设置PayPal返回网址并使其自动返回? [英] Setting PayPal return URL and making it auto return?

问题描述

这是针对以下问题的后续问题: PHP:简便的方法开始PayPal结帐?

This is a follow up question to: PHP: Easy way to start PayPal checkout?

所以，我的问题是我指定了返回URL.但是，在使用PayPal付款后，我看到的屏幕上显示:

So, my problem is that I am specifying the return url. However, after paying with PayPal, I end up at a a screen that says:

您刚完成付款. XXXX，您刚完成付款. 您为此付款的交易ID为:XXXXXXXXXXXXX.

You just completed your payment. XXXX, you just completed your payment. Your transaction ID for this payment is: XXXXXXXXXXXXX.

我们将向[e-mail]发送确认电子邮件.此交易将在您的对帐单上显示为PAYPAL.

We'll send a confirmation email to [e-mail]. This transaction will appear on your statement as PAYPAL.

Go to PayPal account overview

我需要它不显示此屏幕，而直接转到返回URL.我有:

I need it to not show this screen and go directly to the return URL. I have:

• 设置返回"变量
• 将"rm"变量设置为:2(根据指南="使用POST方法将买方的浏览器重定向到返回URL，并且包括所有付款变量")

• Set the "return" variable
• Set the "rm" variable to: 2 (which according to the guide = "the buyer’s browser is redirected to the return URL by using the POST method, and all payment variables are included")

事实上，这是我的完整表格:

In fact, here's my whole form:

<form method="post" action="https://www.sandbox.paypal.com/cgi-bin/webscr">
  <input type="hidden" value="_xclick" name="cmd">
  <input type="hidden" value="[e-mail]" name="business">
  <!-- <input type="hidden" name="undefined_quantity" value="1" /> -->
  <input type="hidden" value="Order at The Greek Merchant:&lt;Br /&gt;Goldfish Flock BLG&lt;br /&gt;" name="item_name">
  <input type="hidden" value="NA" name="item_number">
  <input type="hidden" value="22.16" name="amount">
  <input type="hidden" value="5.17" name="shipping">
  <input type="hidden" value="0" name="discount_amount">        
  <input type="hidden" value="0" name="no_shipping">
  <input type="hidden" value="No comments" name="cn">
  <input type="hidden" value="USD" name="currency_code">
  <input type="hidden" value="http://XXX/XXX/XXX/paypal/return" name="return">
  <input type="hidden" value="2" name="rm">      
  <input type="hidden" value="11255XXX" name="invoice">
  <input type="hidden" value="US" name="lc">
  <input type="hidden" value="PP-BuyNowBF" name="bn">
  <input type="submit" value="Place Order!" name="finalizeOrder" id="finalizeOrder" class="submitButton">
</form>

有什么办法让我自动回到过去吗?另外，如何将付款结果返回到我的网站，以便可以更新数据库?什么是IPN?

Any idea how I can get it to automatically go back? Alternatively, how do I get the result of the payment back to my website so I can update the database? What is IPN?

推荐答案

您必须在PayPal帐户中启用自动返回功能，否则它将忽略return字段.

You have to enable auto return in your PayPal account, otherwise it will ignore the return field.

IPN用于即时付款通知.与自动返回相比，它将为您提供更可靠/有用的信息.

IPN is for instant payment notification. It will give you more reliable/useful information than what you'll get from auto-return.

有关IPN的文档位于: https://www.x.com/sites/default/files/ipnguide.pdf

Documentation for IPN is here: https://www.x.com/sites/default/files/ipnguide.pdf

IPN的在线文档: https://developer.paypal.com/docs/经典/ipn/gs_IPN/

Online Documentation for IPN: https://developer.paypal.com/docs/classic/ipn/gs_IPN/

一般过程是您在请求中传递一个notify_url参数，并设置一个处理和验证IPN通知的页面，贝宝(PayPal)将向该页面发送请求，以在您进行付款/退款/等操作时通知您.经过.然后，该IPN处理程序页面将是更新数据库以将订单标记为已付款的正确位置.

The general procedure is that you pass a notify_url parameter with the request, and set up a page which handles and validates IPN notifications, and PayPal will send requests to that page to notify you when payments/refunds/etc. go through. That IPN handler page would then be the correct place to update the database to mark orders as having been paid.
