带进度条的 Paypal 捐款跟踪

Question

我正在为非营利组织设计和构建一个网站。他们想要一个 PayPal 捐赠按钮，我希望能够展示他们迄今为止筹集了多少资金。

我对 PayPal API 还不够熟悉，甚至无法接近。因此，我需要知道的是如何获取作为整数值的捐赠总额，以便我可以将其除以所需的金额并获得百分比。

有人最熟悉如何做到这一点吗？

Answer 1

PayPal 为此提供了一个“实验室”（测试版）小部件。看看https://giving.paypallabs.com/authenticate/review

Answer 2

从未使用过 paypal API，但他们有代码示例：

Paypal 代码示例

这是他们的 getBalance 代码示例：

require_once 'PayPal.php';
require_once 'PayPal/Profile/Handler/Array.php';
require_once 'PayPal/Profile/API.php';
require_once 'PayPal/Type/GetBalanceRequestType.php';
require_once 'PayPal/Type/GetBalanceResponseType.php';

$environment = 'sandbox';   // or 'beta-sandbox' or 'live'

//--------------------------------------------------
// PROFILE
//--------------------------------------------------
/**
 *                    W A R N I N G
 * Do not embed plaintext credentials in your application code.
 * Doing so is insecure and against best practices.

 * Your API credentials must be handled securely. Please consider
 * encrypting them for use in any production environment, and ensure
 * hat only authorized individuals may view or modify them.

$handler = & ProfileHandler_Array::getInstance(array(
            'username' => 'my_api_username',
            'certificateFile' => null,
            'subject' => null,
            'environment' => $environment));

$pid = ProfileHandler::generateID();

$profile = & new APIProfile($pid, $handler);

$profile->setAPIUsername('my_api_username');
$profile->setAPIPassword('my_api_password');
$profile->setSignature('my_api_signature');
$profile->setCertificateFile('my_cert_file_path');
$profile->setEnvironment($environment);
//--------------------------------------------------

$balance_request =& PayPal::getType('GetBalanceRequestType');
$balance_request->setVersion("51.0");

$caller =& PayPal::getCallerServices($profile);

// Execute SOAP request
$response = $caller->GetBalance($get_balance_request);

switch($response->getAck()) {
    case 'Success':
    case 'SuccessWithWarning':
        // Extract the GetBalance response parameters
        $balance = $response->getBalance();
        $balance_amt = $balance->_value;
        $balance_currency_id = $balance->getattr('currencyID');

        $balance_time_stamp = $response->getBalanceTimeStamp();

        $balance_holdings = $response->getBalanceHoldings();
        $balance_holdings_amt = $balance_holdings->_value;
        $balance_holdings_currency_id = $balance_holdings->getattr('currencyID');

        exit('GetBalance Completed Successfully: ' . print_r($response, true));

    default:
        exit('GetBalance failed: ' . print_r($response, true));
}
