在我当前的项目中，我对paypal自适应支付也有同样的问题。我已经给了我的

通知url为。在这一页中，我只是简单地编码

$request=$\u POST

邮件（'myid@myaccount“，$请求）

然后我将交易结果发送到我的邮件以查看

---

注意，在我的邮件中，我可以看到交易结果，如果我插入数据库，它将插入，但我无法在我的页面中看到交易结果。尝试将交易结果发送到邮件。

创建paypal_ipn.php文件并将php代码放入其中

对于即时支付通知（IPN）和了解其工作方式有着重要的意义。本指南为您提供了使

通知url

正常工作所需的步骤

Paypal提供了一些验证响应，非常好。您可以使用这些作为自己的起点。

您可以显示您的通知url页面代码吗。。？notify_url页面从paypal获取帖子数据，因此请检查帖子数据。当我使用cmd值作为_xclick时，我会获取详细信息，但当使用_cart时，不会获取。我的notify_url页面作为会话_start（）获取值；要求（“ipn_cls1.php”）$paypal_info=$\u POST；打印（贝宝信息）$paypal\u ipn=新的paypal\u ipn（$paypal\u info）；////echo“status”。$payment_status=trim（$paypal_info['payment_status'）；//Si完成：tout est OK回显“状态1”。$payment\u amount=trim（$paypal\u info['mc\u gross']）；当我使用将事务详细信息发送到邮件时，该页面中出现错误，警告：mail（）希望参数3是字符串，数组在第16行的/home/yesid984/public_html/test/paypal_ipn.php中给出。警告：为foreach（）提供的参数无效在第86行的/home/yesid984/public_html/test/paypal_ipn.php中致命错误：在第98行的/home/yesid984/public_html/test/paypal_ipn.php中调用未定义的方法stdClass:：is_verified（），我没有得到任何mailyes sreeltha mail需要3个参数。邮件（'id@youaccount“，”title“，$request）如何获取自定义值。我将mail（）改为like mail（'id@youaccount“，”标题“，$request）。然后我也没有收到任何邮件。我需要自定义值我如何才能得到它…你是在本地主机或livehey中尝试。我用我的paypal帐户尝试了你的测试表单，并返回了一些数据。我的代码在这里，放在这里并测试它。$req=''；foreach（$_postas$key=>$value）{if（get_magic_quotes_gpc（）==1）{$value=urlencode（stripslashes（$value））；}else{$value=urlencode（$value）；}$req.=“&$key=$value”}print（$req）；什么是支票和支票价格？你在哪里定义了这些？
