Question

我的woocommerce产品实际上是巡航探险（两种产品=两种探险类型）。对于每种产品，变化包括巡航发生的周数（=日期）。所以我有20个不同星期的利古里亚海上探险队和其他20周的希腊远征队。幸运的是，我只有2个这样的产品可以处理（非常简单的情况）

顾客通常选择一周的探险。但是，如果客户决定申请＆gt;，我需要在第二周（或第三周）申请10％的折扣。 1周。因此，第一周支付全价，但第二周和（如果有）第三周将打折10％。

我已经推出了一个功能，可以在两周的情况下应用折扣。

function cart_discount() {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    global $woocommerce; $cat_count = 0; 

    $cart = WC()->cart->get_cart();

    foreach($cart as $cart_item_key => $values) { 
        $product_id = $values['product_id']; // product ID (= cruise type)
        $variation_id = $values['variation_id']; // variation (=week)
        $cart_lines_total = $values["line_total"]; //variation total price
        $cart_lines_quantity = $values["quantity"];// variation quantity

            //$product = 1394 = Expedition Ligurian eng
            //$product = 1389 = Expedition Greece eng
            //$product = 13888 = Expedition Ligurian ita
            //$product = 13910 = Expedition Greece ita

        //I hereby add a condition as we do have the same cruises with students prices which are not eligible to this discount (and are stored with different product_id)
        if($product_id == '1394' || $product_id == '1389' || $product_id == '13888' || $product_id == '13910')
        {
            //put in a new array only the terms I need for the calculation later
            $cart_array []= array( $product_id , $variation_id, $cart_lines_quantity, $cart_lines_total);
        }
    }


        // discount percent is 10%
        $percent = -0.10;

    if ($cart_array[0][0] == $cart_array[1][0]) //if in the cart the same product is present two times
    {
        $discount = $percent * $cart_array[1][2] * $cart_array[1][3];
        $discount_text = __( 'Quantity discount', 'woocommerce' );
        WC()->cart->add_fee( $discount_text, $discount, false );
    }


}
add_action( 'woocommerce_cart_calculate_fees','cart_discount' );

如前所述，此代码有许多限制，因为它没有考虑到某些情况，例如：

1）只有在购物车中只有同一产品的两种变体才会处理：如果客户决定购买x周，我应该能够检查同一产品是否存在＆gt; 2种变化;

2）它没有考虑到两种产品有两种变化的可能性（即，一个人在利古里亚海购买两周，在希腊购买两周）

如果有人可以帮我改进我写的代码，我会非常高兴!!

Answer 1

为了确保我做对了，如果客户购买同一产品的1种以上变体，您希望申请折扣。正确的吗？

Answer 2

这是我写的最终代码（它有效，我已经测试过了）

function cart_discount() {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;
    global $woocommerce; 


            $cart = WC()->cart->get_cart();

            $has_coupons = count(WC()->cart->applied_coupons)>0?true:false;

            if(!$has_coupons) //verifies that other discounts are not added
            {
                  foreach($cart as $cart_item_key => $values) { 
                      $product_id = $values['product_id']; // product ID
                      $variation_id = $values['variation_id']; // product quantity
                      $cart_lines_total = $values["line_total"];
                      $cart_lines_quantity = $values["quantity"];

                          //products for which this kind of discount must be applicable:
                          //$product_id = 1394 = Spedizioni CSR eng
                          //$product_id = 1389 = Spedizioni IDP eng
                          //$product_id = 13888 = Spedizioni CSR ita
                          //$product_id = 13910 = Spedizioni IDP ita

                      if($product_id == '1394' || $product_id == '1389' || $product_id == '13888' || $product_id == '13910')
                      {
                          $cart_array []= array( $product_id , $variation_id, $cart_lines_quantity, $cart_lines_total);
                      }
                  }

                      $conteggio = count($cart_array); //conta il numero di prodotti nel carrello 
                      // percent is 10%
                      $percent = -0.10;

                  if ($conteggio < 3 && $cart_array[0][0] == $cart_array[1][0])
                  { 
                      $discount = $percent *  $cart_array[1][3];
                      $discount_text = __( '10% discount on subsequent week(s)', 'woocommerce' );
                      WC()->cart->add_fee( $discount_text, $discount, false );
                  }
                  if ($conteggio < 4 && $cart_array[0][0] == $cart_array[1][0] && $cart_array[0][0] == $cart_array[2][0])
                  {
                      $discount = ($percent * $cart_array[1][3]) + ($percent * $cart_array[2][3]);
                      $discount_text = __( '10% discount on subsequent week(s)', 'woocommerce' );
                      WC()->cart->add_fee( $discount_text, $discount, false );
                  }
                  if ($conteggio < 5 && $cart_array[0][0] == $cart_array[1][0] && $cart_array[0][0] == $cart_array[2][0] && $cart_array[0][0] == $cart_array[3][0])
                  {
                      $discount = ($percent * $cart_array[1][3]) + ($percent * $cart_array[2][3]) + ($percent * $cart_array[3][3]);
                      $discount_text = __( '10% discount on subsequent week(s)', 'woocommerce' );
                      WC()->cart->add_fee( $discount_text, $discount, false );
                  }
            } else return;


}
add_action( 'woocommerce_cart_calculate_fees','cart_discount' );

如你所见，我必须指定对这种特殊折扣感兴趣的产品的product_id，这对我来说没问题，但如果我们可以将它设置为类别会更好（我没有＆＃39;有时间发展这种情况）其次，我不喜欢的部分是以下

if ($conteggio < 3 && $cart_array[0][0] == $cart_array[1][0])

以及以下所有条件：我正在寻找可以通过$cart_array的函数，并找到我在每个if（）条件下手动设置的关系。

由于

Woocommerce条件部分购物车折扣与同一产品同时出现＆gt; 1变体
