WooCommerce：自定義價格由用戶在購物車沒有清點

Question

我們使用下面的腳本允許用戶輸入自定義價格這個頁面上他們的禮品卡購買設置：http://oceanapoke.staging.wpengine.com/pages/gift-card/

的問題是，自定義在最近的WooCommerce 3.0.8更新中，價格不再是完全正確的。

故障排除這是我的舵手之外的方式。有沒有人可以指引我走向正確的方向？

因爲在新版本替換該行$value['data']->price = $value["variation"]["Price"];這個 $value['data']->set_price($value["variation"]["Price"]);我們只得到一個對象通過該對象的產品。我們可以調用set_price()函數來設置當前價格。
