WooCommerce new order action - get order information - php

Question

I am using this to create a new function in my functions.php file
add_action( 'woocommerce_new_order', 'create_invoice_for_wc_order', 1, 1 );
function create_invoice_for_wc_order() {
}
it is to execute some custom code when a new order is placed, how can i get the order information (ordered products etc) inside my function

Answer 1

You can use $order_id as a parameter for your woocommerce_new_order callback and get the order details from the $order_id.
Example:
// define the woocommerce_new_order callback
function create_invoice_for_wc_order( $order_id ) {
// get order details data...
$order = new WC_Order( $order_id );
var_dump($order);
};

Answer 2

All answers here are correct but if you need the line items the above wont work since line items can't be fetched with new WC_Order at that time.
The hook now has a second $order parameter that will work.
add_action( 'woocommerce_new_order', 'create_invoice_for_wc_order', 1, 2 );
function create_invoice_for_wc_order( $order_id, $order ) {
$items = $order->get_items();
// etc...
}

woocommerce_new_order includes an $order_id parameter. You can use it in your callback:
add_action( 'woocommerce_new_order', 'create_invoice_for_wc_order', 1, 1 );
function create_invoice_for_wc_order( $order_id ) {
$order = new WC_Order( $order_id );
$items = $order->get_items();
// etc...
}

If you want to get only the order details, You can use 'woocommerce_new_order' hook and $order_id as parameter
add_action( 'woocommerce_new_order', 'create_invoice_for_wc_order', 1, 1 );
function create_invoice_for_wc_order($order_id) {
$order = new WC_Order( $order_id );
print_r($order);
//your code
}
But if You want to get order items You should use 'woocommerce_checkout_order_processed'
add_action( 'woocommerce_checkout_order_processed', 'create_invoice_for_wc_order', 1, 1 );
function create_invoice_for_wc_order($order_id) {
$order = new WC_Order( $order_id );
//order items
$items = $order->get_items();
print_r($items);
}
