自動爲特定產品ID和數量自動應用優惠券

Question

我試圖根據產品ID和數量條件自動在我的WooCommerce商店中應用優惠券。我的最終目標是在將兩（2）個所需產品添加到購物車時自動應用特定優惠券，並在購買三（3）個所需產品時自動應用其他優惠券。單一數量的產品應該沒有折扣。 以下是代碼，現在該功能修正版本：

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(); 
     } 
    } 
    } 
}

的Theres很多代碼中的錯誤的，這是一個有點過時的太... 我已經在你的函數的rewrite everithing和把它鉤在另一個鉤子上。

這是你重新編號：

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'); 
       } 
      } 
     } 
    } 
} 

此代碼放在你的活躍兒童主題（或主題）的function.php文件或也以任何插件文件。

這應該工作，不會讓你的網站崩潰，但我沒有真正測試它，因爲這是非常特殊的。
