Yii : Undefined variable: nama_unit_kerja - variables

Question

I need help. when i open my index it shows that the nama_unit_kerja variable is not defined..
But i've put them in the SiteController. How can i fix this.
This is my SiteController code :
public function actionIndex()
{
//$this->layout = "//layouts/adr/main";
/* $browser = Yii::app()->browser->isMobile();
echo ($browser?'mobile':'not mobile'); exit; */
#session_start();
Yii::app()->user->returnUrl = array('site/index');
$lang = 'en';
if(isset($_SESSION['lang'])) $lang = $_SESSION['lang'];
// renders the view file 'protected/views/site/index.php'
// using the default layout 'protected/views/layouts/main.php'
$this->layout='//layouts/erp/index';
$modelUnitKerja=new UnitKerja('searchKapTarReal');
$modelUnitKerja->unsetAttributes(); // clear any default values
$modelJenisKegiatan=new JenisKegiatan('searchKapTarReal');
$modelJenisKegiatan->unsetAttributes(); // clear any default values
//var_dump($_POST);exit;
if ((isset($_POST['unitKerja'])) or (isset($_POST['year']))){
if(empty($_POST['unitKerja'])){
$unitKerja = 0;
} else {
$unitKerja = $_POST['unitKerja'];
$nama_unit_kerja = UnitKerja::model()->findByAttributes(array("id"=>$_POST['unitKerja']))->nama_unit_kerja;
}
$year = $_POST['year'];
$year_nm = Year::model()->findByAttributes(array("id"=>$_POST['year']))->year;
}else{
$unitKerja = 0;
$year = Year::model()->findByAttributes(array("year"=>date('Y')))->id;
$year_nm = date('Y');
}
$this->render('index',array(
'mJenisKegiatan'=>$modelJenisKegiatan,
'mUnitKerja'=>$modelUnitKerja,
'unitKerja'=>$unitKerja,
'nama_unit_kerja'=>$nama_unit_kerja,
'year'=>$year,
'year_nm'=>$year_nm,
));
}

$nama_unit_kerja = UnitKerja::model()->findByAttributes(array("id"=>$_POST['unitKerja']))->nama_unit_kerja;
hopefully you are getting this error on this line because you are trying to access the property of yii base.
you can use it like
$nama_unit_kerja = UnitKerja::model()->findByAttributes(array("id"=>$_POST['unitKerja']));
$nama_unit_kerja=$nama_unit_kerja->$nama_unit_kerja;
