我试图做一些特定的事情，而不是完全确定如何做到这一点。这就是我要做的事情......
我创建了一个HTML表单，用户在其中指定URL，然后输入验证码。表格的其余部分是隐藏的，并随提交一起发送。
成功提交后，表单将发送到本地处理程序PHP文件，该文件将信息显示给用户以供审阅，并使用另一个提交按钮。处理程序页面上的所有表单数据都是隐藏的，因为它已经被指定了。
第二次提交成功后，相关表单数据将添加到数据库中，并发送到安全的第三方付款表单。我控制的唯一代码是初始表格和确认表格。
form.html - 收集URL和Captcha，然后提交隐藏的表单值 form2.php - 从form.html中获取所有表单值，将其回显给用户进行查看。添加到数据库，并提交到外部表单。
我不完全确定如何使表单2正常工作。当显示表单2时，它不会在第二次提交时添加到数据库，而是在第一次提交时添加它。
以下是第二种形式:(请原谅凌乱的代码！）
<?php
session_start();
if( ($_SESSION['security_code2']==$_POST['security_code2']) && (!empty($_POST['security_code2'])) ) {
//Get user submitted data for review
$x_user1 = $_POST["domain"];
$x_login = $_POST["x_login"];
$x_show_form = $_POST["x_show_form"];
$x_fp_sequence = $_POST["x_fp_sequence"];
$x_fp_hash = $_POST["x_fp_hash"];
$x_amount = $_POST["x_amount"];
$x_currency_code = $_POST["x_currency_code"];
$x_test_request = $_POST["x_test_request"];
$x_relay_response = $_POST["x_relay_response"];
$donation_prompt = $_POST["donation_prompt"];
$x_line_item = $_POST["x_line_item"];
$button_code = $_POST["button_code"];
$x_show_form = $_POST["x_show_form"];
