Staying logged out

[AL123]

I'm a new coder and am having trouble keeping a user logged out, once they 'log out'

they can go forward and back and still be logged in.

 

<p><a href="../index.php?logout=1">LogOut</a></p>

That is the code I use to log out and forward to the home page.

 

If any one can help that would be great.

session_start();

$dbh=new PDO('mysql:host=localhost;dbname=mnewk2740','mnewk','string');

 

function chk_lgn($lname, $pass)

{

$salt = abc;

$pass = md5($lname.$pass.$salt);

global $dbh;           

$sql = "SELECT UserId ,logname FROM tblPass WHERE logname = '$lname' AND passwd = '$pass' ";

$sth = $dbh->prepare($sql); 

$sth-> execute();

$row = $sth->fetch(PDO::FETCH_ASSOC);

return $row;

}

 

if(isset($_POST['logname']))

{

$UserArr = chk_lgn($_POST['logname'],$_POST['passwd']);

$_SESSION['iden'] = $UserArr['UserId'];

$_SESSION['logname'] = $UserArr['logname'];

}

 

if($_POST && $_SESSION['iden'] !=0)   

{ 

header("Location:../UserPage/index.php"); 

}

 

elseif($_POST && $_SESSION['iden'] == 0)

{

echo "Try Again.";

}

have you tried just:

 

session_destroy();

 

on the logout page to get rid of any settings set, also if your using a cookie login system just get rid of the cookies

I don't see any code there that actually logs the user out, or am I missing something.

 

Try adding

$_SESSION = array();

to your code.
