Question

我正在使用表单提交的事件监听器，我需要捕获一个xml文件，打开它并提取他的内容，将它放在一个实体上并将其添加到其他实体的集合中。

现在这是有效的：

    $builder->addEventListener(FormEvents::SUBMIT, function(FormEvent $event){
        $entity = $event->getData();
        if($entity){
            $parent = $event->getForm()->getParent()->getData();
            $gpx = $entity['gpx'];
            if($gpx){
                $xmlGpx = simplexml_load_file($gpx);
                foreach ($xmlGpx->wpt as $pt) {
                    $point = new MonitoringPoint();
                    $point->setPoint(new \CrEOF\Spatial\PHP\Types\Geometry\Point((string) $pt['lat'], (string) $pt['lon']));
                    $point->setAltitude((float) $pt->ele);
                    $point->setDate(($pt->time->count() ? new \DateTime((string)$pt->time) : null ));
                    $point->setAccuracy((float) $pt->hdop);
                    $parent->addMonitoringPoint($point);
                }

                $fileName = $gpx->getClientOriginalName();
                $directory = __DIR__.'/../../../../web/uploads/';
                $date =  new \DateTime();

                $newFileName = md5($gpx->getClientOriginalName().$date->getTimestamp());
                $gpx->move($directory, $fileName);
                $fs = new Filesystem();
                $fs->rename($directory.$fileName, $directory.$newFileName.'.gpx');
                $parent->setGpx($newFileName.'.gpx');

            }
        }
    });

$parent是Monitoring的一个实例，如果我打开$parent，我会看到$point vars已添加到monitoringPoints的集合$entity = new Monitoring($params); $form = $this->createForm(new MonitoringType(), $entity, array( 'action' => $this->generateUrl('my_route'), 'method' => 'POST', )); $form->handleRequest($request); if ($form->isSubmitted() && $form->isValid()) { dump($entity);die; $em = $this->getDoctrine()->getManager(); $em->persist($entity); $em->flush(); }变量，也是gpx。

然后我去看看实体就在持久化之前，在newAction中

public class StoreRecomendadaViewHolder : Object
    {
        public ImageView imgView { set; get; }
        public TextView txtView { set; get; }
    }

并且收藏品是空的！但gpx属性包含正确的值。该集合是否会被重置？

我必须在会话中将点数传递给数组，仍然认为这不是最好的选择，但是有效

$array = [];
foreach ($xmlGpx->wpt as $pt) {
    $point = new MonitoringPoint();
    $point->setPoint(new \CrEOF\Spatial\PHP\Types\Geometry\Point((string) $pt['lat'], (string) $pt['lon']));
    $point->setAltitude((float) $pt->ele);
    $point->setDate(($pt->time->count() ? new \DateTime((string)$pt->time) : null ));
    $point->setAccuracy((float) $pt->hdop);
    $point->setMonitoring($parent);
    array_push($array, $point);
}
$session = new Session();
$session->getFlashBag()->add('array', $array);

在newAction中：

$em = $this->getDoctrine()->getManager();
$session = new Session();
$array = $session->getFlashBag()->get('array');
foreach($array[0] as $point) {
    $point->setMonitoring($entity);
    $entity->addMonitoringPoint($point);
}

$em->persist($entity);
$em->flush();

不知道为什么阵列在控制器中被重置，因为我在提交期间设置了实体中的点

symfony2上的数组收集持久性
