Display coupon usage count and limit in WooCommerce thank you page

Question

I want to display the remaining number of the coupon on the WooCommerce thankyou page

For example: You used the test coupon 3 times and there are 10 more left.

This is my code:

add_action('woocommerce_after_cart_table', 'coupon_count');
function coupon_count() {
    global $woocommerce;

    if ( ! empty( $woocommerce->cart->applied_coupons ) ) {
         $my_coupon = $woocommerce->cart->get_coupons() ;
         foreach($my_coupon as $coupon){

            if ( $post = get_post( $coupon->id ) ) {

                        $counter = $coupon->get_usage_count();
                        echo "<span class='name-coupon'><b>Total usage for coupon </b><b>'</b><b>".$coupon->code."</b><b>'</b><b>: </b></span>";
                        echo "<span class='coupon-counter'>".($counter)."</span>";

            }
        }
    }
}

But I have two problems:

1.With this code, only the number of times used is displayed and the remaining number is not displayed.

2.Replacing woocommerce_after_cart_table with woocommerce_thankyou on the thankyou page does not execute the code.

Instead of using the cart object, the order object is used on the thankyou page. So we're going to use that object instead
You can use get_usage_limit_per_user() to get coupon usage limit per customer (for a single customer)
OR use get_usage_limit() to get coupon usage limit.

So you get:

function action_woocommerce_thankyou( $order_id ) {
    // Get $order object
    $order = wc_get_order( $order_id );

    foreach( $order->get_coupon_codes() as $coupon_code ) {
        // Get the WC_Coupon object
        $coupon = new WC_Coupon( $coupon_code );

        // Get usage count
        $count = $coupon->get_usage_count();
        
        // Get coupon usage limit per customer
        $limit = $coupon->get_usage_limit_per_user();
        
        // OR use this instead, to get coupon usage limit.
        // $limit = $coupon->get_usage_limit();
        
        // NOT empty
        if ( ! empty ( $count ) && ! empty ( $limit ) ) {
            // Calculate remaining
            $remaining = $limit - $count;
        
            // Output
            echo sprintf( '<span class="coupon-class">You used the <strong>%s</strong> coupon <strong>%d</strong> times and there are <strong>%d</strong> more left</span>', $coupon_code, $count, $remaining );
        }
    }
}
add_action( 'woocommerce_thankyou', 'action_woocommerce_thankyou', 10, 1 );

Can I display a list of all users who used this discount code in the same function? — Sinapars, Jan 24 '21 at 09:19
Yes, use [get_used_by()](https://woocommerce.github.io/code-reference/classes/WC-Coupon.html#method_get_used_by) - Get records of all users who have used the current coupon. — 7uc1f3r, Jan 24 '21 at 10:32

add_action('woocommerce_after_cart_table', 'coupon_count');
function coupon_count() {
    global $woocommerce;

    if ( ! empty( $woocommerce->cart->applied_coupons ) ) {
         $my_coupon = $woocommerce->cart->get_coupons() ;
         foreach($my_coupon as $coupon){

            if ( $post = get_post( $coupon->id ) ) {

                        $counter = $coupon->get_usage_count();
                        $remaining = $coupon->get_usage_limit()-$counter;
                        echo "<span class='name-coupon'><b>Total usage for coupon </b><b>'</b><b>".$coupon->code."</b><b>'</b><b>: </b></span>";
                        echo "<span class='coupon-counter'>".($counter)."</span>";
                        echo "<span class='coupon-counter'> there are ".($remaining)." more left</span>";

            }
        }
    }
}
