Add a custom field to an order in WooCommerce 3+

In WooCommerce, I would like to add a new custom field to order details. I now that I can use use the code below to create a new custom field ‘referenceNumber’ and adds in it "ordercreated" value:

update_post_meta($order_id, 'referenceNumber', 'ordercreated']);

What I would like is to make that through checkout once an order is placed.

But it doesn’t work it doesn’t add a new custom field to order details page and don’t add the value ‘ordercreated’, as you can see in this screenshot:

So the question is how to add a custom field when an order is placed in WooCommerce?

    To add a custom field to an order you can use:

    • WordPress update_post_meta() function (from an order id):

      $order_id = $order->get_id(); // If needed

update_post_meta($order_id, 'referenceNumber', 'ordercreated'); // add and save the custom field

    • WooCommerce WC_Data update_meta_data() method (from the order object or the order id):

      $order = wc_get_order( $order_id ); // If needed: Get the WC_Order object from the order Id

update_meta_data('referenceNumber', 'ordercreated'); // Add the custom field

$order->save(); // Save the data

    Where referenceNumber is the meta key and ordercreated is the meta value. Both works.

    Now to add a custom field to an order when customer place an order, you can use:

    • woocommerce_checkout_create_order action hook (before order data is saved – used to adjust order data before it’s saved):

      add_action( 'woocommerce_checkout_create_order', 'add_custom_field_on_placed_order', 10, 2 );
function add_custom_field_on_placed_order( $order, $data ){
    $order->update_meta_data( 'referenceNumber', 'ordercreated' );
}

    • woocommerce_checkout_update_order_meta action hook (order already exist – used to add custom meta data):

      add_action( 'woocommerce_checkout_create_order', 'add_custom_field_on_placed_order', 10, 2 );
function add_custom_field_on_placed_order( $order_id, $data ){
    $order->update_meta_data( 'referenceNumber', 'ordercreated' );
}

    • woocommerce_checkout_order_created action hook (order already exist – to trigger an action or also to add custom meta data):

      add_action( 'woocommerce_checkout_order_created', 'add_custom_field_on_placed_order', 10, 2 );
function add_custom_field_on_placed_order( $order_id, $data ){
    $order->update_meta_data( 'referenceNumber', 'ordercreated' ); // Add the custom field
    $order->save(); // Save data (as order exist yet)
}

      Or:

      add_action( 'woocommerce_checkout_order_created', 'add_custom_field_on_placed_order' );
function add_custom_field_on_placed_order( $order ){
    update_post_meta($order->get_id(), 'referenceNumber', 'ordercreated');
}

    Code goes in functions.php file of your active child theme (or active theme). Tested and works.
