布倫特裏交易中的未定義Post變量

我正在爲swift快速設置我的OSX桌面應用程序的付款處理。由於沒有用於OSX的SDK，因此我正在通過Braintree的PHP SDK使用Web視圖。我想傳遞一些POST數據，以便產品的價格從我的應用程序動態傳遞，但似乎無法識別，並且根據PHP錯誤進行了定義。
我知道如何發送POST變量到一個PHP腳本並做了很多次，但我有一種感覺，我的swift代碼可能不正確。我的PHP錯誤是：「通知：未定義的變量：價格」布倫特裏交易中的未定義Post變量

if(isset($_POST["price"])){ 

$price = $_POST["price"]; 

} 

<?php $tr_data = Braintree_TransparentRedirect::transactionData(
       array('redirectUrl' => "http://" , 
       'transaction' => array('amount' => $price, 'type' => 'sale'))) ?>

而且貝寶認爲，本質上是一種網絡當用戶點擊一個按鈕時，視圖被激活。我不知道這是否與這件事有關？

什麼，當你添加'的var_dump（$ _ POST）'到你的PHP代碼會發生什麼？ – Maximus2012

我得到數組（0）{}。我不確定它爲什麼沒有通過。 – Eseye

很可能您的開關代碼不會將POST（或任何請求）發送到您的PHP代碼。您可以使用Firebug/Web Developer瀏覽器插件來跟蹤GET/POST請求，以查看數據是否從Swift流向PHP。 – Maximus2012

        $amount = $_POST['amount']; 
      } 

      $tr_data = Braintree_TransparentRedirect::transactionData(
