好的，所以我正在尝试在我正在开发的应用程序中设置付款，我的对话框正在工作，它确认购买了该商品。我不知道它在这里之后做了什么，我已经阅读了一篇又一篇文章，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.
}
}
以上是部分支付回调
<? 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地方。
