egmap Google Maps Yii not saving data to database - google-maps

Question

I am using egmaps extensions with Yii application it is a very brilliant application. how ever I am having trouble populating database. my database table hotel has two attributes for long and lat. I am not expert in AJAX but i think that ajax is calling controler method. At present I donot have anything in controler method because I donot know what data will come and how?
my code so far is BUT I THINK THIS AJAX IS NOT CALLING THE CONTROLLER SaveCoordinates action
$gMap->zoom = 6;
$mapTypeControlOptions = array(
'position' => EGMapControlPosition::RIGHT_TOP,
'style' => EGMap::MAPTYPECONTROL_STYLE_HORIZONTAL_BAR
);
$gMap->mapTypeId = EGMap::TYPE_ROADMAP;
$gMap->mapTypeControlOptions = $mapTypeControlOptions;
// Preparing InfoWindow with information about our marker.
$info_window_a = new EGMapInfoWindow("<div class='gmaps-label' style='color: #000;'>Hi! I'm your marker!</div>");
// Setting up an icon for marker.
$icon = new EGMapMarkerImage("http://google-maps-icons.googlecode.com/files/car.png");
$icon->setSize(32, 37);
$icon->setAnchor(16, 16.5);
$icon->setOrigin(0, 0);
// Saving coordinates after user dragged our marker.
$dragevent = new EGMapEvent('dragend', 'function (event) { $.ajax({
type:"POST",
url:"'.$this->createUrl('hotel/savecoords').'/'.$model->id.'",
data:({lat: event.latLng.lat(), lng: event.latLng.lng()}),
cache:false,
});}', false, EGMapEvent::TYPE_EVENT_DEFAULT);
if($model->long)
{
// If we have already created marker - show it
$marker = new EGMapMarker($model->lat, $model->long, array('title' => Yii::t('catalog', $model->name),
'icon'=>$icon, 'draggable'=>true), 'marker', array('dragevent'=>$dragevent));
$marker->addHtmlInfoWindow($info_window_a);
$gMap->addMarker($marker);
$gMap->setCenter($model->lat, $model->long);
$gMap->zoom = 16;
}
else
{
// Setting up new event for user click on map, so marker will be created on place and respectful event added.
$gMap->addEvent(new EGMapEvent('click',
'function (event) {var marker = new google.maps.Marker({position: event.latLng, map: '.$gMap->getJsName().
', draggable: true, icon: '.$icon->toJs().'}); '.$gMap->getJsName().
'.setCenter(event.latLng); var dragevent = '.$dragevent->toJs('marker').
'; $.ajax({'.
'"type":"POST",'.
'"url":"'.$this->createUrl('hotel/savecoords')."/".$model->id.'",'.
'"data":({"lat": event.latLng.lat(), "lng": event.latLng.lng()}),'.
'"cache":false,'.
'}); }', false, EGMapEvent::TYPE_EVENT_DEFAULT_ONCE));
}
$gMap->renderMap(array(), Yii::app()->language);

Answer 1

I used POST, and it works. Maybe in your Model's rules params are not specified?

Answer 2

Solved in case other may get stuck I solved it by changing POST to GET and URL Line
url:"'.$this->createUrl('hotel/savecoords').'/'.$model->id.'", '
to
url':'".$this->createUrl('hotel/savecoords', array('id'=>$model->id))."',`
and controller code is
public function actionSaveCoords($id)
{
$model=$this->loadModel($id);
// Uncomment the following line if AJAX validation is needed
//
// $this->performAjaxValidation($model);
if(isset ($_GET['lat']))
$model->lat = $_GET['lat'];
if(isset ($_GET['lat']))
$model->long = $_GET['lng'];
if($model->save())
{
echo 'Thank you for registring your place with '.Yii::app()->name;
}
$this->render('view',array(
'model'=>$model,
));
}
