Or You can import Input facade directly as required,

use Illuminate\Support\Facades\Input;

        $rules = array(
            'name'    => 'required',
        );

        $validator = Validator::make(Input::all(), $rules);

        // if the validator fails, redirect back to the form
        if ($validator->fails()) {
            return Redirect::back()
                ->withErrors($validator) // send back all errors to the login form
                ->withInput();

            $input = input::all();

        } else {

            $company                = New Company();
            $company->name          = Input::get('name');
            $company->user_id       = Input::get('user_id');
            $company->country_id    = Input::get('country_id');
