Woocommerce: append atribute value to order-notes

Question

I'm trying to append the atribute value of pa-lager to delieverynotes and invoices. I'm working from this answer.

This is what I have:

function lager_placering( $product ) {
 if( isset( $product->id ) ) {
$lager = $product->get_attribute('pa_lager');
//echo $lager;
}
}

add_action( 'wcdn_order_item_after', 'lager_placering' );

It does not work. at all.

Answer 1

This works like a charm

function lager_placering( $product ) {
$lager = $product->get_attribute('pa_lager');
echo $lager;
}
add_action( 'wcdn_order_item_after', 'lager_placering' );
