Question

我在控制器中有这个功能：

   public function index()
      {

          $call=45;
          $show = DB::select('select * from users where position="keeper" ');
          return View('index',['users'=>$show,'call'=>$call]);  
     }

在视图中我有这段代码：

  Call: {{$call}}    
  Position: {{$users->position}}     //what is the wrong with this line? everything is fine if i remove this line.

    @foreach ($users as $u)
    {{$u->id}}
    {{$u->name}}
    {{$u->email}} 
     @endif

错误：尝试获取非对象的属性

同样适用于循环：

 @foreach($users as $r)
{{$r->position}}
@endforeach

Answer 1

$ show = DB :: select（'select * from user where position =“keeper”'）;

此查询返回多维对象。这就是为什么你不能像$user->position那样访问它的属性。

要解决此问题，请尝试以下操作：

public function index()
{
     $call=45;
     $show =  DB::select('select * from user where position = "keeper" limit 1')[0];
     return View('index', ['user' => $show, 'call' => $call]); 
}

Answer 2

你可以这样做..

public function index()
  {

    $call=45;
    $show = DB::table('user')->where("position", "keeper")->first();
    return View('index',['user'=>$show,'call'=>$call]);   
 }

检索循环外的行
