$model->image->saveAs('path/to/localFile');
// redirect to success page
}
}
$this->render('create', array('model'=>$model));

Answer 1

Try this for your controller code :
public function actionCreate()
{
$model=new Uploadinfo;
if(isset($_POST['Uploadinfo']))
{
$model->attributes=$_POST['Uploadinfo'];
$file=CUploadedFile::getInstance($model,'image');
if($model->validate() && $model->save())
{
$model->image->saveAs('path/to/localFile');
}
}
$this->render('create', array('model'=>$model));
}

You should set allow_empty=>true for it to work watch this post link:
array('image', 'file', 'types' => 'jpg, txt, pdf, gif, png', 'allowEmpty'=>true,'on'=>'update', 'on'=>'insert'),
and in your view
<?php
$form = $this->beginWidget('CActiveForm', array(
'id'=>'uploadinfo-form',
'enableAjaxValidation'=>true,
'enableClientValidation' => true,
'htmlOptions' => array('enctype' => 'multipart/form-data'),
)); ?>
