PHPass Assistance

[joshmac]

I've updated an application that I am working on to use PHPass instead of md5. I am using sessions, so when a user logs in, at some point they get reset to another user. I am not sure what is causing this issue, so some help is greatly appreciated. Below is my login function:

function pm_login($username, $password, $remember = NULL) {

        $hasher = new PasswordHash(8, FALSE);

        $user = strtolower(pmdb::connect()->escape($username));
        $pass = pmdb::connect()->escape($password);

        $results = pmdb::connect()->get_row( "SELECT * FROM ". DB ."members WHERE username = '$user'" );

        // Use to set cookie session for domain.
        $cookiedomain = $_SERVER['SERVER_NAME']; 
        $cookiedomain = str_replace('www.', '', $cookiedomain);

            if(isset($_POST['login'])) {
                if($hasher->CheckPassword($pass, $results->password)) {

                do_action( 'pm_login_form_script' );

                $_SESSION['logged'] = 1; // Sets the session.
                $_SESSION['username'] = $results->username; // Sets the username session.
                $_SESSION['userID'] = $results->user_id;
                $_SESSION['remember_me'] = $remember; // Sets a remember me cookie if remember me is checked.

            if(isset($remember)){
                setcookie("pm_cookname", $user, time()+60*60*24*120, "/", $cookiedomain);
                setcookie("pm_cookpass", md5($pass), time()+60*60*24*120, "/", $cookiedomain);
            }
                pm_redirect(PM_URI . "/index.php");

                } else {

                setcookie("pm_cookname", $user, time()+3600*24);
                setcookie("pm_cookpass", md5($pass), time()+3600*24);
            }
                pm_redirect(PM_URI . "/index.php");
        }
          return apply_filter( 'login', $username, $password, $remember );
     }
