Braintree 托管字段集成答案

【问题标题】：Braintree Hosted Fields IntegrationBraintree 托管字段集成

【问题描述】：

我正在尝试在我的注册表单上设置 Braintree 托管字段。但是这些领域之间存在巨大的差距，而且看起来并不正确。我尝试过使用 Braintree 文档和指南，但它们非常模糊。

我认为自己是一名中级 Web 开发人员，我会说我对 php、html 和 css 有很好的了解。我对javascript知之甚少，但可以使用一点，但不如我对PHP的理解那么好。

您能否为我指明正确的方向以使付款页面看起来正确？我需要元素看起来像注册页面的前 2 部分..

请注意，表单尚未提交，我仍在处理外观。但是一旦集成了braintree，它只需要捕获表单数据并将其提交到数据库即可。

这是表格的链接：http://www.mcr-qr-time.com/registration-form/register.html?plan=1

并查看下面的代码：（我已删除 API 密钥）

    <?php
$plan = $_GET['plan'];
if($plan == "1"){
$amount = "4.99";
}
if($plan == "2"){
$amount = "14.99";
}
if($plan == "3"){
$amount = "34.99";
}
require_once 'braintree-php-3.9.0/lib/Braintree.php';

Braintree_Configuration::environment('production');
Braintree_Configuration::merchantId('#');
Braintree_Configuration::publicKey('#');
Braintree_Configuration::privateKey('#');
if(isset($_POST['submit'])){
    /* process transaction */
    $result = Braintree_Transaction::sale(array(
     'amount' => $amount,
     'creditCard' => array(
     'number' => '(dont know what to do here)',
     'expirationDate' => '(dont know what to do here)'
    )
  ));

if ($result->success) {
  print_r("success!: " . $result->transaction->id);
  } else if ($result->transaction) {
    print_r("Error processing transaction:");
    print_r("\n  code: " . $result->transaction->processorResponseCode);
    print_r("\n  text: " . $result->transaction->processorResponseText);
    } else {
      print_r("Validation errors: \n");
      print_r($result->errors->deepAll());
    }
}

$clientToken = Braintree_ClientToken::generate();

?>

【问题讨论】：

要到达最后一页，只需在字段中输入任何字母，以便继续..
我还上传了braintree-php-3.9.0.tar.gz 并将其解压到我的主目录中，还有什么需要我处理的吗？
您提供的链接与您发布的代码示例不匹配。具体来说，存在输入标签而不是 div，并且不存在托管字段代码。
那是因为braintree不接受我的申请，所以我改了..
我也许可以再次申请，只是想知道是否有人知道我在“/* process transaction */”顶部写“（不知道在这里做什么）”的地方放什么？ ?

【解决方案1】：

_{全面披露：我在 Braintree 工作。如果您还有任何问题，请随时联系我们的support 团队。}

Braintree 使用 Drop-in 或 Hosted Fields 为您提供代表用户付款方式的 nonce。这使您不必处理信用卡号和到期日期信息以及随之而来的 PCI 负担。下面是一个在Braintree_Transaction::sale 中使用随机数的示例：

$result = Braintree_Transaction::sale([
  'amount' => '10.00',
  'paymentMethodNonce' => nonceFromTheClient,
  'options' => [
    'submitForSettlement' => True
  ]

这可能对某些人有用，当使用托管字段或插件时，Braintree 在表单中放置一个隐藏的 nonce 输入，您只需在表单处理脚本中调用它，如下所示：

<?php

require_once 'braintree-php-3.9.0/lib/Braintree.php';

Braintree_Configuration::environment('production');
Braintree_Configuration::merchantId('#');
Braintree_Configuration::publicKey('#');
Braintree_Configuration::privateKey('#');

$paymentMethodNonce = $_POST['payment_method_nonce'];

$result = Braintree_Transaction::sale([
  'amount' => '10.00',
  'paymentMethodNonce' => $paymentMethodNonce,
  'options' => [
    'submitForSettlement' => True
  ]
]);

?>

【讨论】：

$paymentMethodToken 与 $paymentMethodNonce 不同。 Braintree 支付方式令牌是长期存在的令牌，您可以使用它来引用存储在您的保管库中的原始支付方式。付款方式随机数是一次性使用的标识符，用于识别付款方式，直到它存储在保险库中。
