public function checkPass(){
$m = new CheckModel();
$d = $m -> where('id = 1')->select();

$name = $_POST['name'];
$pass = $_POST['pass'];
$rem = $_POST['rem'];//the remeber option

if($_SESSION['verify'] == md5($_POST['yanz'])){
if(($name == $d[0]['name']) && ($pass == $d[0]['pass'])){//set the session
session(array('name'=>'islogin','expire'=>3600,'prefix'=>'wj'));
session('isLogin','j');
echo "1";
}
else{
echo "0";
}
}
else{
echo "-1";
}
}

public function ss(){
session(array('name'=>'islogin','expire'=>3600,'prefix'=>'wj'));
session('isLogin','j');
echo session('?isLogin');
echo $_SESSION['wj']['isLogin'];
}
