Adding seconds with Carbon
提问by Младен Кари?
The idea is that I need to get end_date from the Auction via this model, which is inside a database, in MySQL timestamp format (I use phpmyadmin, if it matters, ex. 2018-11-14 04:58:07). So when I get the end_date, the idea is to increment it by few seconds (ex. 10 seconds) via Carbon addSeconds() function and then write it again into the DB. Here is the controller where it's done and my Auction model. What happens is that i get the FatalThrowableError 'Call to a member function addSeconds() on integer'. I played around quite a lot and can't seem to find right format for the secs2 variable.
这个想法是我需要通过这个模型从 Auction 中获取 end_date，该模型位于数据库中，采用 MySQL 时间戳格式（如果重要，我使用 phpmyadmin，例如 2018-11-14 04:58:07）。因此，当我获得 end_date 时，想法是通过 Carbon addSeconds() 函数将其增加几秒（例如 10 秒），然后再次将其写入数据库。这是完成的控制器和我的拍卖模型。发生的情况是我收到 FatalThrowableError 'Call to a member function addSeconds() on integer'。我玩了很多，似乎找不到 secs2 变量的正确格式。
Auction.php
拍卖.php
public $id;
public $name;
public $descript;
public $price;
public $pic;
public $end_date;
public $offers;
public $offered_by;
public function get(){
$result =
DB::table('auctions')
->select('*')
->where('id', '=', $this->id)
->first();
return $result;
}
public function increment($id){
$result =
DB::table('auctions')
->where('id', $id)
->update([
'offers' => DB::raw('offers + 1'),
'end_date' => $this->end_date
]);
return $result;
}
AuctionController.php
拍卖控制器.php
public function offer($id, Request $request){
$auction = new Auction();
$auction->id = $id;
$secs = $auction->get()->end_date;
$secs2 = strtotime($secs);
$secs2->addSeconds(120);
$auction->end_date = $secs2;
//dd($secs2);
$auction->increment($id);
}

If you want to use addSecondsmethod, you can't convert your time into number first..
ex:
如果要使用addSeconds方法，则不能先将时间转换为数字。例如：
Carbon::parse($auction->get()->end_date)
->addSeconds(120)
->format('H:i:s');
