LeafLet Extension for Yii2

Extension library to display interactive maps with LeafletJs

Installation

The preferred way to install this extension is through composer. This requires the composer-asset-plugin, which is also a dependency for yii2 – so if you have yii2 installed, you are most likely already set.

Either run

composer require 2amigos/yii2-leaflet-extension:~1.0

or add

"2amigos/yii2-leaflet-extension" : "~1.0"

to the require section of your application's composer.json file.

Usage

One of the things to take into account when working with LeafletJs is that we need a Tile Provider. Is very important, if we fail to provide a Tile Provider Url, the map will display plain, without any maps at all.

The following example, is making use of MapQuest:

// first lets setup the center of our map
$center = new dosamigos\leaflet\types\LatLng(['lat' => 51.508, 'lng' => -0.11]);

// now lets create a marker that we are going to place on our map
$marker = new \dosamigos\leaflet\layers\Marker(['latLng' => $center, 'popupContent' => 'Hi!']);

// The Tile Layer (very important)
$tileLayer = new \dosamigos\leaflet\layers\TileLayer([
   'urlTemplate' => 'http://otile{s}.mqcdn.com/tiles/1.0.0/map/{z}/{x}/{y}.jpeg',
    'clientOptions' => [
        'attribution' => 'Tiles Courtesy of <a href="http://www.mapquest.com/" target="_blank">MapQuest</a> ' .
        '<img src="http://developer.mapquest.com/content/osm/mq_logo.png">, ' .
        'Map data &copy; <a href="http://openstreetmap.org">OpenStreetMap</a> contributors, <a href="http://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>',
        'subdomains' => ['1', '2', '3', '4'],
    ],
]);

// now our component and we are going to configure it
$leaflet = new \dosamigos\leaflet\LeafLet([
    'center' => $center, // set the center
]);
// Different layers can be added to our map using the `addLayer` function.
$leaflet->addLayer($marker)      // add the marker
        ->addLayer($tileLayer);  // add the tile layer

// finally render the widget
echo \dosamigos\leaflet\widgets\Map::widget(['leafLet' => $leaflet]);

// we could also do
// echo $leaflet->widget();
