issue with image validator rules in laravel 4 - html

Question

I have defined this validating rule for a file(image) in laravel 4 .
'image' => 'image|mimes:jpeg,jpg,bmp,png,gif'
And this is my html code:
{{ Form::label('Image of the product') }} {{ Form::file('image') }}
now , I always get 2 errors while uploading an image even If I chose a png, jpg image
The image must be an image.
The image must be a file of type: jpeg, jpg, bmp, png, gif.
this is the update action that includes image upload :
public function update($id)
{
$product = Product::find($id);
$validator = Validator::make($data = Input::all(), Product::$rules);
if($validator->fails())
{
return Redirect::back()->withErrors($validator)->withInput();
}
$old_img = "";
if(isset($data['image']) and !empty($data['image']))
{
$image = Input::file('image');
$filename = time().'-'.$image->getClientOriginalName();
Image::make($image->getRealPath())->resize(468, 249)->save('public/img/products/'.$filename);
$data['image'] = 'img/products/'.$filename;
$old_img = $product->image;
}
$product->update($data);
File::delete('public/'.$old_img);
return Redirect::route('admin.products');
}

Answer 1

Ensure that your form is a multipart one by adding
'files' => 'true'
to the config array.

Answer 2

first add this to your form tag enctype="multipart/form-data"
second in your validation just 'file'=>'required|mimes:jpeg,png,jpg,gif,svg'
validate mimes and remove image
