This module provides integration with Leaflet map scripting library, http://leaflet.cloudmade.com. To use, you must download the leaflet library from: http://leaflet.cloudmade.com/download.html Alternativelly, you can build the library from source. If so, follow the instructions at: http://leafletjs.com/download.html#leaflet-source-code In its current state, maps can be rendered via the included field formatter for Geofield or by using the API directly. Installation ------------ 1. Normal Drupal module installation 2. Download the Leaflet library from http://leafletjs.com/. Leaflet 0.6 or higher is recommended. Extract it to your drupal root /sites/all/libraries/leaflet. The file 'leaflet.js' must be found at /sites/all/libraries/leaflet/leaflet.js. All other files and folder(s) that come with the library are also needed there. 3. Enable leaflet_views for using Views and Leaflet (see below), or use the display formatters for fields display. API Usage --------- Building a map is as simple as calling a single method, leaflet_build_map(), which takes 3 parameters. $map (array) An associative array defining a map. See hook_leaflet_map_info(). The module defines a default map with a OpenStreet Maps base layer. $features (array) This is the tricky part. This is an associative array of all the features you want to plot on the map. A feature can be a point, linestring, polygon, multilinestring, multipolygon, or json object. Additionally, features can be grouped into layer groups so they can be controlled together, http://leaflet.cloudmade.com/reference.html#layergroup. A feature will look something like: $features = array( array( 'type' => 'point', 'lat' => 12.32, 'lon' => 123.45, 'icon' => array( 'iconUrl' => 'sites/default/files/mymarker.png' ), 'popup' => l($node->title, 'node/' . $node->nid), 'leaflet_id' => 'some unique ID' ), array( 'type' => 'linestring', 'points' => array( 0 => array('lat' => 13.24, 'lon' => 123.2), 1 => array('lat' => 13.24, 'lon' => 123.2), 2 => array('lat' => 13.24, 'lon' => 123.2), 3 => array('lat' => 13.24, 'lon' => 123.2), 4 => array('lat' => 13.24, 'lon' => 123.2), ), 'popup' => l($node->title, 'node/' . $node->nid), 'leaflet_id' => 'some unique ID' ), array( 'type' => 'json', 'json' => [JSON OBJECT], 'properties' = array( 'style' => [style settings], 'leaflet_id' => 'some unique ID' ) ) ); $height (string) Height of the map expressed in pixels. Append 'px'. Default: '400px'. Views integration ----------------- To render a map using Views, enable the module leaflet_views. You need to add at least one geofield to the Fields list, and select the Leaflet Map style in Format. In the settings of the style, select the geofield as the Data Source and select a field for Title and Description (which will be rendered in the popup). As a more powerful alternative, you can use node view modes to be rendered in the popup. In the Description field, select "<entire node>" and then select a View mode.
