Question

好的，所以我正在尝试在我正在开发的应用中设置付款，我让对话框正常工作并确认购买该商品。我不知道它在这之后做了什么tbh，我读过文章后的文章，但没有快乐。我需要有关如何在购买时更新mysql数据库的信息。我知道这个问题很模糊，但任何指导都将不胜感激！

我到目前为止的代码如下。

if ($request_type == 'payments_get_items') {
  // Get order info from Pay Dialog's order_info.
  // Assumes order_info is a JSON encoded string.
  $order_info = json_decode($request['credits']['order_info'], true);

  // Get item id.
  $item_id = $order_info['item_id'];

  // Simulutates item lookup based on Pay Dialog's order_info.
  if ($item_id == '10Kremeggs') {
    $item = array(
      'title' => '10 Kremeggs',
      'description' => 'Spend Kremeggs in Alien Abduction.',
      // Price must be denominated in credits.
      'price' => 5,
      'image_url' => 'https://afternoon-snow-5267.herokuapp.com/images/bung.png',
      'product_url' => 'https://afternoon-snow-5267.herokuapp.com/Purchase/10xKremeggs.php'
    );

    // Construct response.
    $response = array(
                  'content' => array(
                                 0 => $item,
                               ),
                  'method' => $request_type,
                );
    // Response must be JSON encoded.
    $response = json_encode($response);
  }

} else if ($request_type == "payments_status_update") {
  // Get order details.
  $order_details = json_decode($request['credits']['order_details'], true);

  // Determine if this is an earned currency order.
  $item_data = json_decode($order_details['items'][0]['data'], true);
  $earned_currency_order = (isset($item_data['modified'])) ?
                             $item_data['modified'] : null;

  // Get order status.
  $current_order_status = $order_details['status'];

  if ($current_order_status == 'placed') {
    // Fulfill order based on $order_details unless...

    if ($earned_currency_order) {
      // Fulfill order based on the information below...
      // URL to the application's currency webpage.
      $product = $earned_currency_order['product'];
      // Title of the application currency webpage.
      $product_title = $earned_currency_order['product_title'];
      // Amount of application currency to deposit.
      $product_amount = $earned_currency_order['product_amount'];
      // If the order is settled, the developer will receive this
      // amount of credits as payment.
      $credits_amount = $earned_currency_order['credits_amount'];
    }

    $next_order_status = 'settled';

    // Construct response.
    $response = array(
                  'content' => array(
                                 'status' => $next_order_status,
                                 'order_id' => $order_details['order_id'],
                               ),
                  'method' => $request_type,
                );
    // Response must be JSON encoded.
    $response = json_encode($response);

  } else if ($current_order_status == 'disputed') {
    // 1. Track disputed item orders.
    // 2. Investigate user's dispute and resolve by settling or refunding the order.
    // 3. Update the order status asychronously using Graph API.

  } else if ($current_order_status == 'refunded') {
    // Track refunded item orders initiated by Facebook. No need to respond.

  } else {
    // Track other order statuses.

  }
}

以上是付款回调的一部分

<? mysql_query("UPDATE users SET Kremeggs = Kremeggs+10 WHERE Facebook_id = '$PurchaseUpdate'");
header ("Location: http://apps.facebook.com/alien_abduction/purchaseComplete.php");
?>
</body>
</html>

以上是我需要付款的事情。

Answer 1

听起来你正试图在一个文件（第二个代码示例）中同时处理该过程的两个非常独立的部分。您发布的第一个代码示例（看起来像他们的示例代码，这很好）是授予用户的适当位置 - 您的mysql查询属于从第43行（if ($current_order_status == 'placed') {）开始的块内。我将把这些细节留给你解决。

您要执行的操作的后半部分（将用户重定向到确认页面）不属于该回调，而是在带有付款对话框的页面上。如果你在那里使用示例代码，它也属于js_callback函数 - 尝试window.location.href='purchase_complete.php'（确保这只发生在成功的订单上，ofc）。

希望能让你指出正确的方向！

Answer 2

else if ($request_type == "payments_status_update") {mysql_query("update users_table set payment_column='isok' where kulid like 'getFacebookUserId'");}

开发人员响应 - 付款回拨。 PHP - 让我发疯
