Question

我从控制器中的数据库获取结果并将它们存储为数组中的对象

    $roleSentinel = Sentinel::findRoleByName($role);
    $permisssionsName = array_keys($roleSentinel['permissions']);
    $permissions = array();

    foreach ($permisssionsName as $permiso) {
        $permissions[] = DB::table('sec_permission')->where('name', '=',$permiso)->get();
    }

    return view('menu', ['role' => $role,'permisos' => $permisos]);

一个对象就像

[{"permission_id":1,"name":"foo","object_id":1,"operation_id":1}]

那么在视图中我试图获取值并打印它们

<b>{{$role}}</b><br>
    @foreach ($permisos as $permiso)
         @foreach ($permiso->name as $name)
            {{$name}}
        @endforeach
    @endforeach

然而我得到了Undefined property: Illuminate\Support\Collection::$name

数组中的每个变量都是一个对象数组。有两种方法可以解决它。

添加另一个foreach：

@foreach ($permisos as $permiso)

    @foreach ($permiso as $perm)
        @foreach ($perm->name as $name)
           {{$name}}
        @endforeach
    @endforeach
@endforeach

或者获得一个包含所有名称的完整集合：

$permissionsName = array_keys($roleSentinel['permissions']);

$permissions = DB::table('sec_permission')->whereIn('name',$permissionsName)->get();

无法访问laravel中的对象属性
