如何在 laravel blade 中显示数组的动态键？
How can I display dynamic key of array in the laravel blade?
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 $data 或 laravel (dd($data))，结果如下：
所以数组 $data 是 collection 和这样的分页
如果我点击属性部分，它显示如下：
#attributes: array:5 [▼
"item_number" => "AB-0001"
"total_quantity" => "1000"
"location-a" => "500"
"location-b" => "500"
]
所以数组数据在那里
在视图中 blade laravel 像这样：
<table>
<tr>
<th>ITEM NUMBER</th>
<th>TOTAL QUANTITY</th>
<th>LOCATION-A</th>
<th>LOCATION-B</th>
</tr>
@foreach($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。但是我的数组键是动态的。密钥可以改变
所以数组可以像这样改变:
#attributes: array:5 [▼
"item_number" => "AB-0001"
"total_quantity" => "500"
"location-a" => "500"
]
或者可以这样改:
#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

你的问题很混乱，如果键是动态的，你也可以发送一个数组 "key" 并且可以发送一个键这样的数组
//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', $data);
在您的blade中您可以这样访问
@foreach($values as $value)
<tr>
@foreach($keys as $k)
<td>{{ $value[$k]; }}</td>
@endforeach
</tr>
@endforeach
希望对您有所帮助。
试试这个：
@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>

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);
