Display a product custom field value in WooCommerce cart and checkout table

Question

In WooCommerce and I have added a custom field "description" for each product. I was able to find a way to show both, the label name and the value:

add_filter( 'woocommerce_add_cart_item_data', 'save_days_field', 10, 2 );
function save_days_field( $cart_item_data, $product_id ) {
    $special_item = get_post_meta( $product_id , 'description',true );

    if(!empty($special_item)) {
        $cart_item_data[ 'description' ] = $special_item;

        // below statement make sure every add to cart action as unique line item
        $cart_item_data['unique_key'] = md5( microtime().rand() );
        WC()->session->set( 'description', $special_item );
    }
    return $cart_item_data;
}

// Render meta on cart and checkout
add_filter( 'woocommerce_get_item_data','rendering_meta_field_on_cart_and_checkout', 10, 2 );
function rendering_meta_field_on_cart_and_checkout( $cart_item_data, $cart_item ) {
    if( isset( $cart_item['description'] ) ) {
        $cart_item_data[] = array( "name" => __( "Description", "woocommerce" ), "value" => $cart_item['description'] );
    }
    return $cart_item_data;
}

Now I need to display ONLY the value (not the label name "Description") of this custom field in the cart and checkout table. I need to display with <small>, like the attribute I am displaying with this code:

add_filter('woocommerce_cart_item_name', 'wp_woo_cart_attributes', 10, 2);
function wp_woo_cart_attributes($cart_item, $cart_item_key){
    $productId = $cart_item_key['product_id'];
    $product = wc_get_product($productId);
    $taxonomy = 'pa_color';
    $value = $product->get_attribute($taxonomy);

    if ($value) {
        $label = get_taxonomy($taxonomy)->labels->singular_name;
        $cart_item .= "<small>$value</small>";
    }
    return $cart_item;
}

How can I make it for this custom field, displaying the value only?

If your asking how to do that within the plugin.it is best you look at the documentation for it. Most plugins create a standard "widget" with minimal/base/standard functionality. If people want to expand or customize the widget, you need to edit the php code of the widget. I wouldnt do this without knowing what you are doing providing some code would help — Jujubes

You don't need to include a product custom field as custom cart item data, as it's directly accessible from the product object (or the product ID).

Note: On a cart item variable $cart_item, the WC_Product Object is included and available using $cart_item['data'].

Try the following to add a custom field after the item name in cart and checkout pages:

// Display in cart and checkout pages
add_filter( 'woocommerce_cart_item_name', 'customizing_cart_item_name', 10, 3 );
function customizing_cart_item_name( $product_name, $cart_item, $cart_item_key ) {
    $product = $cart_item['data']; // Get the WC_Product Object

    if ( $value = $product->get_meta('description') ) {
        $product_name .= '<small>'.$value.'</small>';
    }
    return $product_name;
}

To display it on orders and email notifications use:

// Display in orders and email notifications
add_filter( 'woocommerce_order_item_name', 'customizing_order_item_name', 10, 2 );
function customizing_order_item_name( $product_name, $item ) {
    $product = $item->get_product(); // Get the WC_Product Object

    if ( $value = $product->get_meta('description') ) {
        $product_name .= '<small>'.$value.'</small>';
    }
    return $product_name;
}

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