php - 如何在 laravel View 中渲染这个 json

Question

早上好!我有以下 json 的问题，我收到了这个

{"id":51,"nif":"","name":"","cognoms":"","file":"uploads\/$usuario->id\/$fileName","birthday":"0000-00-00","presentacion":"desde","email":"pepes@pepepefgpepepep.com","idempresa":1,"id_poblacion":826,"id_online":0,"created_at":"2015-05-23 23:53:46","updated_at":"2015-05-23 23:53:46","municipio":{"id":826,"idprovincia":29,"poblacion":"Castellitx","poblacionseo":"castellitx","postal":7210,"latitud":"39.562691","longitud":"2.882967"},"bids":[{"id":36,"nombre":"asdsfasd","descripcion":"fsdafsdafsdfsa","precio_salida":170,"cant_actual":172,"id_estado":1,"id_metode_envio":2,"id_metodo_pago":1,"id_creador":51,"id_ganador":null,"id_categoria":34,"id_adquirido":0,"data_inici":"2015-05-30","durada":null,"created_at":"2015-05-24 19:06:19","updated_at":"2015-05-24 20:26:56"}]}<p>233.81707298156</p> {"id":37,"nif":"","name":"","cognoms":"","file":"uploads\/claves.png","birthday":"2015-05-05","presentacion":"asdasdasfafsadfa","email":"","idempresa":1,"id_poblacion":23,"id_online":0,"created_at":"2015-05-22 09:16:33","updated_at":"2015-05-25 08:40:03","municipio":{"id":23,"idprovincia":1,"poblacion":"Barrundia","poblacionseo":"barrundia","postal":1206,"latitud":"42.917229","longitud":"-2.495040"},"bids":[{"id":37,"nombre":"asdffsa","descripcion":"fsadfsdafa","precio_salida":187,"cant_actual":187,"id_estado":1,"id_metode_envio":1,"id_metodo_pago":1,"id_creador":37,"id_ganador":null,"id_categoria":34,"id_adquirido":0,"data_inici":"0000-00-00","durada":null,"created_at":"2015-05-24 19:07:26","updated_at":"2015-05-24 19:07:26"},{"id":38,"nombre":"dsfsdafdsfas","descripcion":"asdfdsagafgfdga","precio_salida":190,"cant_actual":190,"id_estado":1,"id_metode_envio":2,"id_metodo_pago":1,"id_creador":37,"id_ganador":null,"id_categoria":35,"id_adquirido":0,"data_inici":"0000-00-00","durada":null,"created_at":"2015-05-24 19:08:01","updated_at":"2015-05-24 19:08:01"},{"id":39,"nombre":"vcxvcvzxc","descripcion":"sdvzxvcxvz","precio_salida":300,"cant_actual":300,"id_estado":1,"id_metode_envio":2,"id_metodo_pago":1,"id_creador":37,"id_ganador":null,"id_categoria":33,"id_adquirido":0,"data_inici":"0000-00-00","durada":null,"created_at":"2015-05-24 19:08:27","updated_at":"2015-05-24 19:08:27"}]}<p>420.31608445891</p>

当我在这个表单中使用 foreach 时，信息显示正确

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

但是，当我调用 at 时，Laravel 显示错误。

{{$auction->auctions}}

我不知道什么时候我放 {{$auction->auctions}} laravel 返回错误，有人可以帮我解决这个问题吗？是一对多关系。

接收这个 json 的 Controller 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，我不知道这是您粘贴的代码中的拼写错误还是您的实时代码中的拼写错误，但这是:

@if(count($auction> 0))

不会工作。您在 count() 函数中获得了比较运算符 (>)。
