getting error when i update image in my admin panel - laravel-5

Question

I want to update my product table but when I update my product table, it throws this error :
ErrorException in CreatesController.php line 201: Undefined variable:
name
201 line is this: 'image'=> $name,
My product table contains following fields :
productname,image,price,category_id
This is CreatesController :
public function productupdate(Request $request, $id){
$this->validate($request, [
'productname'=>'required',
'image'=>'image|mimes:jpg,png,jpeg|max:10000',
'price'=>'required',
'category_id'=>'required'
]);
if($request->hasfile('image'))
{
$file=$request->file('image');
$new_name = rand(). '.' .
$path=public_path().'/images';
$name=$file->getClientOriginalName();
$file->move($path, $name);
$data=$name;
}
$data=array(
'productname'=> $request->input('productname'),
'image'=> $name,
'price'=> $request->input('price'),
'category_id'=> $request->input('category_id')
);
Product::where('id', $id)
->update($data);
return redirect('/item')->with('info','Product updated successfuly!');
}

If you are only updating the product details without uploading an image, then if($request->hasfile('image')) becomes false, as $name variable is not getting assigned. Try this..
public function productupdate(Request $request, $id) {
$this->validate($request, [
'productname' => 'required',
'image' => 'image|mimes:jpg,png,jpeg|max:10000',
'price' => 'required',
'category_id' => 'required'
]);
$data = array(
'productname' => $request->input('productname'),
'image' => null,
'price' => $request->input('price'),
'category_id' => $request->input('category_id')
);
if ($request->hasfile('image')) {
$file = $request->file('image');
$path = public_path() . '/images';
$name = $file->getClientOriginalName();
$file->move($path, $name);
$data['image'] = $name;
}
Product::where('id', $id)
->update($data);
return redirect('/item')->with('info', 'Product updated successfully!');
}
