Question

我有一个网站，允许用户发布类似于Facebook的状态，如果用户试图在同一时间发布该数量，我不想让用户每小时发布最多10个帖子，我想用一条消息重定向用户一小时只允许10个帖子。

我发布状态的代码如下所示：

public function postStatus(Request $request, LaravelFacebookSdk $fb, $checked) 
{
    $checked = $checked;
    $twitterToken = Session::get('access_token');

    $token = Session::get('fb_user_access_token');

    if ($request->has('image_id')) {
        $preloaded = new \Cloudinary\PreloadedFile($_POST['image_id']);
        if (!$preloaded->is_valid()) {
          echo "Invalid upload signature";  //Add a route to page with sorry there was a problem uploading your image.      
        } else {
        //Save Photo URL and User ID to Photo model
        $photorequest = $preloaded->pmsFileName();
        $user = Auth::user();
        $photo = new Photo;
        $photo->image_identifier = $photorequest;
        $photo->user()->associate($user);
        $photo->save();

        $regPhoto = Photo::select('id')->where('image_identifier', $preloaded->pmsFileName())->first();
        $statusPhotoID = $regPhoto->id;
    }


    }else{
        $statusPhotoID = NULL;
    }


    $this->validate($request, [
        'player_url' => 'url|max:255',
        'body' => 'max:1000',
    ]);

    if ($request->has('player_url') || $request->has('body') || $request->has('image_id')) {

        Auth::user()->statuses()->create([
        'body' => $request->input('body'),
        'player_url' => $request->input('player_url'),
        'status_photo_id' => $statusPhotoID,
    ]);

    $userPage = ' http://example.com'; //Do something like {{ route('profile.index', [username = Auth::user()->username])}}
    $tweetLength = 140 - strlen($userPage);

        //Post to Facebook with Image
        if ($checked == 'checked' && isset($photorequest)) {
            try
            {
                $fb->setDefaultAccessToken($token);
                $fb->post('/me/photos', ['url' => cloudinary_url("$photorequest"),'caption' => $request->input('body') . $userPage]);
            }
            catch (Facebook\Exceptions\FacebookResponseException $e)
            {
                // continue to next request;
            }
            //Post to Fb without Image
        } elseif ($checked == 'checked' && !isset($photorequest)) {
            try
            {
                $fb->setDefaultAccessToken($token);
                $fb->post('/me/feed', ['message' => $request->input('body') . $userPage]);
            }
            catch (Facebook\Exceptions\FacebookResponseException $e)
            {
                // continue to next request;
            }
        }
        //Post to Twitter with Image
        if($twitterToken && isset($photorequest)) {

            try
            {
                // Twitter::postTweet(['status' => str_limit($request->input('body') . ' SITE',137), 'format' => 'json']);
                $uploaded_media = Twitter::uploadMedia(['media' => file_get_contents(cloudinary_url("$photorequest"))]);
                Twitter::postTweet(['status' => str_limit($request->input('body') . $userPage,$tweetLength), 'media_ids' => $uploaded_media->media_id_string]);
            }
            catch (Exception $e)
            {
                // continue to next request;
            }
            //Post to twitter without image
        } elseif ($twitterToken && !isset($photorequest)) {
            Twitter::postTweet(['status' => str_limit($request->input('body') . $userPage,$tweetLength), 'format' => 'json']);
        }

        return redirect()->back()->with('info', 'Status Posted.');
    }
        return redirect()->back()->with('info', 'Error Occured, Nothing Posted.');

}

我的表格如下：

在我的created_at我正在使用时间戳（）

实施我想要做的事情，我最好的选择是什么？

只需获取当前时间戳并扣除一小时的秒数。然后你可以通过添加像这样的where子句（当然是伪代码）来获取行数

SELECT COUNT(id) FROM posts WHERE created_at >= $timestamp

您要做的就是检查过去一小时内创建的帖子数是否少于十个。

在Laravel应用中，每小时只允许用户10个帖子
