非法字符串偏移＆amp;试图获得非物体的属性（laravel 5.3）

Question

所以我有问题在刀片中打印数据来自控制器的结果，所以：

1. UseController.php：

        $expertCategory = Category::getCategoryByID($user_id);
        $data = [ 'expertCategory' => $expertCategory ];
        return view('cms.user.edit', $data);
   

2. Category.php（models）getCategoryByID（$ user_id）返回结果数组if i dd（expertCategory）;在控制器中，结果是：

   array:9 [▼
      "id" => 1
      "name" => "Beauty"
      "sequence" => 1
      "background_color" => "ffffff"
      "status" => "Active"
      "created_at" => "2017-06-19 09:41:38"
      "updated_at" => "2017-06-19 09:41:38"
      "icon_filename" => "beauty-icon"
      "iconURL" => array:3 [▼
               "small" => "http://localhost:8000/images/category_icons/small/beauty-icon"
              "medium" => "http://localhost:8000/images/category_icons/medium/beauty-icon"
        ]
   ]
   

3. 但是当我想使用foreach打印blade.php中的结果时，代码为：

    @foreach($expertCategory as $expertCat)
      {{ $expertCat->id }}
    @endforeach
   

将返回错误“试图获取非对象的属性”

如果我使用这样的代码：

@foreach($expertCategory as $expertCat) {{ $expertCat['id'] }} @endforeach

它将返回：“非法字符串偏移'id'”

任何人都可以帮助解决这个问题：s？非常感谢！

Answer 1

由于$expertCategory是一个dimensional array，您面临此问题

只需替换此

$expertCategory = Category::getCategoryByID($user_id);
$data = [ 'expertCategory' => $expertCategory ];
return view('cms.user.edit', $data);

使用

$expertCategory = Category::getCategoryByID($user_id);
$data = [ 'expertCategory' => [$expertCategory] ];
return view('cms.user.edit', $data);

然后使用

@foreach($expertCategory as $expertCat)
  {{ $expertCat['id'] }}
@endforeach

在你的刀片中它会对你有用。
