php 在Woocommerce中以编程方式应用优惠券

在Woocommerce我试图找到一种方法来申请10%的折扣，以整个客户的订单，如果在购物车的重量超过100磅.我离实现这一目标已经有一半了。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来完成这个（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来获取购物车中所有产品的总重量，我已经创建了一个优惠券，适用于折扣（如果手动输入），我已经添加了一些代码到functions.php来检查重量并向用户显示消息。
编辑：删除了部分代码，完成的代码包含在下面的解决方案中。
谢谢你的指导，Freney。以下是工作结束的结果，当满足条件时成功应用折扣券，当不再满足时也会删除它：

/* 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 ))) {

首先，创建一个折扣券（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();

型
最后一个函数返回一个BOOL值：如果折扣成功，则返回TRUE;如果由于各种原因中的任何一种而失败，则返回FALSE。

我使用了这个解决方案，但它包含一个错误，因为OP写了它。如果用户跳过预览购物车并直接进入结账表单，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();

            }

    }

以下紧凑的代码在一个挂钩函数将添加一个折扣（优惠券）的基础上购物车总重量显示自定义消息。如果客户改变购物车项目的代码将检查购物车项目删除折扣（优惠券），如果购物车重量是在定义的重量。
代码：

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->apply_coupon( $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 );
    }
}

代码放在活动子主题（或活动主题）的functions.php文件中。经过测试，工作正常。
