Introduction

If you're using WooCommerce and handling categories, you may have encountered the need to personalize your order confirmation emails. Specifically, one common requirement is to display sub-categories relating to a specific parent category. This is particularly useful when you want to communicate pertinent information to customers about products they’ve ordered.

In this guide, we will walk you through the process of modifying your WooCommerce order emails to include only the sub-categories from a selected parent category—in our case, the Brands category.

The Challenge

In our scenario, there are two main categories in WooCommerce: Brands and Categories. You want to display only the sub-categories assigned to products that fall under the Brands category, which has the parent ID of 15. This customization requires some code modifications to filter the correct categories before presenting them in the order emails.



Solution Breakdown

To solve this problem, we'll use a code snippet that updates how the order item name is displayed in WooCommerce emails. The following steps will guide you through the implementation:

Step 1: Understand the Basic Code

The code you provided is already functional but displays all categories assigned to a product. Here’s the initial version of the code:

Step 2: Modify the Code to Filter Specific Parent Categories

To restrict the output to only sub-categories of the Brands category, we need to introduce a condition to skip terms that don’t have the parent ID of 15. Here’s how the modified code looks:

This code checks the parent of each term and continues to the next iteration if the term isn’t a child of the desired parent (with an ID of 15).



Conclusion

By implementing this code modification in your WooCommerce site, you can tailor your order confirmation emails to show only the relevant sub-categories from a specific parent category. This helps improve customer communication and ensures your emails maintain clarity and relevance.
