我的 Controller 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$data或者在 laravel ( dd($data) ) 中，结果如下:
所以数组$data集合和分页是这样的吗
如果我单击属性部分，它会显示如下:
#attributes: array:5 [▼
"item_number" => "AB-0001"
"total_quantity" => "1000"
"location-a" => "500"
"location-b" => "500"
]
所以数组数据就在那里
在 Laravel View Blade 中，如下所示:
<table>
<tr>
<th>ITEM NUMBER</th>
<th>TOTAL QUANTITY</th>
<th>LOCATION-A</th>
<th>LOCATION-B</th>
</tr>
@foreach($items as $item)
<tr>
<td>{{ $item->item_number }}</td>
<td>{{ $item->total_quantity }}</td>
<td>{{ $item['location-a'] }}</td>
<td>{{ $item['location-b'] }}</td>
</tr>
@endforeach
</table>
它有效。但我的数组键是动态的。 key 可以更改
所以数组可以这样改变:
#attributes: array:5 [▼
"item_number" => "AB-0001"
"total_quantity" => "500"
"location-a" => "500"
]
或者可以像这样改变:
#attributes: array:5 [▼
"item_number" => "AB-0001"
"total_quantity" => "1500"
"location-a" => "500"
"location-b" => "500"
"location-c" => "500"
]
所以位置是动态的
如何在 laravel View Blade 中设置它，以便它可以调整为动态数组？
更新
如果我echo '<pre>';print_r($data);'</pre>';die(); ，结果如下:

最佳答案
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>
