如何将 stdClass 的对象转换为 Laravel 中的数组

Question

我在 Laravel 中尝试显示视图时遇到下一个错误：

"Cannot use object of type stdClass as array (View: C:\xampp\htdocs\mysite\resources\views\cms\contactus.blade.php)".

我的控制器：

public function contactus(){ 

    ContactUS::get_content(self::$data);
    return view('cms.contactus', self::$data); 

}

我的模特：

class ContactUS extends Model
{

public $table = 'contactus';

public $fillable = ['name','email','message']; 

static public function get_content(&$data){ 


        $sql = "SELECT cu.*,name,email,message FROM contactus cu "
            . "ORDER BY cu.created_at DESC ";

        $data['contactusd'] = DB::select($sql); 

     }

}

我的看法：

@extends ('cms.cms_master') 
@section('cms_content')
<div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main">
    <h1 class="page-header">Contact us form information</h1>
    @if($contactusd) 
    <br><br>
    <table class="table table-bordered">  
        <thead>
            <tr>  
                <th>Name</th> 
                <th>Email</th> 
                <th>Message</th> 
            </tr>
        </thead> 
        @foreach($contactusd as $item)  
        <tr>
            <td>{{ $item['name']}}</td> 
            <td>
                <ul>

                    <li> Email: {{ $item['email']}}, Massage: {{$item['message'] }}</li>
                    @endforeach
                </ul>
            </td> 
            <td>{{ $item[created_at]}}</td> 
        </tr>

    </table> 
    @else 
    <p style="font-size: 18px">No information...</p>
    @endif
</div> 

@endsection

Answer 1

试试这个..

$sql = "SELECT cu.*,name,email,message FROM contactus cu "
            . "ORDER BY cu.created_at DESC ";

$data['contactusd'] = DB::select($sql)->get()->toArray();

Answer 2

像这样使用

$data = ContactUS::get_content(self::$data)->toArray();
return view('cms.contactus', $data);

Answer 3

你的 blade 文件中有很多错误

@if($contactusd) 
    <br><br>
    <table class="table table-bordered">  
        <thead>
            <tr>  
                <th>Name</th> 
                <th>Email</th> 
                <th>Message</th> 
            </tr>
        </thead> 
        @foreach($contactusd as $item)  
        <tr>
            <td>{{ $item->name }}</td> 
            <td>
                <ul>

                    <li> Email: {{ $item->email}}, Massage: {{$item->message }}</li>

                </ul>
            </td> 
            <td>{{ $item->created_at}}</td> 
        </tr>
        @endforeach
    </table> 
    @else 
    <p style="font-size: 18px">No information...</p>
    @endif

或

$contactusd = ContactUS::get_content(self::$data)->toArray();
return view('cms.contactus', $contactusd);

Answer 4

如果你获取的数据是在 std class 中，你可以在查看页面中这样写 {{ $item->name }}

如果您获取的数据在 std class 中，你可以在查看页面中这样写 {{$item['message']}}

背面这样写

$sql = "SELECT cu.*,name,email,message FROM contactus cu "
            . "ORDER BY cu.created_at DESC ";

$data['contactusd'] = DB::select($sql)->get()->toArray();
