问题描述
更新
我在广告位置的功能
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();
}
我在控制器中有以下方法
I have the following method in the controller
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);
}
我的路线写成如下
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"
);
});
我为那些看到我的anterirormente问题的人尝试了另一种解决方案。
I tried another solution for those who saw my anterirormente question.
在stackoverflow中的几个人进行了很多搜索和怀疑之后，可以达到它，但是当我返回ajax时，他有一张对象类型的照片，这没有任何意义。
After much searching and doubt taken by several guys in stackoverflow could reach it, but when I go return on ajax he has a photo of the object type, this makes no sense.
任何人都知道如何做到这一点？
Anyone know how to do this?
推荐答案
错误是在JasonResponse无法序列化我的类，然后操纵它来迭代jQuery中的结果。
The error was in the JasonResponse could not serialize my class, then manipulated it to iterate power over the result in jQuery.
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);
}
