How to download already save image in yii framework - yii

Question

I am using
$this->widget(
'CMultiFileUpload',
array(
'model' => $model,
'attribute' => 'Image',
'accept' => 'jpg|gif|png|doc|docx|pdf',
'denied' => 'Only doc,docx,pdf and txt are allowed',
'max' => 4,
'remove' => '[x]',
'duplicate'=>'Already Selected',
)
);
for upload multiple images , i save all images into database.But i want to download that saved image.
public function uploadMultifile ($model, $attr, $path)
{
/*
* path when uploads folder is on site root.
* $path='/uploads/doc/'
*/
if ($sfile = CUploadedFile::getInstances($model, $attr)) {
foreach ($sfile as $i => $file) {
$fileName = "{$sfile[$i]}";
$formatName=time() . $i . '_' . $fileName;
$file->saveAs(Yii::app()->basePath . '/' . $formatName);
$ffile[$i] = $formatName;
}
return ($ffile);
}
}
I want to provide link to image and download automatically.
echo CHtml::link($data->image);
Any help appreciated.
I tried
public function actionDownloadImage()
{
$model = $this->loadModel($_GET['id']);
$fileDir = Yii::app()->basePath.'/Img/';
Yii::app()
->request
->sendFile(
$model->image,
file_get_contents($fileDir.$model->image),
$model->image
);
}
but give error..

You haven't defined folder path to save image in uploadMultifile() action. So you can't get your desired images from "Img" named folder. You have to make following changes in uploadMultifile() action:
public function uploadMultifile ($model, $attr, $path)
{
/*
* path when uploads folder is on site root.
* $path='/uploads/doc/'
*/
if ($sfile = CUploadedFile::getInstances($model, $attr)) {
foreach ($sfile as $i => $file) {
$fileName = "{$sfile[$i]}";
$formatName=time() . $i . '_' . $fileName;
$file->saveAs(Yii::app()->basePath . '/Img/' . $formatName); // specify folder path where you have to save image
$ffile[$i] = $formatName;
}
return ($ffile);
}
}
Hope this helps.
