unzip files lalu memasukkan datanya ke tabel yg berbeda

selamat siang para coders… saya newbie banget di yii nih.

saya lagi buat photo gallery, jadi bisa create event gitu, nah dalam create event bisa langsung unzip file zip yg diupload.

pertanyaan saya, gimana caranya ambil filename dari foto2 tsb lalu dimasukkan ke artibutnya. berikut saya lampirkan tabel nya

|–detail_event–|

id_det_event PK

id_event FK

event_name

event_date

event_venue

img_zip

|–gallery_photo–|

id_galphoto PK

id_det_event FK

path

caption

nah, bagaimana ya cara ambil file name si foto trus masukin ke path, tapi di 1 form di detailevent.

Terima kasihhh semua Mohon bantuaannya

Lampiran

DetailEventController.php

kode pada actionCreate

public function actionCreate()

	{

		$model=new DetailEvent;

		$model2=new GalleryPhoto;


		// Uncomment the following line if AJAX validation is needed

		// $this->performAjaxValidation($model);


		if(isset($_POST['DetailEvent'], $_POST['GalleryPhoto']))

		{

			$model->attributes=$_POST['DetailEvent'];

			$model2->attributes=$_POST['GalleryPhoto'];


			$valid=$model->validate();

			$valid=$model2->validate() && $valid;


			if($valid)

			{

				$model->img_zip=CUploadedFile::getInstance($model,'img_zip');

				if($model->save(false))

					$model->img_zip->saveAs(Yii::app()->basePath .'/../images/zip/' . $model->event_name.'.zip');


				$this->unzip_file("images/zip/$model->event_name.zip" , $model->event_name);


				//$model->save(false);

				$model2->id_det_event=$model->id_det_event;


				$model2->save(false);


				$this->redirect(array('view','id'=>$model->id_det_event));

			}

		}


	


		$this->render('create',array(

			'model'=>$model,

			'model2'=>$model2,

		));


		


	}

kode pada action unzip

function unzip_file($file, $event){  

   	 	// create object  

    	$zip = new ZipArchive() ; 

    	$model = new DetailEvent;

    	$model2 = new GalleryPhoto;

    	$newfolder = $model->event_name;


    	$destination = ('images/gallery/'.$event. '/') ;

    	// open archive  

    	if ($zip->open($file) !== TRUE) 

    	{  

        	die ('Could not open archive:' .$file);  

    	}  

    	else

    	{

    		for($i=0; $i<$zip->numFiles; $i++)

  		{

    			$model2->path = $zip->getNameIndex($i);

      		}

    	}

       	

    	// extract contents to destination directory  

    	$zip->extractTo($destination);  

    	// close archive  

    	$zip->close();    

	}

pada kode di atas tidak terjadi apa2… bagaimana ya solusinya? terima kasih
