Retrieve $_SESSION Value In Input Value

Post a Comment
I am working with a basic registration form , if the user presses submit button , i want to store the input values to a session and also to retain the same user data into the input

Solution 1:

this <?php session_start(); ?> should come right on top of the page before everything else! it should start like this;

 <?php session_start(); ?>
 <!DOCTYPE html>

you should be getting a php error right now saying "Fatal error; headers already sent" or something like that.

the $_SESSION variable will not be available to you if the server did not get the instruction session_start(); in the very first line of your code


Solution 2:

Move this part at the top of your script, just after session_start(); :

 <?php 
   if (isset($_POST['submit']))  
    {
    $_SESSION['user'] = $_POST['user'];
    $_SESSION['email'] = $_POST['email'];
    }
 ?>

Also, as @pythonian29033 said, session_start(); should be written before you output any content.
