[Resolved] $_session

[mitchell_1078]

Dear all,

  I use logout() func to destroy $_SESSION variable. 

logout()
{
$SESSION=array();
if (isset($COOKIE[session_name()]))
{
unset($_COOKIE[session_name()]);
}
session_destroy();

}
The problem is ..
After logging out , I can't use $_SESSION var again. I mean..

In 1.php, I assign session variable. ( $SESSION['username'] = $username. But in 2.php, $SESSION['username'] is null. Trying to solve this, I use session_register. But I can't.

session_register ("username");
$_SESSION['username'] = $username;

Any help much appreciated. Thanks in advance.

regards,
Mitchell

In 1.php, I start session and assign session variable. It works.

if(session_id())
{
echo session_id(); // display session id
echo $SESSION['username']; // display username
$SESSION['username'] = $username;

}

In 2.php,

if(session_id()) echo session_id(); // display previous session id

if (!$SESSION['username'])
echo "The session data hasn't been passed";

else
echo $SESSION['username'];

It displays " The session data hasn't been passed ".

How can I pass session variable from one page to another ??

... I start session and assign session variable ...

Thats the key thing. Start the session again in 2.php and all will be fine. you will be able to access the same session variable 🙂

I put session_start() in every page.

login.php post username and pwd to first.php.

first.php assign these values into session variable.

second.php extract session variables. At that time, these variables are null although session id exists.

first.php ................

if(session_id())
{
echo session_id(); // display session id

session_register ("username");
session_register ("pwd");

$SESSION['username'] = $username;

$SESSION['pwd'] = $pwd;

echo $SESSION['username']; // display username
echo $SESSION[pwd]; // display pwd
}

second.php

if(session_id())
{
echo session_id(); // display session id
$username = $SESSION['username'];

$pwd = $SESSION['pwd'];

echo "username is ..$username"; // blank

}

Is there any missing point in my page ?? Help me please.

Now I figured it out.

In my first.php, there is <a href> link to allow the user to logout. In this tag onClick event call logout() function. But unexpectedly this function is automatically called. That's why session variable are lost. But session id is left and forwarded to second.php.

Can't I use php code in javascript tag like this ?? Am I too stupid ?? I used like this because I dont know how to call php function in HTML onClick event.

<SCRIPT TYPE="text/javascript">
function logout()
{
<?
$SESSION=array();
if (isset($COOKIE[session_name()]))
{
unset($_COOKIE[session_name()]);
}
session_unset();
session_destroy();

?>

}

</SCRIPT>
