问题描述

我希望为特定的可变产品设置特定折扣,如果客户购买一种产品,他们会以 50% 的折扣获得另一种(相同的)(买一个 50% 的折扣).我试过很多折扣插件,我发现最接近的是:

I wish to set up a specific discount on a particular variable products, if customer buys one product they get the another(same) on 50% discount(Buy one get another for 50% off). I've tried many discount plugins buy the closest that I have found are:

  • WooCommerce 的定价交易

  • Pricing Deals for WooCommerce

WooCommerce 所有折扣精简版

WooCommerce All Discounts Lite

通过使用这些插件,我可以为每个产品设置小计折扣或折扣,但不完全是我想要的(买 1 送 1).还有其他专业插件我不想去.

By using these plugins I was able to setup discount on subtotal or discount on a each product but not exactly what I am looking for(Buy 1 get 1 off). There are other pro plugins I don't want to go for it.

不买插件可以实现吗?

谢谢

推荐答案

更新 (与你的评论有关)

此版本将在此定义的可变产品的购物车中的所有产品变体上全局运行:

This version will work globally on all product variations in the cart for this defined variable product:

add_action('woocommerce_cart_calculate_fees', 'add_custom_discount_2nd_at_50', 10, 1 );
function add_custom_discount_2nd_at_50( $wc_cart ){
    if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;
    $discount = 0;
    $items_prices = array();

    // Set HERE your targeted variable product ID
    $targeted_product_id = 40;

    foreach ( $wc_cart->get_cart() as $key => $cart_item ) {
        if( $cart_item['product_id'] == $targeted_product_id ){
            $qty = intval( $cart_item['quantity'] );
            for( $i = 0; $i < $qty; $i++ )
                $items_prices[] = floatval( $cart_item['data']->get_price());
        }
    }
    $count_items_prices = count($items_prices);
    if( $count_items_prices > 1 ) foreach( $items_prices as $key => $price )
        if( $key % 2 == 1 ) $discount -= number_format($price / 2, 2 );

    if( $discount != 0 ){
        // Displaying a custom notice (optional)
        wc_clear_notices();
        wc_add_notice( __("You get 50% of discount on the 2nd item"), 'notice');

        // The discount
        $wc_cart->add_fee( 'Discount 2nd at 50%', $discount, true  );
        # Note: Last argument in add_fee() method is related to applying the tax or not to the discount (true or false)
    }
}

代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

此代码已在 Woocommerce 3+ 上进行测试并有效.

原答案:

有多种方法可以为特定可变产品 ID 的第二件商品添加 50% 的自定义折扣.下面我使用 add_fee() 方法和一个负值 (所以它增加了折扣).
可选择显示自定义通知:

There is many ways to do add a custom discount of 50% on the 2nd item for a specific variable product ID. Below I am using add_fee() method with a negative value (so it adds a discount).
Optionally it will display a custom notice:

add_action('woocommerce_cart_calculate_fees', 'add_custom_discount_2nd_at_50', 10, 1 );
function add_custom_discount_2nd_at_50( $wc_cart ){
    if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;
    $discount = 0;

    // Set HERE your targeted variable product ID
    $targeted_product_id = 40;

    foreach ( $wc_cart->get_cart() as $key => $cart_item ) {
        if( $cart_item['product_id'] == $targeted_product_id ){
            $price = $cart_item['data']->get_price();
            $quantity = intval( $cart_item['quantity'] );
            for( $i = 1, $j = 0; $i <= $quantity; $i++ ){
                if( $i % 2 == 0 &&  $quantity > 1 ) $j++;
            }
            if( $quantity > 1 ) number_format($discount -= $price * $j / 2, 2 );
        }
    }
    if( $discount != 0 ){
        // Displaying a custom notice (optional)
        wc_clear_notices();
        wc_add_notice( __("You get 50% of discount on the 2nd item"), 'notice');
        
        $wc_cart->add_fee( 'Discount 2nd at 50%', $discount, true  );
        # Note: Last argument in add_fee() method is related to applying the tax or not to the discount (true or false)
    }
}
