我使用Laravel作为我的框架,但它本身并不是一个laravel问题。从数组中,我试图显示每个月的结果,如下所示:
<table>
<tr>
<td>January</td>
</tr>
<tr>
<td>First result for january</td>
<td>Second result for january</td>
</tr>
<tr>
<td>February</td>
</tr>
<tr>
<td>First result for february</td>
<td>Second result for february</td>
</tr>
</table>
在我的控制器中,我得到的结果如下:
$results = Expense::whereBetween('date', array($start, $end))->get();
其中$start
和$end
是我从输入中收集的日期,格式为YYYY-MM-DD
。
在我看来,我会像这样(示例)显示结果:
@foreach($results as $result)
{!! $result->date !!} - {!! $result->expense !!} - {!! $result->amount !!}
@endforeach
但我希望在上面的例子中有它。因此,当我在输入中选择不同的月份时,也会更改视图,因此我无法对其进行硬编码。我基本上需要更改我的foreach以显示一个月,所有结果都来自该月下方,然后显示下一个一个月,等等。
向正确的方向轻推会有所帮助。

我会使用Laravel Collections methods对结果进行分组:
$results = Expense::whereBetween('date', array($start, $end))->get();
$results = $results->groupBy(function($expense)
{
return Carbon\Carbon::parse($expense->date)->month;
});
然后您将得到以下格式的结果:
=> Illuminate\Database\Eloquent\Collection {#2708
all: [
1 => Illuminate\Database\Eloquent\Collection {#1427
all: [
App\Expense {#1410 …27},
App\Expense {#3077 …27},
App\Expense {#1408 …27},
...
],
},
2 => Illuminate\Database\Eloquent\Collection {#1428
all: [
App\Expense {#1310 …27},
App\Expense {#3377 …27},
App\Expense {#1308 …27},
...
],
},
3 => Illuminate\Database\Eloquent\Collection {#1429
all: [
App\Expense {#1810 …27},
App\Expense {#3877 …27},
App\Expense {#1808 …27},
...
],
},
...
],
}
每个密钥代表一个月号。
