在WooCommerce结帐页面上显示产品类别

Question

我正在尝试将产品类别添加到下面的（有效）代码中，但不确定如何去做。

我曾尝试使用product_cat，但由于我对php的经验不足，我只是在猜测如何实现此目标。

add_filter( 'woocommerce_get_item_data', 'display_custom_product_field_data', 10, 2 );
function display_custom_product_field_data( $cart_data, $cart_item ) {
    $meta_keys = array('time','date');
    $dictionary = array('time'=>'Time:','date'=>'Date:' );
$product_id = $cart_item['product_id'];

foreach($meta_keys as $key=>$meta_key){

$meta_value = get_post_meta( $product_id, $meta_key, true );

if( !empty( $cart_data ) )
    $custom_items = $cart_data;

if( !empty($meta_value) ) {
    $custom_items[] = array(
        'key'       => __( $dictionary[$meta_key] , 'woocommerce'), //or user $meta_key
        'value'     => $meta_value,
        'display'   => $meta_value,
    );
}
}
return $custom_items;
}

以下代码还将显示类别

function display_custom_product_field_data( $cart_data, $cart_item ) {
    $meta_keys = array( 'time', 'date' );
    $dictionary = array( 'time' => 'Time:', 'date' => 'Date:' );

    // Product ID
    $product_id = $cart_item['product_id'];

    // Get terms
    $term_names = wp_get_post_terms( $product_id, 'product_cat', ['fields' => 'names'] );

    foreach( $meta_keys as $key => $meta_key) {

        $meta_value = get_post_meta( $product_id, $meta_key, true );

        if( ! empty( $cart_data ) ) $custom_items = $cart_data;

        $meta_value = 'abc';

        if( ! empty( $meta_value ) ) {
            $custom_items[] = array(
                'key'       => __( $dictionary[$meta_key] , 'woocommerce'), //or user $meta_key
                'value'     => $meta_value,
                'display'   => $meta_value,
            );
        }   
    }

    if( ! empty( $term_names ) ) {
        $custom_items[] = array(
            'name'       => __( 'Categories' , 'woocommerce'), //or user $meta_key
            'value'   => implode( ", ", $term_names )
        );
    }   

    return $custom_items;
}
add_filter( 'woocommerce_get_item_data', 'display_custom_product_field_data', 10, 2 );
