htmlspecialchars（）期望參數1是字符串，給定的數組。 （laravel）

Question

我是Laravel新手。我已經做了研究，但我似乎無法爲我的代碼找到正確的答案。

所以我有這個控制器

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()); 
    } 
} 

，我的觀點是如此簡單的

<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> 

我檢索我的MongoDB集 '原木' 的loglist。我成功地檢索您可以通過「print_r的」，但是當我看到它在我的觀點嘗試的數據，這是顯示

htmlspecialchars() expects parameter 1 to be string, array given 

這是我的$ loglist的print_r的結果，我successfulyl從MongoDB中檢索到的錯誤 print_r result

這裏是我的var_dump的幾行。

Answer 1

你之前和之後的變量是數組，這就是爲什麼你得到這個錯誤。試試這個代碼：

<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> 

Answer 2

一個或多個返回的對象屬性是數組。嘗試var_dump($logs)
