在 WooCommerce 感谢页面中显示优惠券使用次数和限制

Display coupon usage count and limit in WooCommerce thank you page

我想在 WooCommerce 谢谢页面上显示优惠券的剩余数量

例如:您使用了测试优惠券3次,还有10张.

这是我的代码:

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>";

            }
        }
    }
}

但是我有两个问题:

1.With此代码,只显示使用次数不显示剩余次数

2.Replacing woocommerce_after_cart_table with woocommerce_thankyou 在感谢页面上不执行代码。

  • 感谢页面上使用了订单对象,而不是购物车对象。所以我们要改用那个对象

  • 您可以使用get_usage_limit_per_user()获取每个客户的优惠券使用限制(针对单个客户)

  • 使用get_usage_limit()获取优惠券使用限制。

所以你得到:

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 );
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>";

            }
        }
    }
}
