Hello,

How to validate the file upload field in yii...

The uploaded image is save id in folder not in db.

Did you check CFileValidator? You can add validation to your model like this:

array('image', 'file', 'allowEmpty'=>true, 'types'=>'jpg,jpeg,gif,png')

For validation File

Just Add

public function rules()
{
return array(
array('image', 'file', 'types'=>'jpg, gif, png'),
);
}
For validation

hi friend you can also validate your upload image by creating a function in controller
like
public function imageValidate($img, $maxwidth = 1024, $maxheight = 1024)
{

$imagehw = getimagesize($img);
$imagewidth = $imagehw[0];
$imageheight = $imagehw[1];
$imagetype = $imagehw[2];
$valid_types = array(IMAGETYPE_GIF, IMAGETYPE_JPEG, IMAGETYPE_PNG, IMAGETYPE_BMP);
if (in_array($imagetype, $valid_types))
{
if($imagewidth < $maxwidth || $imageheight < $maxheight )
return 1;
}

return 0;
}
and checked it in your model by passing the value.

Rajesh: Don't do stuff like that in the controller, it doesn't belong there as it should know as little as possible of what your model/form needs to work.

You can easily call a custom validation function by using a validation rule like

array('attribute', 'myFunctionName');

It will call the function in the model during validation. You can do that verification either there, or create some sort of file-helper component and call that.
It's a lot cleaner.
