根据 WooCommerce 中的订单数量设置折扣

Question

在WooCommerce中，如何根据订单数量设置折扣？

例如我想根据客户订单应用折扣：

首单优惠 $50
二阶优惠$30
第三次订单折扣 10 美元？

我搜索了互联网，但没有找到任何可用的解决方案或插件。

谢谢。

这是一个挂接到 woocommerce_cart_calculate_fees 的自定义函数，它将根据客户订单数量向购物车添加自定义折扣，这样：

add_action('woocommerce_cart_calculate_fees' , 'discount_based_on_customer_orders', 10, 1);
function discount_based_on_customer_orders( $cart_object ){

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;  

    // Getting "completed" customer orders
    $customer_orders = get_posts( array(
        'numberposts' => -1,
        'meta_key'    => '_customer_user',
        'meta_value'  => get_current_user_id(),
        'post_type'   => 'shop_order', // WC orders post type
        'post_status' => 'wc-completed' // Only orders with status "completed"
    ) );

    // Orders count
    $customer_orders_count = count($customer_orders);

    // The cart total
    $cart_total = WC()->cart->get_total(); // or WC()->cart->get_total_ex_tax()

    // First customer order
    if( empty($customer_orders) || $customer_orders_count == 0 ){
        $discount_text = __('First Order Discount', 'woocommerce');
        $discount = -50;
    } 
    // 2nd orders discount
    elseif( $customer_orders_count == 1 ){
        $discount_text = __('2nd Order Discount', 'woocommerce');
        $discount = -30;            
    } 
    // 3rd orders discount
    elseif( $customer_orders_count == 2 ){
        $discount_text = __('3rd Order Discount', 'woocommerce');   
        $discount = -10;        
    }

    // Apply discount
    if( ! empty( $discount ) ){
        // Note: Last argument is related to applying the tax (false by default)
        $cart_object->add_fee( $discount_text, $discount, false);
    }
}

代码在您的活动子主题（或主题）的 function.php 文件或任何插件文件中。

此代码已经过测试并且有效。

The only problem can be if customer is not logged in.

You may add, at the beginning, in first condition ! is_user_logged_in() this way:
    if ( is_admin() && ! defined( 'DOING_AJAX' ) && ! is_user_logged_in() )
        return;
