问题描述

我正在尝试在 Laravel 中建立一个访客计数器....

I'm trying to build a visitors counter in Laravel....

我不知道将代码放入其中以便加载到每个页面上的最佳位置是什么……但我将它放在 routes.php 中……

I don't know what the best place is to put the code inside so that it loads on EVERY page... But I putted it inside of the routes.php....

我想我最好把它放在 basecontroller 里面?

I think I'll better place it inside of basecontroller?

但是好吧，我的代码现在看起来像这样:

But okay, My code looks like this now:

    //stats

$date = new DateTime;

$check_if_exists = DB::table('visitor')->where('ip', $_SERVER['REMOTE_ADDR'])->first();

$get_visit_day = DB::table('visitor')->select('visit_date')->where('ip', $_SERVER['REMOTE_ADDR'])->first();

$value = date_create($get_visit_day->visit_date);

if(!$check_if_exists)
{

    DB::table('visitor')->insert(array('ip' => $_SERVER['REMOTE_ADDR'], 'hits' => '1', 'visit_date' => $date));

}else{

    DB::table('visitor')->where('ip', $_SERVER['REMOTE_ADDR'])->increment('hits');
}


$value = date_create($get_visit_day->visit_date);

if ($check_if_exists && date_format($value, 'd') != date('d')) {

    DB::table('visitor')->insert(array('ip' => $_SERVER['REMOTE_ADDR'], 'hits' => '1', 'visit_date' => $date));
}

这很好，但问题是，我的数据库列总是添加一个新值.

That works fine, but the problem is, my database columns always add a new value.

这是我的数据库:

来自表访客".

它不断添加一个新的IP，hit和visit_date...

It keeps adding a new IP, hit and visit_date...

如何仅更新今天(当天)的点击数，如果过了一天，设置新的 IP 值并在该列中计数?

How is it possible to just update the hits from today (the day) and if the day is passed, to set a new IP value and count in that column?

推荐答案

我不是 100% 确定这一点，但你应该能够做这样的事情.它未经测试，可能有更优雅的方式来做，但它是您的起点.

I'm not 100% sure on this, but you should be able to do something like this. It's not tested, and there may be a more elegant way to do it, but it's a starting point for you.

换桌

将 visit_date (datetime) 列更改为 visit_date (date) 和 visit_time (time) 列，然后创建 id 列作为主键.最后，将 ip + date 设置为唯一键，以确保您不能在一天内输入两次相同的 IP.

Change the visit_date (datetime) column into visit_date (date) and visit_time (time) columns, then create an id column to be the primary key. Lastly, set ip + date to be a unique key to ensure you can't have the same IP entered twice for one day.

创建 Eloquent 模型

这只是为了方便:为表创建一个 Eloquent 模型，这样您就不必一直使用 Fluent(查询构建器):

This is just for ease: make an Eloquent model for the table so you don't have to use Fluent (query builder) all the time:

class Tracker extends Eloquent {

    public $attributes = [ 'hits' => 0 ];

    protected $fillable = [ 'ip', 'date' ];
    protected $table = 'table_name';

    public static function boot() {
        // Any time the instance is updated (but not created)
        static::saving( function ($tracker) {
            $tracker->visit_time = date('H:i:s');
            $tracker->hits++;
        } );
    }

    public static function hit() {
        static::firstOrCreate([
                  'ip'   => $_SERVER['REMOTE_ADDR'],
                  'date' => date('Y-m-d'),
              ])->save();
    }

}

现在你应该可以通过调用这个来做你想做的事了:

Now you should be able to do what you want by just calling this:

Tracker::hit();
