In WooCommerce, I am trying to send an email notification to the customer, when an order has a status "cancelled".

Here is my code placed in my child theme's function.php file:

add_filter('woocommerce_order_status_changed', 'send_mail_abandonned_order', 10, 4);
function woocommerce_send_mail_abandonned_order($order, $new_status)
{
    if (!$order ||  $new_status != 'cancelled') return;
    print("Entering in function"); //nothing append
    throw new("error"); // Nothing append  
    //$order = new WC_Order($order_id);
    $order = wc_get_order($order);
    if ( $new_status == 'cancelled' ) {
        //$customer_email = $order->get_billing_email(); // The customer email
        ob_start();
        include( 'email/mail.php' );
        $message =  ob_get_clean();
        define("HTML_EMAIL_HEADERS", array('Content-Type: text/html; charset=UTF-8'));
        // Get woocommerce mailer from instance
        $mailer = WC()->mailer();
        // Wrap message using woocommerce html email template
        $wrapped_message = $mailer->wrap_message("Vous n'avez pas oublié quelque chose ?", $message);
        // Create new WC_Email instance
        $wc_email = new WC_Email;
        // Style the wrapped message with woocommerce inline styles
        $html_message = $wc_email->style_inline($wrapped_message);
        // Send the email using wordpress mail function
        wp_mail( "[email protected]", 'Oups Vous n\'avez pas oubliez quelque chose ?', $html_message, HTML_EMAIL_HEADERS );
    } 
}

But I don't know why this hook is not working properly. When I change the order status to cancelled and try to throw an error, nothing is appended to my php errors logs. It seems that this hook is not working.

A better solution will be to use all arguments included in woocommerce_order_status_cancelled hooked function, so the missing $order variable.

Also as the action hook woocommerce_order_status_cancelled is triggered when order status change to "cancelled", so in your code, if ($order->has_status('cancelled')) { is not needed.

Then your code will be:

add_filter('woocommerce_order_status_cancelled', 'woocommerce_send_mail_abandonned_order', 10, 2 );
function woocommerce_send_mail_abandonned_order( $order_id, $order )
{
    define("HTML_EMAIL_HEADERS", array('Content-Type: text/html; charset=UTF-8'));

    // Get WooCommerce mailer from instance
    $mailer = WC()->mailer();

    ob_start();
    include( 'email/mail.php' );
    $message = ob_get_clean();

    // Wrap message using woocommerce html email template
    $wrapped_message = $mailer->wrap_message("Vous n'avez pas oublié quelque chose ?", $message);

    // Create new WC_Email instance
    $wc_email = new WC_Email;

    // Style the wrapped message with woocommerce inline styles
    $html_message = $wc_email->style_inline($wrapped_message);

    // Send the email using wordpress mail function
    wp_mail( $order->get_billing_email(), 'Oups Vous n\'avez pas oubliez quelque chose ?', $html_message, HTML_EMAIL_HEADERS );
}

Or with woocommerce_order_status_changed hook (your question hook):

add_filter('woocommerce_order_status_changed', 'woocommerce_send_mail_abandonned_order', 10, 4 );
function woocommerce_send_mail_abandonned_order(  $order_id, $old_status, $new_status, $order )
{
    if ( $new_status === 'cancelled') 
    {
        define("HTML_EMAIL_HEADERS", array('Content-Type: text/html; charset=UTF-8'));

        // Get WooCommerce mailer from instance
        $mailer = WC()->mailer();

        ob_start();
        include( 'email/mail.php' );
        $message = ob_get_clean();

        // Wrap message using woocommerce html email template
        $wrapped_message = $mailer->wrap_message("Vous n'avez pas oublié quelque chose ?", $message);

        // Create new WC_Email instance
        $wc_email = new WC_Email;

        // Style the wrapped message with woocommerce inline styles
        $html_message = $wc_email->style_inline($wrapped_message);

        // Send the email using wordpress mail function
        wp_mail( $order->get_billing_email(), 'Oups Vous n\'avez pas oubliez quelque chose ?', $html_message, HTML_EMAIL_HEADERS );
    }
}

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

Here is the solution...

// CHANGE THE HOOK DESCRIPTION
add_filter('woocommerce_order_status_cancelled', 'woocommerce_send_mail_abandonned_order',21, 1);
function woocommerce_send_mail_abandonned_order($order_id)
{
    if (!$order_id) return;
    $order = wc_get_order($order_id);
    if ($order->has_status('cancelled')) {
        //$customer_email = $order->get_billing_email(); // The customer email
        ob_start();
        include( 'email/mail.php' );
        $message =  ob_get_clean();
        define("HTML_EMAIL_HEADERS", array('Content-Type: text/html; charset=UTF-8'));
        // Get woocommerce mailer from instance
        $mailer = WC()->mailer();
        // Wrap message using woocommerce html email template
        $wrapped_message = $mailer->wrap_message("Vous n'avez pas oublié quelque chose ?", $message);
        // Create new WC_Email instance
        $wc_email = new WC_Email;
        // Style the wrapped message with woocommerce inline styles
        $html_message = $wc_email->style_inline($wrapped_message);
        // Send the email using wordpress mail function
        wp_mail( "[email protected]", 'Oups Vous n\'avez pas oubliez quelque chose ?', $html_message, HTML_EMAIL_HEADERS );
    } 
}

Change $order by $order_id too
