a sub category by using:

，而不是输入 cat = 1 或特定类别的名称，我可以做类似的事情：

but instead of entering cat=1 or the name of the particular category, can I do something like:

这样，它将自动插入并查询帖子

So this way it would automatically insert and query post for the parent of any particular sub category that's clicked on?

推荐答案

要获得父类别名称，请使用 get_cat_name（）函数，将父级作为参数-像这样：

To get the parent category name, use the get_cat_name() function, with the parent as the parameter -- like so:

$cat = get_the_category();
$parentCatName = get_cat_name($cat[0]->parent);
