如何在Laravel刀片中显示数组的动态键？

Question

我的控制器是这样的：

public function index(Request $request)
{
    $param = $request->all();
    $data = $this->itemDetailRepository->getData($param);
    return view('item-detail.index', compact('param'))
        ->withItems(count($data)>0?$data:null);
}

如果我调试$data或在laravel（dd($data)）中调试，结果如下：

所以数组$data就是这样的集合和分页

如果单击“属性”部分，则显示如下：

#attributes: array:5 [▼
  "item_number" => "AB-0001"
  "total_quantity" => "1000"
  "location-a" => "500"
  "location-b" => "500"
]

所以数组数据在那里

在这样的视图叶片laravel中：

<table>
    <tr>
        <th>ITEM NUMBER</th>
        <th>TOTAL QUANTITY</th>
        <th>LOCATION-A</th>
        <th>LOCATION-B</th>
    </tr>
        @foreach($items as $item)
        <tr>
            <td>{{ $item->item_number }}</td>
            <td>{{ $item->total_quantity }}</td>
            <td>{{ $item['location-a'] }}</td>
            <td>{{ $item['location-b'] }}</td>
        </tr>
        @endforeach
</table>

有效。但是我数组的关键是动态的。密钥可以更改

因此数组可以像这样更改：

#attributes: array:5 [▼
  "item_number" => "AB-0001"
  "total_quantity" => "500"
  "location-a" => "500"
]

或者可以这样更改：

#attributes: array:5 [▼
  "item_number" => "AB-0001"
  "total_quantity" => "1500"
  "location-a" => "500"
  "location-b" => "500"
  "location-c" => "500"
]

所以位置是动态的

如何在laravel视图刀片中进行设置，使其可以调整为动态数组？

更新

如果我echo '<pre>';print_r($data);'</pre>';die();，则结果如下：

Illuminate\Pagination\LengthAwarePaginator Object
(
    [total:protected] => 2428
    [lastPage:protected] => 1214
    [items:protected] => Illuminate\Database\Eloquent\Collection Object

            [items:protected] => Array

Answer 1

尝试一下：

@php
$counts = array_map('count', $data);
$key = array_flip($counts)[max($counts)];
@endphp
<table>
    <tr>
        @foreach ($data[$key] as $key => $value)
            <th>{{$key}}</th>
        @endforeach
    </tr>
        @foreach($data as $value)
        <tr>
            @foreach ($value as $key => $value)
                <td>{{$value}}</td>
            @endforeach
        </tr>
        @endforeach
</table>

Answer 2

您的问题很令人困惑，如果key是动态的，您还可以发送带有“ key”的数组，并可以发送带有key的数组

//In your controller
$values = array(
    array('item_number' => 'AB-0001','total_quantity' => '500', 'location-a' => '500'),
    array('item_number' => 'AB-0002','total_quantity' => '5000', 'location-a' => '5000'),
    array('item_number' => 'AB-0003','total_quantity' => '2000', 'location-a' => '2000'),
);

$data = 
[
    'keys' => ['item_number', 'total_quantity', 'location_a'],
    'values' => $values
];

return view('some_blade', $data);

在刀片中您可以这样访问

    @foreach($values as $value) 
     <tr>
       @foreach($keys as $k)
            <td>{{ $value[$k]; }}</td>
       @endforeach
    </tr>
    @endforeach

希望有帮助。
