/GaleriController.php

	public function actionCreate()
	{
		$model=new Galeri;
		$model2 =array(new Resimler,);
		
		// Uncomment the following line if AJAX validation is needed
		// $this->performAjaxValidation($model);

		if( isset( $_POST['submitDatas'] ) && isset( $_POST['Galeri'], $_POST['Resimler'] ) )
		{
			$model->attributes=$_POST['Galeri'];
			
			print_r($_POST['Resimler']);
			// PRİNT Array ( [resim_url] => Array ( [0] => ) )
			$valid = $model->validate();
			foreach ( $_POST['Resimler'] as $i => $photo ) {
				$model2[$i] = new Resimler;   
				if ( isset( $_POST['Resimler'][$i] ) )
				    $model2[$i]->resim_url = CUploadedFile::getInstance($model2[$i], "resim_url[$i]" );
				$valid = $valid && $model2[$i]->validate();               
			}
			
			if( $valid && $model->save(false) ) {
			   
			    // Saving each period ( i've to change the date format couse in Italy we use dd/mm/yyyy
			    foreach ($model2 as $i => $photo) {
				$photo->galeri_idgaleriler = $model->idgaleri;
				
				$photo->save(false);
				}	
			if($model->save())
				$this->redirect(array('view','id'=>$model->idgaleri)); 
			}
		}

		$this->render('create',array(
			'model'=>$model,
			'model2' => $model2,
			'photosNumber' => isset($_POST['Resimler']) ? count($_POST['Resimler'])-1 : 0, //How many PhotoEvent the user added
			'update' => false,
		));
