有条件地为特定产品ID和数量自动应用优惠券

我正在尝试根据产品ID和数量条件自动在我的WooCommerce商店中应用优惠券 . 我的最终目标是，当将所需产品的两（2）个添加到购物车时自动应用特定优惠券，并且每当将三（3）个所需产品添加到购物车时自动应用另一个优惠券到应用 . 单个数量的产品应该没有折扣 . The following is the CORRECTED version of the code, which now works ：

add_action( 'woocommerce_before_cart', 'conditional_auto_add_coupons' );
function conditional_auto_add_coupons() {

if ( !WC()->cart->is_empty() ){

    // Define HERE your Targeted Product ID and coupons codes
    $target_pid = 103;
    $coupon1 = 'soccer-sibling-2';
    $coupon2 = 'soccer-sibling-3';

    // First cart loop: Counting number of subactegory items in cart
    foreach ( WC()->cart->get_cart() as $cart_item ){
        if( $target_pid == $cart_item['data']->id ){
            // Removes any coupons in the cart already
            WC()->cart->remove_coupons();
            if( 2 == WC()->cart->get_cart_contents_count() && !WC()->cart->has_discount( $coupon1 ) ){
                WC()->cart->remove_coupons();
                WC()->cart->add_discount( $coupon1 );
                wc_add_notice( __( 'The multiple sibling discount has been applied.', 'theme_domain' ), 'success' );
            } elseif( 3 == WC()->cart->get_cart_contents_count() && !WC()->cart->has_discount( $coupon2 ) ){
               WC()->cart->remove_coupons();
                WC()->cart->add_discount( $coupon2 );
                wc_add_notice( __( 'The multiple sibling discount has been applied.', 'theme_domain' ), 'success' );
            }
            // Recalculates Cart Totals to show correct price
            WC()->cart->calculate_totals();
        }
     }
  }
}

    你的代码中有很多错误，它也有点过时了...我已经在你的函数中重写了一个并且把它挂在另一个钩子里 .

    这是您重新访问的代码：

    add_action( 'woocommerce_before_cart', 'conditional_auto_add_coupons' );
function conditional_auto_add_coupons() {

    if ( !WC()->cart->is_empty() ){

        // Define HERE your Targeted Product ID and coupons codes
        $target_pid = 103;
        $coupon1 = 'soccer-sibling-2';
        $coupon2 = 'soccer-sibling-3';

        // First cart loop: Counting number of subactegory items in cart
        foreach ( WC()->cart->get_cart() as $cart_item ){
            if( $target_pid == $cart_item['data']->id ){
                if( 2 == WC()->cart->get_cart_contents_count() && !WC()->cart->has_discount( $coupon1 ) ){
                    WC()->cart->add_discount( $coupon1 );
                    wc_add_notice( __( 'A quantity discount of <strong>5%</strong> has been added.', 'theme_domain' ), 'success' );
                } elseif( 3 == WC()->cart->get_cart_contents_count() && !WC()->cart->has_discount( $coupon2 ) ){
                    WC()->cart->add_discount( $coupon2 );
                    wc_add_notice( __( 'A quantity discount of <strong>10%</strong> has been added.', 'theme_domain' ), 'success' );
                }
            }
        }
    }
}

    此代码位于活动子主题（或主题）的function.php文件中，或者也可以放在任何插件文件中 .

    这应该工作，不会让你的网站崩溃，但我没有真正测试它，因为这是非常特殊的 .
