php wordpress woocommerce orders email-notifications

Stop send specific email notification for specific users in Woocommerce

I want to stop send Woocommerce email for specific user/email. this is my example code to stop send email when order is completed.

<?php
add_filter( 'woocommerce_email_headers', 'ieo_ignore_function', 10, 2);

function ieo_ignore_function($headers, $email_id, $order) {
    $list = '[email protected],[email protected]';
    $user_email = (method_exists( $order, 'get_billing_email' ))? $order->get_billing_email(): $order->billing_email;
    $email_class = wc()->mailer();
    if($email_id == 'customer_completed_order'){
        if(stripos($list, $user_email)!==false){
            remove_action( 'woocommerce_order_status_completed_notification', array( $email_class->emails['WC_Email_Customer_Completed_Order'], 'trigger' ) );
        }
    }
}

But WP keep send the email. I try to search in Woocommerce docs and source (github) and Stackoverflow also but still cant solve this.

Solution

In this example "Customer completed order" notification is disable for specific customer email addresses:

// Disable "Customer completed order" for specifics emails
add_filter( 'woocommerce_email_recipient_customer_completed_order', 'completed_email_recipient_customization', 10, 2 );
function completed_email_recipient_customization( $recipient, $order ) {
    // Disable "Customer completed order
    if( is_a('WC_Order', $order) && in_array($order->get_billing_email(), array('[email protected]','[email protected]') ) ){
        $recipient = '';
    }
    return $recipient;
}

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

Note: A filter hook needs always to return the filtered main function argument

It can also be done from User IDs like:

// Disable "Customer completed order" for specifics User IDs
add_filter( 'woocommerce_email_recipient_customer_completed_order', 'completed_email_recipient_customization', 10, 2 );
function completed_email_recipient_customization( $recipient, $order ) {
    // Disable "Customer completed order
    if( is_a('WC_Order', $order) && in_array($order->get_customer_id(), array(25,87) ) ){
        $recipient = '';
    }
    return $recipient;
}

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