基于特定商品变化的购物车商品折扣

是一个变量积 基于某些产品属性的多种变体。

对你来说, 折扣可采用两种不同的方式

但首先需要定义相关的产品属性 这是涉及到“可重复使用的湿”数量包装和相关的术语 姓名 代码中“5包”的值。

如果没有以正确的方式完成这些任务,代码将无法工作。

1) :

这里我们定了一个折扣单价 9 ( 18 / 2 = 9 ) 当购物车中有2个或更多相关项目时。

add_action( 'woocommerce_before_calculate_totals', 'conditionally_set_discounted_price', 30, 1 );
function conditionally_set_discounted_price( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

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

    // HERE your product attribute slug for "Reusable wet" (without "pa_")
    $product_attr = 'reusable-wet';
    $product_attr = 'color';

    // HERE set the corresponding (value) term NAME for "5 Reusable wet"
    $term_slug = '5 reusable wet';
    $term_slug = 'Black';

    // HERE set the discounted price for each cart item with "5 Reusable wet" when they are 2 or more
    $discounted_price = 9; // (18 / 2 = 9)

    $five_rw_count = 0; // Initializing variable

    // 1st Loop: count cart items with "5 Reusable wet"
    foreach ( $cart->get_cart() as $cart_item ){
        if( $cart_item['data']->get_attribute( $product_attr ) == $term_slug ){
            $five_rw_count += $cart_item['quantity'];
        }
    }

    // Continue if there is at least 2 units of "5 Reusable wet"
    if( $five_rw_count < 2 ) return; // Exit

    // 2nd Loop: set the discounted price for cart items with "5 Reusable wet"
    foreach ( $cart->get_cart() as $cart_item ){
        if( $cart_item['data']->get_attribute( $product_attr ) == $term_slug ){
            $cart_item['data']->set_price($discounted_price); // Set the discounted price
        }
    }
}

代码进入函数.php活动子主题(或活动主题)的文件。测试和工作

2) 优惠券方式 (由于许多逻辑原因不太方便) :

完成后,您将在以下代码中设置优惠券名称(小写):

add_action( 'woocommerce_before_calculate_totals', 'conditionally_auto_add_coupon', 30, 1 );
function conditionally_auto_add_coupon( $cart ) {
    if ( is_admin() && !defined('DOING_AJAX') ) return; // Exit

    // HERE your product attribute slug for "Reusable wet" (without "pa_")
    $product_attr = 'reusable-wet';

    // HERE set the corresponding (value) term NAME for "5 Reusable wet"
    $term_slug = '5 reusable wet';

    // HERE set the coupon code (in lowercase)
    $coupon_code = 'multiplefive';

    $five_rw_count = 0; // Initializing variable

    // 1st Loop: count cart items with "5 Reusable wet"
    foreach ( $cart->get_cart() as $cart_item ){
        if( $cart_item['data']->get_attribute( $product_attr ) == $term_slug ){
            $five_rw_count++; // Increasing count
        }
    }

    // Apply the coupon if there is at least 2 units of "5 Reusable wet"
    if ( ! $cart->has_discount( $coupon_code ) && $five_rw_count >= 2 ) {
        $cart->add_discount( $coupon_code );  
    } 
    // Remove the coupon if there is at less than 2 units of "5 Reusable wet"
    elseif  ( $cart->has_discount( $coupon_code ) && $five_rw_count < 2 ) {
        $cart->remove_coupon( $coupon_code );
    }
}
