Introduction: WooCommerce is a powerful e-commerce platform, but sometimes customizing its templates can be a bit tricky. One common issue users face is trying to display product thumbnails in customer email notifications. In this step-by-step guide, we’ll address a specific user’s problem and provide an easy solution.

Problem Description: User ID: 169356 has overridden the WooCommerce template file email-order-details to display product thumbnails in customer emails. However, they’re encountering an issue where only white space is displayed in the received email.

Solution: Using the woocommerce_email_order_items_args Filter

  1. Understanding the Problem: The code snippet provided by User ID: 169356 is not achieving the desired result. The issue lies in how product thumbnails are being handled.
  2. A Better Approach: User ID: 177097 suggests using the woocommerce_email_order_items_args filter, which allows us to modify the arguments used for displaying order items in emails.
  3. Implementation: To implement this solution, follow these steps:

    a. Open your theme’s functions.php file.

    b. Add the following code at the end of the file:

    function add_product_thumbnail_to_wc_emails( $args ) {
        $args['show_image'] = true;
        $args['image_size'] = array( 100, 100 );
        return $args;
    add_filter( 'woocommerce_email_order_items_args', 'add_product_thumbnail_to_wc_emails' );
    1. This code hooks into the woocommerce_email_order_items_args filter and modifies the arguments to include product thumbnails.
    2. Save Changes: Save the changes to your functions.php file.
    3. Test: Place a test order and check the email notification. You should now see the product thumbnails correctly.

    Explanation: The woocommerce_email_order_items_args filter allows us to customize the arguments used when generating the order items in emails. By modifying the show_image and image_size parameters, we ensure that product thumbnails are included in the email.

    Conclusion: Customizing WooCommerce templates can be challenging, but with the right filters and hooks, you can achieve the desired results. In this case, using the woocommerce_email_order_items_args filter provides a cleaner and more effective solution to display product thumbnails in customer email notifications.
