How to get the category title in a post in Wordpress?
提问by Keith Donegan
Say I have a post called Hello World in Wordpress and I'm directly viewing this page, how would I go about finding the category of "Hello World" and displaying it?
假设我在 Wordpress 中有一篇名为 Hello World 的帖子，并且我正在直接查看此页面，我将如何查找“Hello World”的类别并显示它？

Use get_the_category()like this:
get_the_category()像这样使用：
<?php
foreach((get_the_category()) as $category) {
echo $category->cat_name . ' ';
}
?>
It returns a list because a post can have more than one category.
它返回一个列表，因为一篇文章可以有多个类别。
The documentationalso explains how to do this from outside the loop.
该文档还解释了如何从循环外执行此操作。

You can use
您可以使用
<?php the_category(', '); ?>
which would output them in a comma separated list.
这将在逗号分隔列表中输出它们。
You can also do the same for tags as well:
您也可以对标签执行相同的操作：
<?php the_tags('<em>:</em>', ', ', ''); ?>
