回答了laravel上的测试后，可以创建可下载pdf证书的部分

如何解决回答了laravel上的测试后，可以创建可下载pdf证书的部分

我正在创建一个部分，其中用户参加两个相同的测试，即知识测试和认证测试，并且我需要在第二次考试中，只有其平均分数高于28分时才能下载pdf证书。他们参加了第一次考试

这是我的测试控制器

  class TestsController extends Controller
{
    public function index()
    {
        $categories = Category::with(['categoryQuestions' => function ($query) {
                $query->orderBy('id')
                    ->with(['questionoptions' => function ($query) {
                        $query->orderBy('id');
                    }]);
            }])
            ->whereHas('categoryQuestions')
            ->get();

        return view('client.test',compact('categories'));
    }

    public function store(StoreTestRequest $request)
    {
        $options = Option::find(array_values($request->input('questions')));

        $result = auth()->user()->userResults()->create([
            'total_points' => $options->sum('points')
        ]);

        $questions = $options->mapWithKeys(function ($option) {
            return [$option->question_id => [
                        'option_id' => $option->id,'points' => $option->points
                    ]
                ];
            })->toArray();

        $result->questions()->sync($questions);

        return redirect()->route('client.results.show',$result->id);
    }
}

这是我的结果控制器

class ResultsController extends Controller
{
    public function show($result_id)
    {
        $result = Result::whereHas('user',function ($query) {
                $query->whereId(auth()->id());
            })->findOrFail($result_id);
        
        return view('client.results',compact('result'));
    }

    public function send($result_id)
    {
        $result = Result::whereHas('user',function ($query) {
                $query->whereId(auth()->id());
            })->findOrFail($result_id);
        $filename = $result->id . '.pdf';
        $pdf = PDF::loadView('client.pdf',compact('result'));
        $pdf->save(storage_path($filename));

        auth()->user()->notify(new SendResultsPdfNotification($result));
        File::delete(storage_path($filename));

        return redirect()->route('client.results.show',$result->id)->withStatus('Your test result has been sent successfully!');
    }
}
