UPDATE

我在廣告的庫函數

public function findByExceptOwner($paramFetcher) 
    { 

     $query = $this->getEntityManager()->createQueryBuilder('ad'); 

     // parâmetros iniciais da query: status, departure de destination 
     $query->select('ad'); 

     if(array_key_exists('type', $paramFetcher)){ 
      $query->from('DelivveWebBundle:' . $paramFetcher['type'], 'ad'); 
     }else{ 
      $query->from('DelivveWebBundle:Ad', 'ad'); 
     } 

     $query 
      ->where('ad.owner <> :ownerId') 
      ->andWhere($query->expr()->eq('ad.status', ':status')) 
      ->andWhere('ad.dateFinal <= :today') 
      ->setParameter('ownerId', $paramFetcher['ownerId']) 
      ->setParameter('status', 'new') 
      ->setParameter('today', new \DateTime("now")); 

     if (array_key_exists('departure',$paramFetcher)) { 
      $departureArray = preg_split('/ - /', $paramFetcher['departure']); 
      $departureCityArray = preg_split('/,/', $departureArray[count($departureArray) - 2]); 
      $departureUFArray = preg_split('/,/', $departureArray[count($departureArray) - 1]); 
      $departure = $departureCityArray[count($departureCityArray) - 1] . ' - ' . $departureUFArray[0]; 
      $query 
       ->andWhere($query->expr()->like('ad.departure', ':departure')) 
       ->setParameter('departure', "%{$departure}%"); 
     } 

     if (array_key_exists('destination',$paramFetcher)) { 
      $destinationArray = preg_split('/ - /', $paramFetcher['destination']); 
      $destinationCityArray = preg_split('/,/', $destinationArray[count($destinationArray) - 2]); 
      $destinationUFArray = preg_split('/,/', $destinationArray[count($destinationArray) - 1]); 
      $destination = $destinationCityArray[count($destinationCityArray) - 1] . ' - ' . $destinationUFArray[0]; 
      $query 
       ->andWhere($query->expr()->like('ad.destination', ':destination')) 
       ->setParameter('destination', "%{$destination}%"); 
     } 

     // raio de busca com centro nas coordenadas de departure 
     if (array_key_exists('departure_latitude', $paramFetcher) && array_key_exists('departure_longitude', $paramFetcher) && array_key_exists('radius', $paramFetcher)) { 
      $query 
       ->andWhere('earth_distance_operator(earth_box(ll_to_earth(:departure_lat, :departure_lon), :radius), \'@>\', ll_to_earth(ad.departureLatitude, ad.departureLongitude)) = true') 
       ->setParameter('departure_lat', floatval($paramFetcher['departure_latitude']), \Doctrine\DBAL\Types\Type::FLOAT) 
       ->setParameter('departure_lon', floatval($paramFetcher['departure_longitude']), \Doctrine\DBAL\Types\Type::FLOAT) 
       ->setParameter('radius', floatval($paramFetcher['radius'])/1.609, \Doctrine\DBAL\Types\Type::FLOAT); 
     } 

     // raio de busca com centro nas coordenadas de destionation 
     if (array_key_exists('destination_latitude', $paramFetcher) && array_key_exists('destination_longitude', $paramFetcher) && array_key_exists('radius', $paramFetcher)) { 
      $query 
       ->andWhere('earth_distance_operator(earth_box(ll_to_earth(:destination_lat, :destination_lon), :radius), \'@>\', ll_to_earth(ad.destinationLatitude, ad.destinationLongitude)) = true') 
       ->setParameter('destination_lat', floatval($paramFetcher['destination_latitude']), \Doctrine\DBAL\Types\Type::FLOAT) 
       ->setParameter('destination_lon', floatval($paramFetcher['destination_longitude']), \Doctrine\DBAL\Types\Type::FLOAT) 
       ->setParameter('radius', floatval($paramFetcher['radius'])/1.609, \Doctrine\DBAL\Types\Type::FLOAT); 
     } 

     return $query->getQuery()->getResult(); 
    } 

我在控制器下面的方法

public function searchAdsAction(Request $request) 
{ 
    $this->denyAccessUnlessGranted('ROLE_USER', null, 'Unable to access this page!'); 

    $em = $this->getDoctrine()->getManager(); 

    $owner = $this->getUser(); 

    $parameter = array(); 
    $parameter["departure_latitude"] = $request->request->get('departure_lat'); 
    $parameter["departure_longitude"] = $request->request->get('departure_long'); 
    $parameter["radius"] = Constant::RADIUS; 
    $parameter["ownerId"] = $owner->getId(); 
    $entities = $em->getRepository('DelivveWebBundle:Ad')->findByExceptOwner($parameter); 

    return new JsonResponse($entities); 
} 

我的路線寫成如下

search_ads: 
pattern: /ad/search 
defaults: { _controller: DelivveWebBundle:Ad:searchAds } 

我的功能AJAX

$(window).load(function() { 
     var url = window.location.href; 
     var urlArray = url.split("/"); 
     var path = urlArray[0]+"//"+urlArray[2]; 

     var departureLatitude = $("#bundle_ad_departureLatitude").val(); 
     var departureLongitude = $("#bundle_ad_departureLongitude").val(); 

     $.post(path+"{{ path('search_ads') }}", 
      {departure_lat: departureLatitude, departure_long: departureLongitude}, 
      function (entities){ 
       alert("success "); 
       console.log(entities); 

       $(".panel-foot-information").remove(); 

       $div = "<div class='panel-foot-information row big-not-visible'>"; 

       if (entities != null){ 
       $div = $div + "<table id='ads'><thead><tr><th>Departure</th><th>Destination</th></tr></thead><tbody>"; 
       $.each(entities, function(key, value) { 
        $div = $div + "<tr class='ad-tr'>"; 
        $div = $div + "<td class='hidden'><input type='hidden' id='idLat' value="+ value.departureLatitude +"/></td>"; 
        $div = $div + "<td class='hidden'><input type='hidden' id='idLong' value="+ value.departureLongitude +"/></td>"; 
        $div = $div + "<td>"+ value.owner.username +"</td>"; 
        $div = $div + "<td>"+ value.departure +"</td>"; 
        $div = $div + "<td>"+ value.destination +"</td>"; 
        $div = $div + "<td class='packageType'>"+ value.packageType +"</td>"; 
        $div = $div + "<td class='transportation'>"+ value.transportation +"</td>"; 
        $div = $div + "<td class='price'>"+ value.price +"</td>"; 
        $div = $div + "<td class='date'>"+ value.date + " - " + value.dateFinal +"</td>"; 
        $div = $div + "</tr>"; 
        alert($div) 
       }); 
       $div = $div + "</tbody></table></div>"; 
       } 
       $div = $div + "</div>"; 
       $(".panel-middle").append($div); 
      }, "json" 
     ); 
    }); 

我想對於那些誰看到我anterirormente問題的另一個解決方案。

經過很多人在stackoverflow中搜索和懷疑可以達到它，但是當我回到ajax上時，他有一張對象類型的照片，這沒有任何意義。

任何人都知道如何做到這一點？

錯誤發生在JasonResponse無法序列化我的類，然後操縱它來迭代jQuery結果的權力。

public function searchAdsAction(Request $request) 
{ 
    ... 
    $data = array(); 
    foreach($entities as $ad){ 
     $adArray = array(); 
     $adArray["departureLatitude"] = $ad->getDepartureLatitude(); 
     $adArray["departureLongitude"] = $ad->getDepartureLongitude(); 
     $adArray["owner_username"] = $ad->getOwner()->getUserName(); 
     $adArray["departure"] = $ad->getDeparture(); 
     $adArray["destination"] = $ad->getDestination(); 
     $adArray["packageType"] = $ad->getPackageType(); 
     $adArray["price"] = $ad->getPrice(); 
     $data[] = $adArray; 
    } 

    return new JsonResponse($data); 
}
