Add order items in customer notes field - php

Question

I am trying to add ordered products (quantity per product per line) in customer added notes field for new WooCommerce orders. I introduced the following code in my functions.php but it was not working.
/* Add ordered products to the customer notes field on order creation. */
add_action( ‘woocommerce_new_order’, ‘products_in_customer_notes’, 10, 1 );
function products_in_customer_notes( $order_id ) {
$order = wc_get_order( $order_id );
// Verify it's a WC Order
if ( is_a( $order, 'WC_Order' ) ) {
$customer_note = $order->get_customer_note();
foreach ( $order->get_items() as $item_id => $item ) {
$product_name = $item->get_name();
$quantity = $item->get_quantity();
$customer_note .= "<br>";
$customer_note .= $quantity . 'x ' . $product_name;
}
// Add the note
$order->set_customer_note($customer_note);
// $order->add_order_note($customer_note);
// Save the data
$order->save();
}
}
When that didn't work, I tried to simplify my code by hardcoding a comment instead, but that didn't work either.
/* Add ordered products to the customer notes field on order creation. */
add_action( ‘woocommerce_new_order’, ‘products_in_customer_notes’, 10, 1 );
function products_in_customer_notes( $order_id ) {
$order = wc_get_order( $order_id );
// Verify it's a WC Order
if ( is_a( $order, 'WC_Order' ) ) {
$customer_note = $order->get_customer_note();
$customer_note .= '<br>';
$customer_note .= 'Hardcoded Test';
// foreach ( $order->get_items() as $item_id => $item ) {
// $product_name = $item->get_name();
// $quantity = $item->get_quantity();
// $customer_note .= "<br>";
// $customer_note .= $quantity . 'x ' . $product_name;
// }
// Add the note
$order->set_customer_note($customer_note);
// $order->add_order_note($customer_note);
// Save the data
$order->save();
}
}
What is it that I am missing that is preventing this from working?
The desired output would be something like the following:
Any customer notes if they were inserted at the time of order placement.
1x product A
3x product B
8x product C
etc.

Answer 1

add_action( 'woocommerce_new_order', 'products_in_customer_notes', 10, 2 );
function products_in_customer_notes( $order_id, $order ) {
// Verify it's a WC Order
if ( is_a( $order, 'WC_Order' ) ) {
$customer_note = $order->get_customer_note();
foreach ( $order->get_items() as $item_id => $item ) {
$product_name = $item->get_name();
$quantity = $item->get_quantity();
$customer_note .= "<br>";
$customer_note .= $quantity . 'x ' . $product_name;
}
// Add the note
$order->set_customer_note($customer_note);
// Save the data
$order->save();
}
}
You were missing the parameter count(2), $order_id, $order
