Session problem

Hi!

I have a problem with sessions. When I try:
Code:
<?php
  $username = (string) $_POST['username'];
  session_start();
?>


and I set value of session I can see it on the page:
Code:
<?php
  $_SESSION[username] = $username;
  echo "username = ".$_SESSION[username];
?>


but when I try to get the value on some other page it doesn’t work.

How can I solve it?

Thanks.

try using this...

Code:

<?php
Session_start();
$username = $_POST['username'];
session_register("username"); //register's variable 'username'
?>


Then on the request pages try...

Code:

<?php
Session_start();
  $_SESSION[username] = $username;
  echo "username: $username";
?>

Yeah, you need the Session_start(); on every page.

Thanks, i forgot to mention that.

the Session_start(); needs to be on every page you request the variable and its MUST appear before any html output otherwise you will get errors.

you're missing quotes on your indexes. should be $_SESSION['username']

why not just directly assign the variable?

Code:
<?php
  session_start();
  $_SESSION['username'] = $_POST['username'];

  echo '$_SESSION['username'] ='.$_SESSION['username'];
?>

Thank you for replies but it’s not working… I can see the values on the page where I assigned them but I can’t pass data to another page. Crying or Very sad

Try using GET insted of POST. Might solve it depending on how you've setup your form to submit the variables..

GET and POST are not in correlation with sessions. Sessions are independent system of data handling.


First page:
Code:
<?php
session_start();
$_SESSION['username'] = $_POST['username']; 
?>


Second page:
Code:
<?php
session_start();
echo @$_SESSION['username'];
?>

As what other suggest this code work's fine
Code:

<?
session_start();

session_register('username');

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

echo "Your Username is : ".$_SESSION['username'];
?>


I think this code really work. Session is use as to stored temporary variable on every session if you wish to get the value into the other page all you need is to put a session_start(); on that certain page where you want to view or retrieve the value that you store in your session.
