Let’s delve into one of the essential WooCommerce
Hook : woocommerce_checkout_update_order_meta
The woocommerce_checkout_update_order_meta hook is an action hook in WooCommerce that allows developers to update order meta data during the checkout process. This hook fires after the order has been created but before the customer is redirected to the thank you page. It provides an opportunity to manipulate or add additional data to the order meta, which can be useful for various purposes such as tracking, customizing order details, or integrating with external systems.
/**
* Update order meta data during checkout.
*
* @param int $order_id Order ID.
*/
function custom_update_order_meta( $order_id ) {
// Retrieve the order object
$order = wc_get_order( $order_id );
// Example: Add custom meta data to the order
$order->update_meta_data( 'custom_key', 'custom_value' );
// Save the data
$order->save();
}
add_action( 'woocommerce_checkout_update_order_meta', 'custom_update_order_meta' );In the example above, we define a function custom_update_order_meta hooked into woocommerce_checkout_update_order_meta. This function receives the order ID as a parameter. Inside the function:
We retrieve the order object using wc_get_order() function.
We then use the update_meta_data method of the order object to add custom meta data. In this example, we’re adding a custom key-value pair (custom_key and custom_value) to the order meta.
Finally, we save the order object using the save method to persist the changes.
Use Cases:

Integration with External Systems : It provides an opportunity to integrate WooCommerce with external systems or services by passing additional order data.

Best Practices :

Keep Customizations Minimal : Only add necessary meta data to keep the order information concise and manageable.
Document Customizations : Document any customizations made using this hook for future reference and maintenance.
