在Woocommerce中检查产品类别的产品 [英] Check a product category for a product in Woocommerce

问题描述

我想在创建(或更新)WooCommerce产品信息后立即检查其类别，然后根据该类别运行更多代码.

I want to check the category of a WooCommerce product post right after it's created(or updated) and then run some more code based on the category.

要检查有关创建/更新的帖子，我使用了 save_post ，并使用了类别 has_category . has_category 出了点问题，它根本不返回任何内容.我尝试按照其他问题中的建议用 $ post 和 $ post-> ID 替换 $ post_id ，但这并没有改变.

To check post on creation/update I used save_post and for category has_category. Something goes wrong with has_category and it doesn't return anything at all. I tried replacing $post_id with $post and $post->ID as suggested in other issues but that didn't change anything.

function doFruitStuff($post_id){ // Function in functions.php
    $fruits = 'fruits';
    if(has_category($fruits, $post_id)){
    echo "<script type='text/javascript'>alert('has the category');</script>";
}else{
    echo "<script type='text/javascript'>alert('doesnt have the category');</script>";
}}
add_action('save_post', 'doFruitStuff');

我使用 has_category 的方式有误还是WooCommerce产品类别的工作方式不同?

Am I using has_category incorrectly or WooCommerce product categories work differently?

我曾经在javascript警报中调试过，对此感到抱歉.任何帮助都将不胜感激.

I'm used to debugging in javascript alerts, sorry about that. Any help greatly appreciated.

推荐答案

您不能使用 has_category() Wordpress函数检查Woocommerce产品类别.

You can't use has_category() Wordpress function to check Woocommerce product categories.

注意:产品类别是Woocommerce使用的自定义分类法.

Note: Product category is a custom taxonomy used by Woocommerce.

因此，您需要使用 has_term() 与Woocommerce产品类别的这种方式:

So instead you will need to use has_term() with Woocommerce product categories this way:

add_action('save_post', 'do_fruit_stuff');
function do_fruit_stuff( $post_id ){
    $terms = array('fruits');
    if( has_term( $terms, 'product_cat', $post_id ) ){
        echo "<script type='text/javascript'>alert('has the product category');</script>";
    }else{
        echo "<script type='text/javascript'>alert('doesnt have the product category');</script>";
    }
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.

Code goes in function.php file of your active child theme (or active theme). Tested and works.

注意:用于Woocommerce产品类别的自定义分类法是" product_cat ".

Note: The custom taxonomy used for Woocommerce product categories is "product_cat".
