WordPress中是否可以测试一个空术语或类别？ [英] Is it possible in WordPress to test for an empty term or category?

问题描述

我有一个项目，要求我列出每种自定义帖子类型的可用条款，并通过css / javascript直观地指出哪些条款/类别为空。有没有一种方法可以返回术语/类别列表并说将一个类添加到空的术语/类别中？谢谢您的协助。

I have a project that requires me to list out the available terms for each custom post type and indicate visually which of the terms/categories are empty via css/javascript. Is there a way to return a list of terms/categories and say add a class to the empty ones ? Thanks for any and all assistance.

推荐答案

是的。首先，您使用 get_terms（）来获取您的条款（我假设您的cpt具有与其相关的分类法）

Yes there is. First you get your terms using get_terms() (I'm assuming your cpt has associated taxonomy with it)

<?php 

$custom_terms = get_terms('my_taxonomy');

if (is_array($custom_terms) && !empty($custom_terms)) {
    # code what you want here...
} else{
    # code if your terms come empty...
}

这应该做到。

编辑

在 $ custom_terms 变量之后执行a print_r（$ custom_terms）; 来查看变量的含义。您应该得到一个填充有 stdClass对象 s的数组，该分类中的每个类别一个。

After $custom_terms variable do a print_r($custom_terms); to see what the variable holds. You should get an array filled with stdClass Objects, one for each category in this taxonomy.

因此，您可以进一步执行以下操作：

So you can further do something like this:

foreach ($custom_terms as $term) {
    if ($term->count != 0) {
        print_r($term->name);
    }
}

这将向您显示非空类别的名称分类法。

This will show you names of non empty categories in your taxonomy.
