PHP在多个页面上传递多个变量 [英] PHP passing multiple variables across multiple pages

问题描述

我的网站涉及用户通过几页表单提交数据。我可以将在一页上提交的数据直接传递到下一页，但是我该如何将它发送到页面之后呢？这是我正在做的一个非常简化的版本。

第1页

  echo'< form action ='page2.php'method ='post'> 
请输入您的姓名：< input type ='text'name = 'Name'/> 
< input type ='submit'value ='Submit'/>< / form>; 
？> 
  

第2页：

 <？php 
 $ name = $ _ POST [Name]; 
 echoHello $ name！< br /> 
< form action ='page3.php'method ='post'> 
请输入您的请求：< input type ='text'name ='Req'/> 
< input type ='submit'value ='提交'/>< / form>; 
？> 
  

第3页：

 <？php 
 echo谢谢您的请求，$ name！; 
？> 
  

最后一页应该显示用户的名字，但显然它不起作用，因为我没有没有将该变量传递给页面。由于复杂的原因，我无法在同一页面上提交所有数据，因此我需要将所有内容分开。那么我怎样才能得到这个变量和其他的结果？

解决方案

使用会话：

$

  
 
  session_start（）;  $ _SESSION ['name'] = $ _POST ['name']; 
  

然后在第3页，您可以回显 $ _ SESSION ['name']

My website involves a user submitting data over several pages of forms. I can pass data submitted on one page straight to the next page, but how do I go about sending it to pages after that? Here's a very simplified version of what I'm doing.

Page 1:

<?php
echo "<form action='page2.php' method='post'>
Please enter your name: <input type='text' name='Name'/>
<input type='submit' value='Submit'/></form>";
?>

Page 2:

<?php
$name=$_POST["Name"];
echo "Hello $name!<br/>
<form action='page3.php' method='post'>
Please enter your request: <input type='text' name='Req'/>
<input type='submit' value='Submit'/></form>";
?>

Page 3:

<?php
echo "Thank you for your request, $name!";
?>

The final page is supposed to display the user's name, but obviously it won't work because I haven't passed that variable to the page. I can't have all data submitted on the same page for complicated reasons so I need to have everything split up. So how can I get this variable and others to carry over?

解决方案

Use sessions:

session_start(); on every page

$_SESSION['name'] = $_POST['name'];

then on page3 you can echo $_SESSION['name']
