Hi, I am trying as others to integrate the login system in my cms.
I have problems as well.

My auth script is like this

code
function authenticate()
{
if (isset($_POST["username"]) &&
isset($_POST["password"])) {

        $_SESSION["username"] = $_POST["username"];
        $_SESSION["password"] = md5($_POST["password"]);

        $this->page = "";
        $this->sub = "";
    }

    if (isset($_SESSION["username"]) &&
        isset($_SESSION["password"])) {
        $result = mysql_query("SELECT * FROM `users` WHERE `username` = '".mysql_real_escape_string($_SESSION["username"])."'");

        if (mysql_num_rows($result) != 1) {
            $this->logout();

            $this->page = "authenticate";
            $this->sub = "error";

            return;
        }

        $row = mysql_fetch_assoc($result);

        if ($_SESSION["password"] != $row["password"]) {
            $this->logout();

            $this->page = "authenticate";
            $this->sub = "error";

            return;
        }

        $this->user = $row;

    } else {
        $this->page = "home";
        $this->sub = "";

        return;
    }

}
code

My question is, how is zp_auth going to find out in the cookie which user is logged in? I tried to remove the cookie-check, and add $_zp_loggedin = true; as well as the setcookie into the login script above where you can see $this->user = $row; , but it didn'work.

Any help is much appriciated :]
