I'm customizing woocommerce to create a food reservation system. I've successfully removed all unnecessary checkout fields and I've disabled the payments gateway because I just need to register the order. I'm now adding some custom fields to the checkout page using elementor and a custom plugin I'm writing. I have this code ath the moment and I need to customize the checkout, when a client place a reservation (order), I will need to send an email to some custom email adresses that can be selected from the user using a custom checkout field I've added. Is possible to automatically change the order status to completed and send the email, and what is the hook to use?

$checkout = new CustomCheckout();
1. Hook into the woocommerce_thankyou action:
This action fires when an order is placed successfully, making it ideal for handling post-order tasks like status changes and email notifications.
2. Modify your send_order_status_change_email method:
public function send_order_status_change_email( $order_id ) {
$order = wc_get_order( $order_id );
// Get the selected email address from the custom field
$selected_email = $order->get_meta( 'pdvselector' );
// Change the order status to completed
$order->update_status( 'completed' );
// Send the email notification to the selected address
WC()->mailer()->send( 'customer_completed_order', $order_id, $selected_email );
}
3. Add the action hook in your CustomCheckout constructor:
public function __construct() {
//add this line
add_action( 'woocommerce_thankyou', array( $this, 'send_order_status_change_email' ), 10, 1 );
}
When a customer places an order, the send_order_status_change_email method will be triggered. It will retrieve the selected email address from the pdvselector custom field. The order status will be updated to "completed". The "customer_completed_order" email template will be sent to the selected email address, informing them of the reservation.
EDIT 1
You can avoid sending two emails by utilizing a different hook and making some adjustments to your code.
1. Hook into woocommerce_order_status_changed:
Instead of using woocommerce_thankyou, leverage the woocommerce_order_status_changed action. This fires whenever the order status changes, allowing you to capture the completion moment without relying on the checkout page completion.
2. Refine your send_order_status_change_email method:
Modify your existing method to check the new order status before sending the email.
public function send_order_status_change_email( $order_id, $old_status, $new_status ) {
if ( $new_status !== 'completed' ) {
return; // Do not send email if not completed
}
$order = wc_get_order( $order_id );
// ... Get selected email and send email logic ...
}
3. Register the action hook:
Update your constructor's code to register the hook with the updated method:
public function __construct() {
//add this line
add_action( 'woocommerce_order_status_changed', array( $this, 'send_order_status_change_email' ), 10, 3 );
}
With this, the email will only be sent when the order status changes to "completed," effectively preventing duplicate emails and confirming the successful order completion to the selected email address.
