我正在进行登录功能,但遇到了一个我无法弄清楚的错误.

这是我的Model Login类:

class Login {

    private $username;
    private $password;
    private $cxn;       //database object

    function __construct($username,$password)
    {
        //set data
        $this->setData($username, $password);
        //connect DB
        $this->connectToDB();
        // get Data 
    }

    function setData($username, $password)
    {
        $this->username = $username;
        $this->password = $password;
    }

    private function connectToDB()
    {
        include 'Database.php';
        $connect = '../include/connect.php';
        $this->cxn = new database($connect);  
    }

    function getData()
    {
        $query = "SELECT * FROM anvandare WHERE anvandarnamn = '$this->username' AND losenord ='$this->'password'";
        $sql = mysql_query($query);

        if(mysql_num_rows($sql)>0)
        {
            return true;
        }
        else
        {
            throw …
