STRIPE - 在charge.php上調用時動態設置金額返回null

Question

我試圖讓用戶通過Stripe動態設置他們的捐贈值。我已經能夠使用StripeAmount變量爲'amount'賦值，但是當我嘗試在我的charge.php文件中調用該變量時，該變量返回null。我有搜索谷歌無盡的解決方案，但沒有工作。我是一個相對的新手。

=表單代碼=

 <form id="target_form" action="charge.php" method="POST"> 

     <script src="https://checkout.stripe.com/checkout.js"></script> 

     <button class="stripe_button_style" id="myStripeButton">Give By Card</button>   

       <script> 
        var handler = StripeCheckout.configure({ 
         key: "pk_test_xxxxxxxxxxxxxxxx", 
         image: "includes/images/stripe_logo.png", 
         token: function(token, args){ 
          var form = $('#target_form'); 
          form.append($('<input type="hidden" name="stripeToken" />').val(token.id)); 

          form.get(0).submit(); 
          } 
        }); 

        document.getElementById('myStripeButton').addEventListener('click', function(e) { 

         var StripeAmount = $("#donation_amount").val() *100; 

         handler.open({ 
          name: "company name", 
          description: "donation", 
          panelLabel: "Give:", 
          allowRememberMe: true, 
          amount: StripeAmount, 
          zipCode: true, 
          shippingAddress: true, 
          billingAddress: true 
         }); 
          e.preventDefault(); 
         }); 

         $(window).on('popstate', function() { 
         handler.close(); 
        }); 
       </script> 

      </form> 

= Charge.php代碼=

<?php require_once('includes/stripe/init.php'); 
$stripe = array(
    "secret_key"  => "sk_test_xxxxxxxxxxxxxxxxxxxxxxxx", 
    "publishable_key" => "pk_test_xxxxxxxxxxxxxxxxxxxxxxxx" 
); 
    \Stripe\Stripe::setApiKey($stripe['secret_key']); 
    $token = $_POST['stripeToken']; 
    $email = $_POST['stripeEmail']; 
    try { 
    $customer = \Stripe\Customer::create(array(
    'email' => $_POST['stripeEmail'], 
    'source' => $token)); 
$charge = \Stripe\Charge::create(array(
    'amount' => $amount, 
    'customer' => $customer->id, 
    'currency' => "usd", 
    'description' => $email)); 
    echo 'Thank you for your donation. We will send you a receipt by email for your tax records within 48hours'; 

    var_dump($charge); 
}catch(\Stripe\Error\Card $e){ 

echo $e->getMessage(); 

} 

Answer 1

在您的服務器端代碼，$amount永遠不會初始化。

此外，請注意傳遞到Checkout的金額和貨幣用於顯示目的。結帳不會將金額和貨幣發送到服務器。

你需要做這樣的事情：

1. 更新您的客戶端代碼量發送到服務器：

   token: function(token, args) { 
       var form = $('#target_form'); 
       form.append($('<input type="hidden" name="amount" />').val($("#donation_amount").val() * 100;)); 
       form.append($('<input type="hidden" name="stripeToken" />').val(token.id)); 
       form.get(0).submit(); 
   } 
   

2. 檢索您的服務器 - 量端代碼：

   $amount = $_POST['amount'];
