根據訂單總額折扣

當我的設定數量滿足時，下面的代碼變爲激活狀態。根據訂單總額折扣

但是如果我的設定數量爲三摺合格折扣，那麼如果有任何客戶購買四件產品，它仍然只給三件產品打折。

它等待另外三個給予折扣。但是，如果我設定的最小數量符合要求，那麼它會根據我設定的百分比給予總訂單折扣。

  1. 我不知道編碼。任何人都可以幫助解決它與編碼？

  2. 我是新來的stackoverflow。如果我的解釋能力不對，那麼我請你道歉。

這是代碼。

這是預期的行爲 - 如果你買了3個款產品，你得到一個％年齡過最便宜的，所以當然如果你想要的折扣你將有兩款產品購買6.

但是你想要它，所以如果你購買3個或更多產品，你會得到每個額外產品的折扣？ （例如，如果你購買4，你會得到2折扣，如果你購買5，折扣適用於3等？）

如果你不熟悉編碼，我不會真的建議要與此搞亂（或絕對保留備份你做之前），但我會做的修改是在catalog/model/total/total_discount.php您發佈的最後一個文件：

更改線路

$items_count = floor($count/(int)$this->config->get('total_discount_count'));

到

if ($count > (int)$this->config->get('total_discount_count')) { 
    $items_count = $count - (int)$this->config->get('total_discount_count'); 
} else { 
    $items_count = 0; 
}

這樣做的結果是，如果您說3種產品爲折扣計數，則折扣適用的產品數將爲購物車中產品的數量減3。第四，第五，第六等，將已申請貼現）

編輯

只是重讀你的問題，我現在明白了，你想，如果應用到整個訂單的折扣至少X產品進行排序？

如果是，則改變上面

if ($count >= (int)$this->config->get('total_discount_count')) { 
    $items_count = $count; 
} else { 
    $items_count = 0; 
}

如果達到期望的效果的同一條線上。它不會影響郵資或任何其他額外費用。
