WooCommerce: Display also product variation description on cart items

Updated for WooCommerce version 3 and above

Since WooCommerce 3, get_variation_description() is now deprecated and replaced by get_description() WC_Product method.

To get your product item variation description (filtering variation product type condition), you can use the following hooked function instead:

// Cart page (and mini cart)add_filter( 'woocommerce_cart_item_name', 'cart_item_product_description', 20, 3);function cart_item_product_description( $item_name, $cart_item, $cart_item_key ) {    if ( ! is_checkout() ) {        if( $cart_item['variation_id'] > 0 ) {            $description = $cart_item['data']->get_description(); // variation description        } else {            $description = $cart_item['data']->get_short_description(); // product short description (for others)        }        if ( ! empty($description) ) {            return $item_name . '<br><div class="description">                <strong>' . __( 'Description', 'woocommerce' ) . '</strong>: '. $description . '            </div>';        }    }    return $item_name;}// Checkout pageadd_filter( 'woocommerce_checkout_cart_item_quantity', 'cart_item_checkout_product_description', 20, 3);function cart_item_checkout_product_description( $item_quantity, $cart_item, $cart_item_key ) {    if( $cart_item['variation_id'] > 0 ) {        $description = $cart_item['data']->get_description(); // variation description    } else {        $description = $cart_item['data']->get_short_description(); // product short description (for others)    }    if ( ! empty($description) ) {        return $item_quantity . '<br><div class="description">            <strong>' . __( 'Description', 'woocommerce' ) . '</strong>: '. $description . '        </div>';    }    return $item_quantity;}

Now the description is just displayed between the title and the variation attributes values (if there is any).

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

This will work for WC 3.0

    add_filter( 'woocommerce_cart_item_name', 'cart_variation_description', 20, 3);function cart_variation_description( $title, $cart_item, $cart_item_key ) {    $item = $cart_item['data'];    if(!empty($item) && $item->is_type( 'variation' ) ) {        return $item->get_name();    } else        return $title;}

You can get it via global variable $woocommerce also-

global $woocommerce;$cart_data = $woocommerce->cart->get_cart();foreach ($cart_data as $value) {    $_product = $value['data'];    if( $_product->is_type( 'variation' ) ){        echo $_product->id . '<br>';    }}

I already check it.
