Facebook付款對話不起作用

Question

以下是錯誤代碼： 「您使用的應用程序未響應，請稍後再試。」

回調設置爲php文件（通過https）。我不知道爲什麼它不起作用。

這裏的JS（綁定到VAR博士）：

dr.buyCoins = function(){ 
    var obj = { 
     method: 'pay', 
     order_info: order_info, 
     action: 'buy_item', 
     dev_purchase_params: {'oscif': true} 
    }; 

    FB.ui(obj, dr.coinCheck); 
} 

dr.coinCheck = function(d){ 
    if (d['order_id']) { 
    return true; 
    } else { 
    return false; 
    } 
} 

和這裏的PHP：

<?php
