Question

我正在尝试从控制器传递的视图中获取值。在我的控制器中，我的语法是：

public function index()
    {
        $vehicles=vehicles::orderBy('created_at', 'desc')->get();
        // return $vehicles;
        $ad=ads::orderBy('views','desc')->get();
        // return $ad;

        foreach ($ad as $ads) {     
            # code...
            $popularvehicle[]=vehicles::where('id',$ads->id)->get();
            // echo $popularvehicle;
        }

        return view('index',compact('vehicles','popularvehicle'));
    }

在我的观点中，我试过以下内容：

@foreach($popularvehicle as $popularvehicle)
    {{$popularvehicle->vname}}
@endforeach

它给出了Undefined property: Illuminate\Database\Eloquent\Collection::$vname

的错误

我也试过{!!$popularvehicle['vname']!!}。但它会像未定义的索引一样抛出错误。

当我回显{!!$popularvehicle!!}时，它会提供所需的所有值，例如[{"id":3,"vname":"Pulsar","lotno":"Ba 25 Pa","engine":"150","mileage":"35","kilometers":25000,"price":"120000","negotiable":"Yes","vcondition":"New","used":"3 month","manufacture_year":"2015","description":"Almost New","Company_cid":1,"Users_id":1,"Vehicle_Type_id":1,"created_at":"2017-01-12 15:08:41","updated_at":"2017-01-12 15:08:41"}].

如何获取$popularvehicle的值？谁能帮我？将数组转换为对象有助于解决此问题。如果是，我该怎么办？

Answer 1

错误是因为->试图指向对象$popularvehicles[]的属性是一个数组：

 $ads=ads::orderBy('views','desc')->get();
    foreach ($ads as $ad) {
            $popularvehicles[]=vehicles::where('id',$ad->id)->get()->toArray();
    }

然后，

@foreach($popularvehicles as $popularvehicle)
     @foreach($popularvehicle as $vehicle)
             {{$vehicle['vname']}}
     @endforeach
@endforeach

请注意对命名约定所做的更改。此外，模型名称最好是单数。

Answer 2

考虑复数名称

    $popularvehicles = array(); 
    foreach ($ad as $ads) {
        $popularvehicles[]=vehicles::where('id',$ads->id)->get();
    }
    return view('index',compact('vehicles','popularvehicles'));

并在视图中使用

 @foreach($popularvehicles as $popularvehicle)
    {{$popularvehicle->vname}}
 @endforeach

Answer 3

试试这个：

控制器：

$popularvehicle = vehicles::where('id',$ads->id)->get();
// If you use $popularvehicles[] then you have to use one extra foreach() to retrieve the columns

查看：

@foreach($popularvehicle as $vehicle)
             {{$vehicle->id}}    // for id
             {{$vehicle->vname}} // for name
@endforeach

Answer 4

试试这个：

public function index()
    {
        $vehicles = vehicles::orderBy('created_at', 'desc')->get();
        // return $vehicles;
        $ads = ads::orderBy('views','desc')->get();
        // return $ad;

        foreach ($ads as $ad) {     
            # code...
            $popularvehicles[]=vehicles::find($ad->id);
        }

        return view('index',compact('vehicles','popularvehicles'));
    }

在你看来：

@foreach($popularvehicles as $popularvehicle)
    {{$popularvehicle->vname}}
@endforeach

无法在view.Laravel获取值
