提问by Angelica Rosimo Marcelino
I'm new to Laravel. And i've done researches but i can't seem to find the right answer for my code.
我是 Laravel 的新手。我已经做了研究，但我似乎无法为我的代码找到正确的答案。
So i have this controller
所以我有这个控制器
namespace Modules\Inventory\Http\Controllers;
use Modules\Setup\Init;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use Illuminate\Routing\Controller;
use Illuminate\Support\Facades\DB;
use Modules\Inventory\Entities\mongodb_logs as mongodb_logs;
use Modules\Template;
class ActivityLogsController extends Controller
{
/**
* Display a listing of the resource.
* @return Response
*/
protected $data;
protected $page_title = 'Login';
function setup($vars = null)
{
$Init = new Init;
$vars['page'] = $this->page_title;
$this->data['template'] = $Init->setup($vars);
return $this->data;
}
public function index()
{
$loglists = mongodb_logs::orderBy('date_added', 'desc')->get();
$this->data['loglist'] = $loglists;
return view('inventory::_logs', $this->setup());
}
}
and my view was just this simple
我的观点就是这么简单
<table id="tbl_logs" class="table table-striped table-bordered table-hover">
<thead>
<tr>
<td>Type</td>
<td>User</td>
<td>Date</td>
<td>Message</td>
<td>Before</td>
<td>After</td>
</tr>
</thead>
<tbody>
@if($loglist != null)
@foreach($loglist as $logs)
<tr>
<td>{{$logs->type}}</td>
<td>{{$logs->logged_in_user}}</td>
<td>{{$logs->date_added}}</td>
<td>{{$logs->message}}</td>
<td>{{$logs->before}}</td>
<td>{{$logs->after}}</td>
</tr>
@endforeach
@endif
</tbody>
</table>
I retrieve the loglist from my mongodb collection 'logs'. I successfully retrieved the data you can try it via 'print_r' but when i view it on my view, this is the error that shows
我从我的 mongodb 集合“日志”中检索日志列表。我成功检索了数据，您可以通过“print_r”尝试它，但是当我在视图中查看它时，这是显示的错误
htmlspecialchars() expects parameter 1 to be string, array given
this is the print_r result of my $loglist which i successfulyl retrieved from mongodb print_r result
这是我从 mongodb print_r 结果中成功检索到的 $loglist 的 print_r 结果
here's a few lines of my var_dump.
这是我的 var_dump 的几行。

Your before and after variables are array that's why you getting this error. Try this code:
您的前后变量是数组，这就是您收到此错误的原因。试试这个代码：
<tbody>
@if($loglist != null)
@foreach($loglist as $logs)
<tr>
<td>{{$logs->type}}</td>
<td>{{$logs->logged_in_user}}</td>
<td>{{$logs->date_added}}</td>
<td>{{$logs->message}}</td>
@foreach($logs->before as $before)
<td>{{$before->whatStringYouWant}}</td>
@endforeach
@foreach($logs->after as $after)
<td>{{$after->whatStringYouWant}}</td>
@endforeach
</tr>
@endforeach
@endif
</tbody>
回答by Abdulkareem Mohammed
One or more of the returned object properties is array. try to var_dump($logs)
一个或多个返回的对象属性是数组。尝试var_dump($logs)
