Hi PK95,

[font="Arial"]CUploadedFile::getInstance[color="#222222"][size="2"]([/size][/color]CModel[color="#222222"][size="2"] $model, string $attribute), returns null [/size][/color][color="#222222"][size="2"]if no file is uploaded for the specified model attribute.[/size][/color][/font]

[font="Arial"] [/font]

[font="Arial"][color="#222222"][size="2"]So, you can check it like this:[/size][/color][/font]





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

$model->imageUrl    = null;


if($model->image != null){

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

	$model->image->saveAs($model->imageUrl);}
