我已经存储在我的应用程序（LARAVEL 5.4）中，我希望在我的产品主体底部共享一些下载链接，但是要将其隐藏起来，除了谁支付了特定产品的费用。
以下是我如何获取用户数据及其对特定产品的请求的说明：
他们的要求表格：
<form class="form-horizontal" action="{{route('buy_course')}}" method="POST" id="contact_form">

控制器：
public function postbuycourse(Request $request) {
$this->validate($request, array(

Mail::send('emails.buycourse', $data, function($message) use ($data) {

$message->to('xxxxxx@xxxxxx.com');
$message->subject($data['course']);
});
$id = $request->course_id;
$course = Course::findOrFail($id);
Mail::to($request->user())->send(new CourseReceived($course));
Session::flash('flash_message', 'Your Order was sent. Our sell team will contact you shortly.');
return redirect()->back();
}
以下是我向他们展示订单和订单状态的方式，如果付款与否：
