我有2个数组
$ data1和$ data2
当请求$ data2 is_null 或空时,
总是显示错误
Undefined offset: 0
在线
{{$data2[$key]->month}}
我的刀片
@foreach($data1 as $key => $value)
<tr>
<td align="center" style="padding: 10px">{{$data1[$key]->id}}</td>
<td align="center" style="padding: 10px">{{$data1[$key]->Parameters->name}}</td>
<td align="center" align="center" style="padding: 10px">{{$data1[$key]->month}}</td>
@if(isset($data2))
<td align="center" align="center" style="padding: 10px">{{$data2[$key]->month}}</td>
@endif
</tr>
@endforeach
我该如何解决?
最佳答案
您正在检查isset的$data3
,但是您需要检查$data2[$key]
@foreach($data1 as $key => $d1)
<tr>
<td align="center" style="padding: 10px">{{$data1[$key]->id}}</td>
<td align="center" style="padding: 10px">{{$data1[$key]->Parameters->name}}</td>
<td align="center" align="center" style="padding: 10px">{{$data1[$key]->month}}</td>
@if(isset($data2[$key]))
<td align="center" align="center" style="padding: 10px">{{$data2[$key]->month}}</td>
@endif
</tr>
@endforeach
您也可以将
$data1[$key]
更改为$d1
@foreach($data1 as $key => $d1)
<tr>
<td align="center" style="padding: 10px">{{$d1->id}}</td>
<td align="center" style="padding: 10px">{{$d1->Parameters->name}}</td>
<td align="center" align="center" style="padding: 10px">{{$d1->month}}</td>
@if(isset($data2[$key]))
<td align="center" align="center" style="padding: 10px">{{$data2[$key]->month}}</td>
@endif
</tr>
@endforeach
关于laravel - 如果Isset无法与[$ key]配合使用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/49420601/
