如何在会话中存储单选按钮以在另一页上使用？ [英] How to store a radio button in a session for use on another page?

问题描述

因此，我需要在会话中存储所选单选按钮的选项，然后根据该值在不同页面上执行操作。

Page1.php：

 < input type =radioname =personvalue =p1/> Person1 
< ; input type =radioname =personvalue =p2/> Person2 
  

Page2.php

 如果在第一页选择了Person1 
 //如果选择Person2则执行此
一页两页
 //这样做
  

解决方案

您可以通过将表单中的数据发布到您不需要会话的Page2.php页面来完成此操作。

  $ _ POST [person]; 
  

会将数据提取出来，以便您可以执行：

  string person = $ _POST [person] 
 if（person == something）{
 //做点什么
} 
 else {
 //做别的事
} 
  

只有你如果您打算使用多次返回的变量值，则需要一个会话。如果是这种情况，那么你可以在这里找到一个很好的简单教程：

在你的Page2中，基本的东西看起来就像这样.php：

  session_start（）; 
 $ _SESSION [person] = $ _POST [person]; 
  

希望有所帮助！

So I need to store the choice of selected radio button in session and then based on that value perform an action on a different page.

Page1.php:

 <input type="radio" name="person" value="p1"/>Person1
 <input type="radio" name="person" value="p2"/>Person2

Page2.php

if Person1 is selected on page one
  //do this
if Person2 is selected one page two
  //do this

解决方案

You can do this by posting the data in your form through to your Page2.php page you don't need a session.

$_POST["person"];

Will pull the data out so that you can do:

string person = $_POST["person"]
if(person == something){
   //do something
}
else{
  //do something else
}

You only need a session if you intend to use the variable value that is returned on multiple occasions. If that's the case then you can find a good easy tutorial here:

http://www.w3schools.com/php/php_sessions.asp

The basics would look something like this within your Page2.php:

session_start();    
$_SESSION["person"] = $_POST["person"];

Hope that helps!
