将下载的文件存储在Laravel的数据库中

Question

我向客户收取下载的文件后，我需要将该文件存储在数据库的表中。 我现在正在尝试的是不行。我认为我的查询是错误的等等。这是我正在扩展的教程的一部分here本教程使用会话，我需要将它转换为只检查用户的id是否等于数据库中经过身份验证的用户。 / p>

Route::post('/buy/{id}', function($id)
{
/*1. check and see if user is logged in before trying to buy*/

if(Auth::check()) {


    Stripe::setApiKey(Config::get('laravel-stripe::stripe.api_key'));

    //$download = new Download;
    $download = Download::find($id);
    //dd($download);
    //stripeToken is form name, injected into form by js
    $token = Input::get('stripeToken');


    /* 2. If user is logged in charge the card*/
    try {
        $charge = Stripe_Charge::create(array(
            "amount" => $download->price,
            "currency" => "gbp",
            "card" => $token,
            "description" => 'Order: ' . $download->name)
        );


        // If we get this far, we've charged the user successfully

        /* 3.Insert file user downloaded into database purchase table
        only if user id is equal to auth id in users table*/

        $user = DB::table('users')
            ->where('id', 'Auth::user()->id')
            ->exists();

        //dd($user);



        //$download->where('user_id', Auth::user()->id)->exist;



        return Redirect::to('confirmed', '$download');

    } catch(Stripe_CardError $e) {
        // Payment failed
        return Redirect::to('buy/'.$id)->with('message', 'Your payment has failed.');       
    }

}

});
