In Controller - public function update_profile(Request $request){

$id = Auth::user()->id;
$data = User::find($id);

$data->name = $request ->name;
$data->email = $request ->email;
$data->phone = $request ->phone;
$data->address = $request ->address;

if ($request->hasFile('image')) {
    $file =$request->file('image');
    $filename = date('YmdHi').$file->getClientOriginalName();
    $file->move(public_path('uploads/admin_images'));
    $data['photo']= $filename;
