在 Woocommerce 中，我试图找到一种方法，如果购物车中的重量超过 100 磅，则为整个客户的订单提供 10% 的折扣。我正在实现这一目标。对于下一步，我正在寻找一种通过functions.php 通过action/hook 以编程方式应用优惠券代码的方法。

看来我可以使用函数 woocommerce_ajax_apply_coupon 来执行此操作（http://docs.woothemes.com/wc-apidocs/function-woocommerce_ajax_apply_coupon.html），但我不确定如何使用它。

到目前为止，我已经修改了 cart.php 以获得购物车中所有产品的总重量，我已经创建了一个应用折扣的优惠券（如果手动输入），我已经向 functions.php 添加了一些代码来检查重量并向用户显示消息。

编辑：部分代码被删除，完整的代码包含在下面的解决方案中。

感谢弗雷尼的指导。这是在满足条件时成功应用折扣券并在不再满足时将其删除的工作最终结果：

/* Mod: 10% Discount for weight greater than 100 lbs 
Works with code added to child theme: woocommerce/cart/cart.php lines 13 - 14: which gets $total_weight of cart:
        global $total_weight;
        $total_weight = $woocommerce->cart->cart_contents_weight;
*/
add_action('woocommerce_before_cart_table', 'discount_when_weight_greater_than_100');
function discount_when_weight_greater_than_100( ) {
    global $woocommerce;
    global $total_weight;
    if( $total_weight > 100 ) {
        $coupon_code = '999';
        if (!$woocommerce->cart->add_discount( sanitize_text_field( $coupon_code ))) {
            $woocommerce->show_messages();
        }
        echo '<div class="woocommerce_message"><strong>Your order is over 100 lbs so a 10% Discount has been Applied!</strong> Your total order weight is <strong>' . $total_weight . '</strong> lbs.</div>';
    }
}

/* Mod: Remove 10% Discount for weight less than or equal to 100 lbs */
add_action('woocommerce_before_cart_table', 'remove_coupon_if_weight_100_or_less');
function remove_coupon_if_weight_100_or_less( ) {
    global $woocommerce;
    global $total_weight;
    if( $total_weight <= 100 ) {
        $coupon_code = '999';
        $woocommerce->cart->get_applied_coupons();
        if (!$woocommerce->cart->remove_coupons( sanitize_text_field( $coupon_code ))) {
            $woocommerce->show_messages();
        }
        $woocommerce->cart->calculate_totals();
    }
}

首先，创建一张折扣券（通过http://docs.woothemes.com/document/create-a-coupon-programatically/）：

$coupon_code = 'UNIQUECODE'; // Code - perhaps generate this from the user ID + the order ID
$amount = '10'; // Amount
$discount_type = 'percent'; // Type: fixed_cart, percent, fixed_product, percent_product

$coupon = array(
    'post_title' => $coupon_code,
    'post_content' => '',
    'post_status' => 'publish',
    'post_author' => 1,
    'post_type'     => 'shop_coupon'
);    

$new_coupon_id = wp_insert_post( $coupon );

// Add meta
update_post_meta( $new_coupon_id, 'discount_type', $discount_type );
update_post_meta( $new_coupon_id, 'coupon_amount', $amount );
update_post_meta( $new_coupon_id, 'individual_use', 'no' );
update_post_meta( $new_coupon_id, 'product_ids', '' );
update_post_meta( $new_coupon_id, 'exclude_product_ids', '' );
update_post_meta( $new_coupon_id, 'usage_limit', '1' );
update_post_meta( $new_coupon_id, 'expiry_date', '' );
update_post_meta( $new_coupon_id, 'apply_before_tax', 'yes' );
update_post_meta( $new_coupon_id, 'free_shipping', 'no' );

然后将该优惠券应用于您的订单：

if (!$woocommerce->cart->add_discount( sanitize_text_field( $coupon_code )))
    $woocommerce->show_messages();

最后一个函数返回一个 BOOL 值：如果折扣成功，则为 TRUE，如果由于各种原因中的任何一个而失败，则为 FALSE。

我使用了这个解决方案，但它包含 OP 编写的错误。如果用户跳过预览购物车并直接进入结帐表单，则不会应用优惠券。这是我的解决方案。

// Independence day 2013 coupon auto add
// Add coupon when user views cart before checkout (shipping calculation page).
add_action('woocommerce_before_cart_table', 'add_independence_day_2013_coupon_automatically');

// Add coupon when user views checkout page (would not be added otherwise, unless user views cart first).
add_action('woocommerce_before_checkout_form', 'add_independence_day_2013_coupon_automatically');

// Check if php function exists.  If it doesn't, create it.
if (!function_exists('add_independence_day_2013_coupon_automatically')) {

    function add_independence_day_2013_coupon_automatically() {

        global $woocommerce;
        $coupon_code = 'independencedaysale';
        $bc_coupon_start_date = '2013-06-30 17:00:00';
        $bc_coupon_end_date = '2013-07-08 06:59:59';

        // Only apply coupon between 12:00am on 7/1/2013 and 11:59pm on 7/7/2013 PST.
        if ((time() >= strtotime($bc_coupon_start_date)) &&
            (time() <= strtotime($bc_coupon_end_date))) {

            // If coupon has been already been added remove it.
            if ($woocommerce->cart->has_discount(sanitize_text_field($coupon_code))) {

                if (!$woocommerce->cart->remove_coupons(sanitize_text_field($coupon_code))) {

                    $woocommerce->show_messages();

                }

            }

            // Add coupon
            if (!$woocommerce->cart->add_discount(sanitize_text_field($coupon_code))) {

                $woocommerce->show_messages();

            } else {

                $woocommerce->clear_messages();
                $woocommerce->add_message('Independence day sale coupon (10%) automatically applied');
                $woocommerce->show_messages();

            }

            // Manually recalculate totals.  If you do not do this, a refresh is required before user will see updated totals when discount is removed.
            $woocommerce->cart->calculate_totals();

        } else {

            // Coupon is no longer valid, based on date.  Remove it.
            if ($woocommerce->cart->has_discount(sanitize_text_field($coupon_code))) {

                if ($woocommerce->cart->remove_coupons(sanitize_text_field($coupon_code))) {

                    $woocommerce->show_messages();

                }

                // Manually recalculate totals.  If you do not do this, a refresh is required before user will see updated totals when discount is removed.
                $woocommerce->cart->calculate_totals();

            }

        }

    }

}

自 Woocommerce 3 以来的2017 / 2019

一个挂钩函数中的以下紧凑代码将根据显示自定义消息的购物车总重量添加折扣（优惠券）。如果客户更改购物车项目，代码将检查购物车项目，如果购物车重量低于定义的重量，则删除折扣（优惠券）。

编码：

add_action('woocommerce_before_calculate_totals', 'discount_based_on_weight_threshold');
function discount_based_on_weight_threshold( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
        return;

    // Your settings
    $coupon_code      = 'onweight10'; // Coupon code
    $weight_threshold = 100; // Total weight threshold

    // Initializing variables
    $total_weight     = $cart->get_cart_contents_weight();
    $applied_coupons  = $cart->get_applied_coupons();
    $coupon_code      = sanitize_text_field( $coupon_code );

    // Applying coupon
    if( ! in_array($coupon_code, $applied_coupons) && $total_weight >= $weight_threshold ){
        $cart->add_discount( $coupon_code );
        wc_clear_notices();
        wc_add_notice( sprintf(
            __("Your order is over %s so a %s Discount has been Applied! Your total order weight is %s.", "woocommerce"),
            wc_format_weight( $weight_threshold ), '10%', '<strong>' . wc_format_weight( $total_weight ) . '</strong>'
        ), "notice");
    }
    // Removing coupon
    elseif( in_array($coupon_code, $applied_coupons) && $total_weight < $weight_threshold ){
        $cart->remove_coupon( $coupon_code );
    }
}

代码位于您的活动子主题（或活动主题）的 function.php 文件中。测试和工作。
