php - IPN 页面仍然无法工作 PHP mysqli

标签 php mysql mysqli paypal paypal-ipn

现在对此感到非常沮丧。完全按照 Paypal 指南进行操作，但仍然没有得到我需要的东西。

将值从 IPN 插入数据库

这是分步指南:

1: Plan your IPN Solution for both backend and listener: Decide which language you are going to use and review the PayPal IPN listener code samples. Plan what backend tasks need to be done for each type of IPN message (IPN Transaction Types) received. 完成

使用 php 并在开头插入 txn_id、 payment_status 和 user_id

<小时/>

2:实现并验证监听器的 PayPal 请求-响应部分:仅创建监听器的 PayPal 请求-响应部分，以验证所需的握手是否正常工作，无需附加任何后端代码.] 完成

Using sample code that paypal provide from github

IPN 模拟器输出: enter image description here

<小时/>

3:实现监听器后端功能:暂时注释掉监听器代码的请求响应握手部分，因为它已经被验证为工作，然后实现并验证您的后端部分监听器代码正在运行。] 完成

使用此表单来测试插入数据库的查询:

效果非常好

4:测试监听器:取消注释请求-响应代码，以使用各种不同级别的建议 IPN 测试来测试和验证请求-响应握手和后端进程是否按预期协同工作方法，包括PayPal Sandbox环境和IPN模拟器工具。 不完整

将查询和示例代码放在一起，但没有插入数据库

我也遵循了本指南 on how to create an IPN page，但结果仍然相同

注意，这是 1 个模拟 IPN 后的 ipn.log 文件:

最佳答案

我使用电子邮件错误处理来检查我做错了什么

function error_handler($number,$message,$file,$line,$vars){

    $email = "<p>An error ($number) occured on line <strong>$line</strong> and in the file:
    $file.<p>$message</p>";
    $email .= "<pre>" . print_r($vars) . "</pre>";
    $headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
    error_log($email, 1, 'myemail@gmail.com', $headers);
}

set_error_handler('error_handler');

然后它告诉我我缺少一个分号

inlude 'connect.php'

所以

包含“connect.php”；

我这里有两个分号:

("SELECT `transaction_id` FROM `payment` WHERE `transaction_id`='$txn_id'");;

所以

 ("SELECT `transaction_id` FROM `payment` WHERE `transaction_id`='$txn_id'");
