Logout Session - not working

144 New Member

hi,

i'm learning and trying to develop a web with php. the logout script of mine seems not working since that after i pressed the logout link. i still get the greeting "welcome, 'username' ".

this is the script in the logout.php that

[PHP]
<html>
<head>
<meta http-equiv="refresh" content="1; URL=index.php">
</head>

<body>
<?
//destroy session and redirect user
session_start();

session_unset();
session_destroy();

//redirect using meta tag
?>
</body>
</html>
[/PHP]

hope someone could help. thx

this is a quote from http://us3.php.net/session_unset
You should go there and read more. Also it depends on what php version your using.

sometimes you might have problems even if using both session_unset and session_destroy. You have to clear the $_SESSION array. I got it working this way:

[PHP]session_unset();
session_destroy();
$_SESSION = array();[/PHP]

Heya, Thesti.

What happens if you refresh index.php after logging out? You might just be seeing a cached version of index.php.

Heya, Thesti.

Try redirecting to index.php?loggedout=true. The loggedout=true part wouldn't affect your logic, but it would prevent the browser from serving the cached version of the page because "index.php" != "index.php?loggedout=true".

i've tried your suggestion to use GET method, but still it doesn't work with Opera. i also have tried to use the no-cache and last-modified things but that doesn't solve the problem too

wonder if this only happen to me. still working to solve this...

JS workaround for the submit button to show as link:

Expand|Select|Wrap|Line Numbers

 
<form action="" method="post">

<input type="hidden" name="logout" value="true" />

<a href="#" onclick="document.getElementById('submitbutton').click();">Logout</a>

<input id="submitbutton" type="submit" name="submit" value="test" style="display: none;">

</form>
