i am trying to make a donation page using stripe with a custom amount. the code works perfect with fixed amount, but when i change it to variable amount it return 0, please help i tried many ways but nothing work. this is a snippet of the code

checkout.html

 <body>
    <section>

        <div class="panel">
          <h3>Donate Now</h3>
         <input type="number" id="amount" value="100"/>
        </div>
   

      <button type="button" id="checkout-button">Checkout</button>
    
    </section>
  </body>
    
  <script type="text/javascript" charset="utf-8">
    // Create an instance of the Stripe object with your publishable API key
    var stripe = Stripe("pk_test_51J2BvHLTS6YsumlzTSoJwjdzJpMt5zUhcBcJo16SQnmOs1EJKLwW5CThE2qud0xMDZFq5q1b6ezNc29Q7Hc2nQaa00uAjNryX3");
      
    var checkoutButton = document.getElementById("checkout-button");

    checkoutButton.addEventListener("click", function () {
      fetch("create-checkout-session.php", {
        method: "POST", 
        headers: { 'Content-Type': 'application/json',},
        body: JSON.stringify({amount: parseInt(parseInt(amount.value) * 100, 10),}),  
      
      })
        .then(function (response) {
          return response.json();
        })
        .then(function (session) {
          return stripe.redirectToCheckout({ sessionId: session.id });
        })
        .then(function (result) {
          
          if (result.error) {
            alert(result.error.message);
          }
        })
        .catch(function (error) {
          console.error("Error:", error);
        });
    });
  </script>
</html> 

this is the php code:

create-checkout-session.php

    <?php

include'stripe-php/init.php';

header('Content-Type: application/json; charset=UTF-8');

\Stripe\Stripe::setApiKey('sk_test_xxxxxxxxx');

$DOMAIN = 'http://localhost/hro';

$content = json_decode(file_get_contents('php://input'), true);
$amount = intval($content['amount']);

var_dump (file_get_contents('php://input'));

 $session = \Stripe\Checkout\Session::create([
          'payment_method_types' => ['card'],
          'line_items' => [[
            'price_data' => [
              'currency' => 'usd',
              'unit_amount' => $amount,
              'product_data' => [
                'name' => 'Your Donation Amount',
              ],
            ],
            'quantity' => 1,
          ]],
          'mode' => 'payment',
          'success_url' => $DOMAIN . '/success.html',
          'cancel_url' => $DOMAIN . '/cancel.html',
        ]);

echo json_encode(['id' => $session->id]);

解决方案


您的 JS 代码看起来不错,但是:请检查服务器端的金额类型。因为这将是一个字符串。然后你必须把它转换成一个int。 intval($amount)
