Display purchase note and attribute on cart and checkout page in WooCommerce - php

Question

The following code works and adds the purchase note to the cart items.
add_filter( 'woocommerce_get_item_data', 'wc_test', 10, 2 );
function wc_test ( $other_data, $cart_item ){
$post_data = get_post( $cart_item['product_id'] );
$other_data[] = array( 'name' => $post_data->_purchase_note );
return $other_data;
}
However, I always get ":" as result, for products that don't have a note.
I also need to add a specific attribute aswell under the note.
Any advice?

The colon is automatically added to the key. Because you only use name, this will be added at the end.
You can use get_purchase_note()
So you get:
// Display on cart & checkout pages
function filter_woocommerce_get_item_data( $item_data, $cart_item ) {
// Get an instance of the WC_Product object
$product = $cart_item['data'];
// Get purchase_note
$purchase_note = $product->get_purchase_note();
// Get the product attribute value (adjust if desired)
$attribute = $product->get_attribute( 'pa_color' );
// When empty
if ( empty ( $attribute ) ) {
$attribute = '';
}
// NOT empty
if ( ! empty( $purchase_note ) ) {
$item_data[] = array(
'key' => __( 'Note', 'woocommerce' ),
'value' => $purchase_note . $attribute,
'display' => $purchase_note . $attribute,
);
}
return $item_data;
}
add_filter( 'woocommerce_get_item_data', 'filter_woocommerce_get_item_data', 10, 2 );
