WooCommerce - Adding product category to order-det

Question

---

Here's what I'm attempting to do and where.

In the check out process for an order, in the plug-in WooCommerce; you are taken to a page when the check out is process is complete. It displays an overview of the order details. The template file used to output this page is order-details.php.

Here's what I'd like to add

I would like to display the product's product category like so:

This is area of code I'm attempting to add to, the first section of the order details table.

<tbody>
    <?php
    if ( sizeof( $order->get_items() ) > 0 ) {

        foreach( $order->get_items() as $item ) {
            $_product     = apply_filters( 'woocommerce_order_item_product', $order->get_product_from_item( $item ), $item );
            $item_meta    = new WC_Order_Item_Meta( $item['item_meta'], $_product );

            ?>
            <tr class="<?php echo esc_attr( apply_filters( 'woocommerce_order_item_class', 'order_item', $item, $order ) ); ?>">
                <td class="product-name">
                    <?php
                        if ( $_product && ! $_product->is_visible() )
                            echo apply_filters( 'woocommerce_order_item_name', $item['name'], $item );
                        else
                            echo apply_filters( 'woocommerce_order_item_name', sprintf( '<a href="%s">%s</a>', get_permalink( $item['product_id'] ), $item['name'] ), $item );

                        echo apply_filters( 'woocommerce_order_item_quantity_html', ' <strong class="product-quantity">' . sprintf( '&times; %s', $item['qty'] ) . '</strong>', $item );

This is my understanding so far;

• That a custom query is being applied.
• That for each product listed details are being echoed.
• That a WooCommerce Class is being used to get specific product meta.

My understandings are observations at my current knowledge level.

What I was hoping was that I could use something like

echo apply_filters( 'woocommerce_order_item_name', ' <strong class="product-category">' . e_( $item['product_cat'] ) . '</strong>', $item );

I can't find a more relevant filter and I'm really not sure that ['product_cat'] is even relevant here. This is an example of the way I'm attempting to solve my requirement.

As you can tell, I don't work in PHP full time. I'm learning as much as I can when I can. Advise would be greatly appreciated

This is how you might add the product categories to the Product title. I don't particularly like how it is outputting for me, but then I am testing it on a variable subscription, so that is amending its own data. This would go in your theme's functions.php

function kia_woocommerce_order_item_name( $name, $item ){

    $product_id = $item['product_id'];
    $tax = 'product_cat';

    $terms = wp_get_post_terms( $product_id, $tax, array( 'fields' => 'names' ) );

    if( $terms && ! is_wp_error( $terms )) {
        $taxonomy = get_taxonomy($tax);
        $name .= '<label>' . $taxonomy->label . ': </label>' . implode( ', ', $terms );
    }

    return $name;
}
add_filter( 'woocommerce_order_item_name', 'kia_woocommerce_order_item_name', 10, 2 );

Otherwise you could copy the order-details.php template into your own theme (so yourtheme/woocommerce/order/order-details.php and add the code directly. This would give you more control over where you want the category to appear since there aren't a lot of hooks available in this section, but put you at risk if WooCommerce ever modifies this code. I have worked on a few sites that broke because the the theme was using outdated template.

Any way, an example would be:

<?php
/**
 * Order details
 *
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     2.2.0
 */

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

global $woocommerce;

$order = new WC_Order( $order_id );
?>
<h2><?php _e( 'Order Details', 'woocommerce' ); ?></h2>
<table class="shop_table order_details">
    <thead>
        <tr>
            <th class="product-name"><?php _e( 'Product', 'woocommerce' ); ?></th>
            <th class="product-total"><?php _e( 'Total', 'woocommerce' ); ?></th>
        </tr>
    </thead>
    <tfoot>
    <?php
        if ( $totals = $order->get_order_item_totals() ) foreach ( $totals as $total ) :
            ?>
            <tr>
                <th scope="row"><?php echo $total['label']; ?></th>
                <td><?php echo $total['value']; ?></td>
            </tr>
            <?php
        endforeach;
    ?>
    </tfoot>
    <tbody>
        <?php
        if ( sizeof( $order->get_items() ) > 0 ) {

            foreach( $order->get_items() as $item ) {
                $_product     = apply_filters( 'woocommerce_order_item_product', $order->get_product_from_item( $item ), $item );
                $item_meta    = new WC_Order_Item_Meta( $item['item_meta'], $_product );

                ?>
                <tr class="<?php echo esc_attr( apply_filters( 'woocommerce_order_item_class', 'order_item', $item, $order ) ); ?>">
                    <td class="product-name">
                        <?php
                            if ( $_product && ! $_product->is_visible() )
                                echo apply_filters( 'woocommerce_order_item_name', $item['name'], $item );
                            else
                                echo apply_filters( 'woocommerce_order_item_name', sprintf( '<a href="%s">%s</a>', get_permalink( $item['product_id'] ), $item['name'] ), $item );

                            echo apply_filters( 'woocommerce_order_item_quantity_html', ' <strong class="product-quantity">' . sprintf( '&times; %s', $item['qty'] ) . '</strong>', $item );
