php – jquery-gmap yii

我正在使用此扩展程序Yii Framework: Jquery-gmap
我是我的应用程序我使用了$gmap-> updateMarkerAddressFromModel& $标记 – &GT capturePosition.

但是当使用$marker-> capturePosition时,$gmap-> updateMarkerAddressFromModel无效,否则$gmap-> updateMarkerAddressFromModel在单独使用时工作正常.

我的代码

<?PHP
                Yii::import('ext.jquery-gmap.*');
                $gmap = new EGmap3Widget();
                $gmap->setSize(400, 234);

                // base options
                $options = array(
                    'scaleControl' => true,
                    'zoom' => 15,
                    'center' => array(0, 0),
                    'mapTypeId' => EGmap3MapTypeId::ROADMAP,
                    'mapTypeControlOptions' => array(
                        'style' => EGmap3MapTypeControlStyle::DROPDOWN_MENU,
                        'position' => EGmap3ControlPosition::TOP_CENTER,
                    ),
                );
                $gmap->setoptions($options);

                // marker with custom icon
                $marker = new EGmap3Marker(array(
                            'draggable' => true,
                        ));
                $marker->address = 'London';
                $marker->capturePosition(
                    // the model object
                    $businessModel,
                    // model's latitude property name
                    'lat',
                    // model's longitude property name
                    'longi',
                    array('drag')
                );
                // tell the gmap to update the marker from the model fields.
                $gmap->updateMarkerAddressFromModel(
                        // the model object
                        $businessModel,
                        array('street','town','country'),
                        array('zoom'=>16)
                );
                $marker->centerOnMap();
                $gmap->add($marker);
                $gmap->renderMap();
                ?>

解决方法:

您没有初始化要传递给视图的模型.

因此,在将模型传递给视图之前,您需要添加
$businessModel = new BusinessModel()我假设这是你的类的名称以及它的引用.我再次假设模型类定义了正确的成员,即lat和long,稍后您将使用它.

看一下下面的例子：我们使用一个带有3个公共成员的地址,纬度,经度和缩放级别的示例

From the jquery-gmap plugin documentation:

Save Marker Position and Map Zoom to Yii Model

Allows capturing the latitude and longitude from a map marker, and the map’s zoom level, to a Yii model object. This is useful if you want to save additional @R_453_4045@ion related to an address in your database.

Address model example :

class Address extends CActiveRecord
{
    public $latitude;
    public $longitude;
        public $mapZoomLevel;

    public function rules()
    {
            return array(
                array('latitude,longitude', 'numerical'),
                array('mapZoomLevel', 'numerical', 'integerOnly'=>true),
            );
    }
}

In your view file :

// init the model (usually passed to view)
$address = new Address();


// init the map
$gmap = new EGmap3Widget();
$gmap->setoptions(array('zoom' => 14));

// create the marker
$marker = new EGmap3Marker(array(
    'title' => 'Draggable address marker',
    'draggable' => true,
));
$marker->address = '10 Downing St, Westminster, London SW1A 2, UK';
$marker->centerOnMap();

// set the marker to relay its position @R_453_4045@ion a model
$marker->capturePosition(
     // the model object
     $address,
     // model's latitude property name
     'latitude',
     // model's longitude property name
     'longitude',
     // Options set :
     //   show the fields, defaults to hidden fields
     //   update the fields during the marker drag event
     array('visible','drag')
);
$gmap->add($marker);

// Capture the map's zoom level, by default generates a hidden field
// for passing the value through POST
$gmap->map->captureZoom(
    // model object
    $address,
    // model attribute
   'mapZoomLevel',
   // whether to auto generate the field
   true,
   // HTML options to pass to the field
   array('class' => 'myCustomClass'),
);

$gmap->renderMap();
