客户端与服务器端脚本处理订单 [英] Client-Side vs. Server-Side Scripts to Process Order

问题描述

我正在设计一个网站，允许用户挑选他们披萨的大小和他们放在上面的配料。基于这些选择，我想写脚本到：
1.计算表单提交时的比萨饼成本
2.过程支付（验证信用卡等）

I am designing a website to allow the user to pick the size of their pizza and the toppings they put on it. Based on these choices, I want to write scripts to: 1. calculate the cost for that pizza when the form is submitted 2. Process payment (validate Credit Cards, etc )

在阅读了无数篇文章之后，似乎很明显我必须完成所有支付处理服务器端（php）。对于表单validaton，它将确定用户选择哪些顶部和大小，并确定该比萨的价格，我应该做那个服务器端还是更好地做它的客户端（JavaScript）？谢谢！

After reading countless articles, it appears obvious that I have to do all the payment processing server-side (php). For the form validaton which will determine which toppings and size the user picked and determine a price for that pizza, should I do that server side or is it better to do it client side (javascript) ? Thank you!

推荐答案

可能最好做两点。如果您是在客户端执行此操作，则用户将能够使用内联javascript来更改这些值，这是一个安全漏洞。 Javascript验证比服务器端验证快得多，也更方便。最佳做法是同时做到这一点。

It is probably best to do a little of both. If you do it client-side, the user will be able to alter the values using inline javascript, which is a security vulnerability. Javascript validation is much faster and more convenient than server-side validation. Best practice is do both.
