Forms 提交表单（发送包含数据的电子邮件）并重定向到paypal页面

我看到了一些类似的问题，但它们没有得到回答，或者它们不是我想要的

我的网页上有一个简短的表格。当按下“提交”按钮时，表单上的内容将作为电子邮件发送。现在，我想添加一个功能，将用户重新定向到paypal页面，在那里他们可以支付管理费

---

是否有一种方法可以向表单的“提交”按钮添加一些代码，从而将客户重定向到paypal结账（好像他们按下了“立即购买”），或者，是否有一种方法可以定制一个“但它现在”按钮，该按钮还具有提交表单的功能？

否，表单提交可以通过电子邮件或HTTP进行

您可以尝试使用JavaScript伪造某些东西，但这必然会以奇怪而有趣的方式出现，因此正确的方法是处理CGI提交的表单并返回重定向状态代码。

<?php
session_start();
/* Set the variables below */

$contact_us = "contact-form";

$website_url = 'http://www.yourwebsite.com/';

$dummy_email = 'no-reply@yourwebsite.com';
