Displaying a coupon message on emails for completed order status only

Question

I\'ve got that code that displays a coupon message in the email orders if the customer has not used any in this order.

I would like to display that coupon message on

Answer 1

It is possible easily to display a custom message on emails with an if statement and 2 conditions, for "complete" order status only.

add_action( 'woocommerce_email_before_order_table', 'completed_order_mail_message', 20 );
function completed_order_mail_message( $order ) {
    if ( empty( $order->get_used_coupons() ) && $order->post_status == 'wc-completed' )
        echo '

';
}

This code goes on function.php file of your active child theme or theme

This code is tested and works perfect

BUT to autocomplete paid orders you need to add something:
WooCommerce: Auto complete paid Orders (depending on Payment methods)

Reference:

• Add coupon to the processing order email only if the customer have not used one
• WooCommerce: Auto complete paid Orders (depending on Payment methods)
