Php paypal IPN不向mysql添加数据?

Php paypal IPN不向mysql添加数据?,php,mysql,paypal,paypal-ipn,Php,Mysql,Paypal,Paypal Ipn,由于某种原因,paypal IPN没有将数据输入mysql数据库!! 我正在使用paypal sandbox,付款通过,并显示在我的sandbox帐户中,但详细信息不会显示在mysql中 这是我的IPN文件。虽然我称之为payments.php,我也使用IPN模拟器指向它,它确实做到了,但它说IPN成功发送了。所以我不知道这里的问题是什么: <?php // Database variables $host = "localhost"; //database location $user

更新:这里是function.php。。我希望这有助于有人帮助我解决这个问题


尝试
Print
ing或
echo
ing替换这些值-
//已付款并成功插入数据库

打印$data['item_name'];
打印$data['item_number']


从那里我可以更新到正确的地方和错误的地方。

看起来你有点“盲目”,因为这是一个“无头”脚本,你不知道它在哪里失败

在不同点添加一些错误日志行,以便检查脚本中的流程。特别是,在执行DB查询之前添加error_log($sql)将把语句打印到错误日志中。拿着这个,试着在数据库中独立运行它。可能是某些表约束失败了,而不是PHP中的错误


在流程的各个点添加日志行,并在这些点打印变量,也将帮助您诊断故障发生的位置,并希望您能够更准确地定位错误。

好吧,我们不想修复您的大型php文件。告诉我们您首先得到的错误。updatePayments函数的内容是什么?updatePayments函数调用过吗?@j0k,老实说,我不认为它是一个“大”php文件。特别是对于那些知道自己在做什么的人。不,我没有任何错误。没有错误,但也不起作用。@beanland,是的,我已经更新了代码并添加了function.php的代码。updatePayment在function.php文件中调用。有什么建议吗?我也有同样的问题。你解决过这个问题吗,OP?谢谢你,但那没用。仍然不起作用。我的意思是,支付通过,因为他们应该,但数据库仍然没有得到更新贝宝IPN!!!再次感谢,我添加了$data=array();当我在我的沙箱帐户中使用IPN模拟器时,我在paypal中遇到了这个错误:IPN交付失败。HTTP错误代码404:未找到。确定。请尝试我提供的上次更新,并删除
$data=array()好的,我已经尝试了你提到的所有选项,但仍然不起作用!!我现在对paypal IPN的事情束手无策。什么都不管用。我不知道该怎么办!!!你好,我是贝宝公司的蒂姆。你可以做一些类似var_导出的事情,然后把整个IPN帖子都寄给你自己。然后你就可以检查哪些数据可以通过,哪些不能通过。我遵循本教程就是为了这个目的,显然它对其他人都有效。。所以为什么不是我:(我已经在这方面工作了18个小时,没有睡眠和食物。我只是不明白为什么会发生这种情况。教程位于这里:
