[umerkk]

Hi
I have a Code logout.php, which unser the session and destroy cookies, But it do not destroy the cookies, i have page which checks if cookie is there then show "sdfs" else show "No Cookies", But Even after Logout it show me that cookie is present,

My Logout.php code is

<?php

include("../../includes/session_check.php");
sessioncheck();

if ($_SESSION['loggedin'] == '1') {
$rlReturnUrl = $_REQUEST['rlReturnUrl'];
setcookie ("username");
setcookie ("usernameScreenName");
session_unset();
session_destroy();
header ("Location: $rlReturnUrl");
} else {
echo "No User Currently Logged In";
}
?>

setcookie("screenname", "", -1); can destroy it.

No, This one is also not destroying

setcooki("usernameScreenName", "", -1);

Any Other Suggestions?

To delete a cookie you need to set it with past delete:
[php.net...]

setcookie ("username", "", time() - 3600*365);
setcookie ("usernameScreenName", "", time() - 3600*365);

If this doesn't help, then I can only think about two solutions:

1. You set cookie from a root folder, but delete from a subfolder - it won't work
2. Try to destroy cookie with javascript.

Hope this information will help you

You could also try unset [php.net](), although it should work with what you have above.

Eelix, but unset will not remove a cookie...
Because unset works on a server, whereas cookie is set on user's computer.

That is true. I'm not myself today...Trying to redeem myself ;) -- it will, however, "unset it" for anything after that line in the script; it's only temporary though.

>> setcooki("usernameScreenName", "", -1);

Did you put it correctly or you just mistyped it here:

It should be like this:
>> setcookie("usernameScreenName", "", -1);

I believe the problem exists because of the way you are 'setting' the cookie.

You are only defining one variable for the cookie, the name, ie -

setcookie("userName");

setcookie likes to have at least 3 defined variables, the name, the value of the cookie (whats contained in it) and the amount of time until it should expire. ie -

setcookie("name", "value", "life_of_cookie");

When you miss the "life_of_cookie" out, they begin to behave very unpredictably. In ie it will not write to the users cookie directory. They get stored in memory, and can't be destroyed by the php function.

If you give your original setcookie all values it expects, then you shouldn't have a problem.

I have alrady come up with the solutions

setcookie("usernameScreenName", "", "", "/");

Now it works

So the problem was location - you set it up in the root directory, but wanted to delete from sub. Therefore "/" locating the cookie in root dir could finally delete it.

Glad you got it to work!
