我正在试图找出最好的方法来保存数据(这是以前提交的形式)到数据库后,客户已经支付了项目,使用贝宝。这一过程的大致路线:

1) 在实际网站上填写表格-->2)登录Paypal-->3)立即付款(Paypal)-->4)数据插入数据库-->5)返回起点

我已经知道了如何执行步骤1到3和5,但是在执行步骤4时需要一些帮助。据我所知,我需要以某种方式存储数据,然后根据需要保存或丢弃存储的数据。这样做的最佳方式是什么

您的步骤错误

1) 在实际网站上填写表格-->2)登录Paypal-->3)立即付款(Paypal)-->4)数据插入数据库-->5)返回起点

原因在第3步之后,您将如何找到在第一步中填写在表单中的数据,当用户单击提交并离开实际网站并登录到Paypal时,您将丢失表单数据,并且用户也可以对从您的网站购买的产品或服务进行虚假声明,或者对您正在销售的产品或服务进行付款

这一步应该是在与贝宝打交道时

  • 在实际网站上填写From
  • 在表单提交时验证表单数据,如果验证成功,将数据保存到数据库中,并将用户重定向到Paypal
  • 用户登录Paypal并付款
  • 通过Paypal Instant Payment Notification(IPN)(用户仍在Paypal网站上)获取您案例中的付款详细信息,即
    payments.php
    (在IPN中,Paypal发布交易详细信息、金额详细信息等,您需要在步骤5中更新数据库,否则您将无法确定用户支付的产品)
  • 根据Paypal即时付款通知更新数据库中的数据(付款成功、付款失败、付款待定)
  • 使用返回URL
    Return.php将用户重定向回实际网站
  • 在实际网站的返回URL上显示付款详细信息和其他详细信息
  • 旁注:第7步,在这一步中,您可以提供一个唯一的参考号(仅在成功付款时生成),并将该参考号提供给从您的网站购买的用户,否则您可能会与声称已针对任何产品付款的用户打交道

    (与Paypal打交道时,请记住,Paypal总是喜欢消费者而不是商家,因此您必须小心,否则如果欺诈投诉太多,他们会冻结您的帐户)


    就您的代码而言,只需使用
    mysqli\u real\u escape\u string
    mysqli\u real\u escape\u string($\u POST['partment'])那样对表单值进行转义即可
    无需使用PDO您已经在使用
    MySQLi
    在服务器端转义字符串并验证表单输入,足以避免
    SQL注入漏洞

    各地的SQL注入漏洞转换为PDO是否有助于减少漏洞?谢谢。有道理。如果付款失败或被取消,是否可以从数据库中删除数据或将其永久保存在数据库中?付款不会被取消(要取消付款,首先用户必须付款),paypal的付款响应要么成功,要么待定或失败,如果挂起或失败,paypal也会在IPN中的IPNyeah中发布原因,您可以根据PayPals的付款响应对数据做任何您想做的事情简单示例
    if($payment==“failed”){从表中删除,其中id='$id'}
    您将拥有id,因为这是您将作为订单id发送给paypal的内容,paypal将在IPN中将其发回给您,它在每次付款时必须是唯一的,否则paypal将抛出错误,并且不会接受订单和表示发票已付款的付款Hanks.:)关于取消付款,我的意思是,在登录PayPal后,用户可以选择立即付款(开始付款过程)或取消,返回原始页面。
