問題描述

如果用戶是第一次訂購，我需要在計算稅前對購物車小計應用折扣.但是，稅是在 WooCommerce 中按項目計算的，然后添加到小計中.因此，我需要在 WooCommerce 計算對購物車中的商品征稅之前將折扣應用于購物車中的商品.這樣，稅款是基于折扣價而不是原始價格.

這是我所擁有的:

function first_order_add_five_percent_discount($cart_object) {如果 ( is_user_logged_in() ) {//當前用戶ID$currentUser_id = get_current_user_id();//當前用戶的訂單數量$orderAmount = wc_get_customer_order_count( $currentUser_id );//如果用戶有0個訂單...如果 ($orderAmount == 0) {//對于購物車中的每個項目foreach ( $cart_object->get_cart() 作為 $item_values ) {//$item_id = $item_values['data']->id;//產品編號$item_qty = $item_values['數量'];//物品數量$original_price = $item_values['data']->price;//產品原價回聲 $original_price ."<br>";$totalPrice = $original_price * $item_qty;$discountedPrice = $totalPrice * .05;$newPrice = $original_price - $discountedPrice;回聲 $totalPrice ."<br>";回聲 $discountedPrice ."<br>";回聲 $newPrice ."<br>";$item_values['data']->set_price($newPrice);}} 別的 {//沒做什么}}}add_action('woocommerce_before_calculate_totals', 'first_order_add_five_percent_discount');

這反映了我需要的正確數字，但現在我需要將這些價格應用到購物車.現在購物車中的價格沒有變化.

如何將來自此函數計算的新價格應用到購物車?

更新:使用負費用不是最好的方法，Woocommerce也不推薦使用.

###請注意，稅費將始終適用.

  I need to apply a discount to the cart subtotal before tax is calculated if a user is ordering for the first time. However, tax is calculated per-item in WooCommerce and added to the subtotal afterwards. So I need to apply the discount to the items in the cart before WooCommerce calculates the tax on them. This way the tax is based off of the discounted prices rather than the original prices.

  Here is what I have:

  function first_order_add_five_percent_discount($cart_object) {
  
      if ( is_user_logged_in() ) {
          //current user id
          $currentUser_id = get_current_user_id();
          //amount of orders by current user
          $orderAmount = wc_get_customer_order_count( $currentUser_id ); 
  
          //if user has 0 orders...
          if ($orderAmount == 0) {
              //for each item in cart
              foreach ( $cart_object->get_cart() as $item_values ) {
  
                  //$item_id = $item_values['data']->id; // Product ID
                  $item_qty = $item_values['quantity']; // Item quantity
                  $original_price = $item_values['data']->price; // Product original price
                  echo $original_price . "<br>";
                  $totalPrice = $original_price * $item_qty;
                  $discountedPrice = $totalPrice * .05;
                  $newPrice = $original_price - $discountedPrice;
                  echo $totalPrice . "<br>";
                  echo $discountedPrice . "<br>";
                  echo $newPrice . "<br>";
                  $item_values['data']->set_price($newPrice);
  
              }
  
          } else {
              //do nothing
          }
      }
  }
  
  add_action( 'woocommerce_before_calculate_totals', 'first_order_add_five_percent_discount' );
  

  This echos out the right numbers I need, but now I need to apply those prices to the cart. Right now the prices in the cart do not change.

  How can I apply the new prices from this function's calculations to the cart?

  解決方案

  UPDATE: Using a negative fee is not the best way and not recommended by Woocommerce.

  ###Note that the taxes will be always applied.
  

  Try instead:
  

  • Cart item quantity progressive percentage discount in Woocommerce 3
    

  • Cart item discount based on quantity in Woocommerce 3
    
  • Apply automatically a coupon based on specific cart items count in Woocommerce

  There is a much more simpler way, is to use a negative fee, so a discount. It use the WC_Cart method add_fee() where you can disable tax:

  add_action( 'woocommerce_cart_calculate_fees','new_customers_discount', 10, 1 );
  function new_customers_discount( $wc_cart ) {
      if ( is_admin() && ! defined('DOING_AJAX') ) return; // We exit
  
      // Only for logged in users
      if ( ! is_user_logged_in() ) return; // We exit
      
      // Only for new customers without orders
      if ( wc_get_customer_order_count( get_current_user_id() ) != 0 ) return;  // We exit
      
      // discount percentage
      $percent = 5;
  
      // Calculation
      $discount = $wc_cart->cart_contents_total * $percent / 100;
  
      $wc_cart->add_fee( __( 'Discount', 'woocommerce')." ($percent%)", -$discount );
  }
  

  Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

  Tested and working. you will get something like that:

  As you can see the discount is made on the cart content total excl. Tax
