在寄存器中添加条款和条件

我想在注册表的验证表单中添加条款和条件，但它不起作用。有谁能帮我一下吗?

<div class="form-group{{ $errors->has('terms') ? ' has-error' : '' }}">
  <label>
    <input type="checkbox" class="form-control" name="terms" value="{{ old('terms') }}" /> Agree with the terms and conditions
  </label>
  <div class="col-md-4">
    @if ($errors->has('terms'))
     <span class="help-block">
       <strong>{{ $errors->first('terms') }}</strong>
     </span>
    @endif
  </div>
</div>

AuthController

protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'company' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'telephone' => 'required|max:255',
            'password' => 'required|min:6|confirmed',
            'g-recaptcha-response' => 'required|captcha',
            'terms' => 'required'
          ]);
    }
