laravel控制器和视图问题

Question

我需要一个get字段值的总和。但我不能也不知道问题出在哪里。

controller代码：

public function index()
{   
$user1 = Auth::user();
$user2 = $user1->client_id;
$withdraws = Withdraw::where('client_id', $user2)->get();

$deposits = Deposit::where('client_id', $user2)->get();
return view('home')->with(compact('deposits', 'withdraws', ));
}

view代码：

@foreach($deposits as $deposit)          
<td id="count-data-td">{{ $deposit->amount }}</td>
@endforeach

Answer 1

return view('home')->with('transfers', array('deposits'=>$deposits, 'withdraws'=>$withdraws));

并查看代码

@foreach($transfers['deposits']) as $deposit)
{{ $deposit->amount }} 
@endforeach

但如果你需要这笔钱，你总是可以这样做：

{{ $transfers['deposits']->sum('amount') }}

在您的情况下：

{{ $deposits->sum('amount') }}

Answer 2

控制器

public function index()
{   
$user1 = Auth::user();
$user2 = $user1->client_id;
$withdraws = Withdraw::where('client_id',$user2)->get();

$deposits = Deposit::where('client_id', $user2)->get();
return view('home')->with(['deposits' => $deposits, 'withdraws',$withdraws]);
}

查看

{{ $deposits->sum('amount') }}
{{ $withdraws->sum('amount') }}

注意：您不需要运行foreach循环来获得总和
