php – 使用“立即付款”按钮(dwolla)进行访客结账

Guest Checkout仅用于服务器到服务器的结账吗？

是否有使用访客结账的完整示例？ (不仅仅是片段).

这是我的按钮代码：

<a data-key="YOUR-KEY-HERE" 
data-tax="0" data-shipping="0" data-amount="941.00"
data-desc="Invoice: WDGR112612" 
data-name="October - November " class="dwolla_button" 
href="http://mysite.com/paym/?type=success">Continue</a>

表格代码：

<p> <?php
    $key = "YOUR_APPLICATION_KEY";
    $secret = "YOUR_APPLICATION_SECRET";
    $timestamp = time();
    $order_id = 1;

    $signature = hash_hmac('sha1',"{$key}&{$timestamp}&{$order_id}",$secret);
    ?>
    <form accept-charset="UTF-8" action="https://www.dwolla.com/payment/pay"
    method="post">

    <input id="key" name="key" type="hidden" value="abcdefg" />
    <input id="signature" name="signature" type="hidden" value="abcd" />
    <input id="callback" name="callback" type="hidden"
    value="http://www.mywebsite.com/callback.aspx" />
    <input id="redirect" name="redirect" type="hidden"
    value="http://www.mywebsite.com/redirect.aspx" />
    <input id="test" name="test" type="hidden" value="true" />
    <input id="name" name="name" type="hidden" value="Purchase" />
    <input id="description" name="description" type="hidden"
    value="Description" />
    <input id="destinationid" name="destinationid" type="hidden"
    value="812-111-1111" />
    <input id="amount" name="amount" type="hidden" value="1.00" />
    <input id="shipping" name="shipping" type="hidden" value="0.00" />
    <input id="tax" name="tax" type="hidden" value="0.00" />
    <input id="orderid" name="orderid" type="hidden" value="188375" />
    <input id="timestamp" name="timestamp" type="hidden"
    value="1323302400" />

    <button type="submit">Pay Now</button>
    </form>
