[PHP] Mysql Fetch Assoc in una classe PHP

[Giovanni Pili]

Ho provato a correggere in questo modo, ma non cambia niente, anzi colleziono due variabili indefinite in più:

class login extends registrati{
    public $nickname;
    protected $password;
    protected $num_rows;
    protected $assoc;
    
    public function __construct(){
        parent ::__construct();
        $this->nickname=mysql_real_escape_string($_POST['nickname']);
        $this->password=mysql_real_escape_string($_POST['password']);
        $this->query="SELECT * FROM utenti WHERE nickname='{$this->nickname}' AND password='{$this->password}'";
        $this->result=mysql_query($this->query, $this->conn);
        $this->num_rows=@mysql_num_rows($this->result);
        $this->assoc=mysql_fetch_assoc($this->result);
    }
