Add product description to cart items in Woocommerce - php

Question

I'm struggling to find a simple solution to this problem I'm having with One-page-checkout plugin for Woocommerce.
My client would like to add the product description next to the product title in cart items.
Any thoughts on how I can manipulate the code to show the description?
This is what I have actually:
I would think that this plugin would just be hiding the description somewhere but I can't locate it anywhere in the code.

There is 2 ways to do it (making work for products and product variations):
1). With custom function hooked in woocommerce_get_item_data action hook (The best way):
add_filter( 'woocommerce_get_item_data', 'customizing_cart_item_data', 10, 2 );
function customizing_cart_item_data( $cart_data, $cart_item ) {
$description = $cart_item['data']->get_description(); // Get the product description
// For product variations when description is empty
if( $cart_item['variation_id'] > 0 && empty( $description ) ){
// Get the parent variable product object
$parent_product = wc_get_product( $cart_item['product_id'] );
// Get the variable product description
$description = $parent_product->get_description();
}
// If product or variation description exists we display it
if( ! empty( $description ) ){
$cart_data[] = array(
'key' => __( 'Description', 'woocommerce' ),
'value' => $description,
'display' => $description,
);
}
return $cart_data;
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

2). With custom function hooked in woocommerce_cart_item_name filter hook:
WooCommerce: Display also product variation description on cart items

Answer 2

You could try this code in your functions.php located in your root of your theme folder. Not sure if it still works as I'm not active in Wordpress development anymore. [untested]
Updated: this should probably work for WooCommerce 3+
Using woocommerce_cart_item_name hook:
add_filter( 'woocommerce_cart_item_name', 'cart_description', 20, 3);
function cart_description( $name, $cart_item, $cart_item_key ) {
// Get the corresponding WC_Product
$product_item = $cart_item['data'];
if(!empty($product_item)) {
// WC 3+ compatibility
$description = $product_item->get_description();
$result = __( 'Description: ', 'woocommerce' ) . $description;
return $name . '<br>' . $result;
} else
return $name;
}
}
