在 WooCommerce 感谢页面中显示优惠券使用次数和限制 [英] Display coupon usage count and limit in WooCommerce thank you page

问题描述

我想在 WooCommerce 感谢页面上显示优惠券的剩余数量

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

例如:您使用了测试优惠券3次，还剩10次.

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

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>";

            }
        }
    }
}

但我有两个问题:

1.此代码只显示使用次数，不显示剩余次数.

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

2.在感谢页面用woocommerce_thankyou替换woocommerce_after_cart_table不会执行代码.

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

推荐答案

• 在感谢页面上使用订单对象而不是购物车对象.所以我们将使用那个对象来代替

  • Instead of using the cart object, the order object is used on the thankyou page. So we're going to use that object instead

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

    You can use get_usage_limit_per_user() to get coupon usage limit per customer (for a single customer)

    OR 使用 get_usage_limit() 获取优惠券使用限制.

    OR use get_usage_limit() to get coupon usage limit.

    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 );
