如何将刀片中的两个数字相加Laravel

Question

我需要将刀片视图中显示的两个数字/金额相加，如下图所示

​

我需要显示为666.68 / 1000澳元

这是我的blade代码

    <td>
          @foreach ($team->competitionPayments as $payment)
                {{ $payment->amount }}
          @endforeach

          <br>

         {{ $team->competitionPayments }}
         /
         @foreach ($team->competitions as $total)
          {{ $total->pivot->total_fee .' AUD'}}
         @endforeach
   </td>

下面是我的controller函数

public function detailedRegistrations($competition)
{

    $competitions = $this->competitionsRepo->findOrFail($competition);

    $teams = $competitions->teams()->get();

    $payments = $competitions->payments()->get();

    return view('competitions.detailed-registrations',
                    [
                        'teams'=>$teams,
                        'payments'=>$payments,
                        'competitions'=>$competitions,
                    ]
                );
}

下面是Team model中的competitionPayments关系

public function competitionPayments()
{
    return $this->hasMany(CompetitionPayment::class, 'team_id');
}

请给我一个如何工作的想法

Answer 1

这里的competitionPayments是一个集合，因此您可以对其应用sum()函数，如下所示

<td>
  {{ $payment->competitionPayments->sum('amount') }}
<br>

参考链接https://laravel.com/docs/8.x/collections#method-sum

Answer 2

这是可行的

<td>
    {{ $team->competitionPayments->sum('amount') }}
    /
    @foreach ($team->competitions as $total)
    {{ $total->pivot->total_fee .' AUD'}}
    @endforeach
</td>
