Is there a way to upload a phot and generate a thumbnail from that in yii?

I’m just a newby, but here’s how I solved it:

In my model Foto:


public function saveThumb($image,$location)

	{

	    $this->saveResizedImage($image,100,$location);

	}

	

	public function savePreview($image,$location)

	{

	    $this->saveResizedImage($image,225,$location);

	}

	

	public function saveResizedImage($image, $height, $location)

	{

	    $file = imagecreatefromjpeg($image);

	    

	    //Haal de originele breedte en hoogte op

	    $orgwidth = imagesx($file);

	    $orgheight = imagesy($file);


	    //Bereken de nieuwe breedte aan de hand van de nieuwe hoogte

	    $width = ($height/$orgheight)*$orgwidth;


	    //Maak de nieuwe afbeelding

	    $resized = ImageCreateTrueColor($width, $height);


	    //Vul de thumb met de verkleinde foto

	    imagecopyResampled($resized, $file, 0, 0, 0, 0, $width, $height, $orgwidth, $orgheight);

	    

	    //sla de nieuwe afbeelding op

	    imagejpeg($resized,$location);

	    

	    //verwijder data uit geheugen

	    imagedestroy($file);

	    imagedestroy($resized);

	}

In my controller:


public function actionCreate()

	{

		$model = new Foto;


		// Uncomment the following line if AJAX validation is needed

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


		if(isset($_POST['Foto']))

		{

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

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

			if($model->save())

			{

				//sla origineel bestand op

				$model->image->saveAs(Yii::app()->basePath . '/../images/full/' . $model->id . '.jpg');

				$model->image = Yii::app()->basePath . '/../images/full/' . $model->id . '.jpg';

				

				//Sla preview bestand op

				$model->savePreview($model->image, Yii::app()->basePath . '/../images/preview/' . $model->id . '.jpg');

				

				//Sla thumb op

				$model->saveThumb($model->image, Yii::app()->basePath . '/../images/thumb/' . $model->id . '.jpg');

}
