How do I get the parent category name in WordPress template? And can I query post by the parent category?
提问by
I tried getting help on the WordPress forums but no luck. Anyways, here is my question...
我尝试在 WordPress 论坛上寻求帮助，但没有成功。无论如何，这是我的问题......
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
假设我正在为每个父级创建 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
How do I get the parent category name ONLY? I don't want subcategories names? what WordPress code would do that?
如何仅获取父类别名称？我不想要子类别名称？什么 WordPress 代码会做到这一点？
And one more question...
还有一个问题……
Is it possible to query post by the parent of a sub category by using:
是否可以使用以下方法查询子类别的父级的帖子：
but instead of entering cat=1or the name of the particular category, can I do something like:
但不是输入cat=1特定类别的名称，而是我可以执行以下操作：
So this way it would automatically insert and query post for the parent of any particular sub category that's clicked on?
所以这样它会自动插入和查询被点击的任何特定子类别的父级的帖子？

To get the parent category name, use the get_cat_name()function, with the parent as the parameter -- like so:
要获取父类别名称，请使用该get_cat_name()函数，以父类别作为参数——像这样：
$cat = get_the_category();
$parentCatName = get_cat_name($cat[0]->parent);

All these answers failed for me.
所有这些答案对我来说都失败了。
I eventually managed to display a post's topmost category name like this :
我最终设法像这样显示帖子的最顶层类别名称：
$categories = get_the_category();
$category= '';
foreach($categories as $childcat) {
$parentcat = $childcat->category_parent;
if($parentcat>0){
$category = get_cat_name($parentcat);
continue;
}
}
$category = (strlen($category)>0)? $category : $categories[0]->cat_name;

Found this answer, which gives you the first ancestor slug. It could easily be modified to give you the name.
找到了这个答案，它为您提供了第一个祖先蛞蝓。它可以很容易地修改为给你的名字。
Got it here: http://nick.boldison.com/wordpress/wordpress-get-top-level-parent-category/
在这里得到它：http: //nick.boldison.com/wordpress/wordpress-get-top-level-parent-category/
<?php
// get parent category slug
$parentCatList = get_category_parents($cat,false,',');
$parentCatListArray = split(",",$parentCatList);
$topParentName = $parentCatListArray[0];
$sdacReplace = array(" " => "-", "(" => "", ")" => "");
$topParent = strtolower(strtr($topParentName,$sdacReplace));
?>
In fact, to get the parent name:
实际上，要获取父名称：
// get parent category slug
$parentCatList = get_category_parents($cat,false,',');
$parentCatListArray = split(",",$parentCatList);
$topParentName = $parentCatListArray[0];
