How To Store A Radio Button In A Session For Use On Another Page?

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: ]; $_SESSION['person'] = $person; ?>

You will have to have the inputs be wrapped inside of a form:

 <form method="post" action="Page2.php">
   <input type="radio" name="person" value="p1"/>Person1
   <input type="radio" name="person" value="p2"/>Person2      
   <input type="submit" value="submit"/>

 </form>

Now you will be able to use that $_SESSION variable on mostly any page, if the session is not destroyed or overwritten.

To retrieve a session value on another page, simply use:

 <?php
   session_start();
   $person = $_SESSION['person'];

 ?>

Solution 2:

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:

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

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

Hope that helps!
