Question

早上好！我有一个问题，以下json，我接受了这个

当我使用带有此表单的foreach时，信息显示正确

@foreach ($output as $auction)
    @if(count($auction> 0))
        {{$auction}}
    @endif
@endforeach

然而，当我打电话时，Laravel显示错误。

{{$auction->auctions}}

当我提出{{$ auction-＆gt; auctions}} laravel返回错误时，我不知道，有人可以帮助我吗？是OneToMany的关系。

收到这个json的控制器就是这个

public function prodcercanos($lat,$long)
    {

        $cercanos = User::with('municipio')->with('subastas')->get();
        $coordA   = Geotools::coordinate([$lat,$long]); 
        $output = [];
        foreach ($cercanos as $p) {
            if(count($p->subastas)>0){
            $coordB   = Geotools::coordinate([$p->municipio->latitud,$p->municipio->longitud]);
            $distance = Geotools::distance()->setFrom($coordA)->setTo($coordB);
            $dis = $distance->in('km')->haversine();
            $output[$dis] = $p."<p>$dis</p>";
            }
        }       
            ksort($output);

        return view('frontend.prodcercanos2')->with('output',$output)

在JSON中，不维护对象类型。调用$auction->auction不会产生任何结果，因为auction对象可能来自StdObject类型。

此外，我不知道这是您的代码粘贴中的拼写错误，还是您的实时代码中的拼写错误，但是这样：

@if(count($auction> 0))

不行。您的>函数中有比较运算符（count()）。
