Examples
All samples are available in the sfEasyGMapPlugin module of the plugin
Sample 1
Add some markers on a map, using longitudes and latitudes
In the action:
$this->gMap = new GMap();
$this->gMap->addMarker(new GMapMarker(51.245475,6.821373));
$this->gMap->addMarker(new GMapMarker(46.262248,6.115969));
In the template:
<?php use_helper('Javascript','GMap') ?>
<?php include_map($gMap,array('width'=>'512px','height'=>'400px')); ?>
<!-- Javascript included at the bottom of the page -->
<?php include_map_javascript($gMap); ?>
Sample 2
Geocode some addresses and open an info window if the user clicks on a marker
In the action:
$this->gMap = new GMap();
// some places in the world
$addresses = array(
'Graf-Recke-Strasse 220 - 40237 Düsseldorf',
'Avenue des sports 01210 FERNEY-VOLTAIRE - FRANCE',
'44 boulevard Saint-Michel, Paris',
'Route Saclay 91120 Palaiseau',
'Rämistrasse 101, Zürich'
);
foreach ($addresses as $address)
{
$geocoded_address = $this->gMap->geocode($address);
$gMapMarker = new GMapMarker($geocoded_address->getLat(),$geocoded_address->getLng());
$gMapMarker->addHtmlInfoWindow('<b>Address:</b><br />'.$address);
$this->gMap->addMarker($gMapMarker);
}
In the template:
<?php use_helper('Javascript','GMap') ?>
<?php include_map($gMap,array('width'=>'512px','height'=>'400px')); ?>
<!-- Javascript included at the bottom of the page -->
<?php include_map_javascript($gMap); ?>
Sample 3
change the map center location and the zoom level
change the zoom and movement controls used
store the markers' javascript objects in a javascript array
use a custom icon for the markers
bind event listeners to the markers linked to custom javascript functions
add custom property to the markers' javascript objects
In the action:
// parameters: zoom level, lat, lng, options
$this->gMap = new GMap(4,45,8,array('control'=>'new google.maps.SmallMapControl()'));
// some places in the world
$coordinates = array(
array(51.245475,6.821373),
array(46.262248,6.115969),
array(48.848959,2.341577),
array(48.718952,2.219180),
array(47.376420,8.547995)
);
// adds a variable "markers" defined on the global level
$this->gMap->addGlobalVariable('markers','new Array()');
// creates a custom icon for markers
$gMapIcon = new GMapIcon(
'nice_icon',
'/sfEasyGMapPlugin/images/nice_icon.png',
array(
'width'=>18,
'height'=>25,
'info_window_anchor_x'=>9,
'info_window_anchor_y'=>25
)
);
// creates two custom event listeners
$gMapEvent1 = new GMapEvent(
'mouseover',
"document.getElementById('console_div').innerHTML = 'Mouse over marker number '+this.num;"
);
$gMapEvent2 = new GMapEvent(
'mouseout',
"document.getElementById('console_div').innerHTML = '';"
);
foreach ($coordinates as $key=>$coordinate)
{
// parameters: lat, lng, marker's javascript object's name, icon object
$gMapMarker = new GMapMarker($coordinate[0],$coordinate[1],'markers['.$key.']',$gMapIcon);
$gMapMarker->addHtmlInfoWindow('<b>Coordinates:</b><br />'.implode(', ',$coordinate));
// will add a custom property to the marker's javascript object
$gMapMarker->setCustomProperty('num',$key);
// binds the event listeners to the marker
$gMapMarker->addEvent($gMapEvent1);
$gMapMarker->addEvent($gMapEvent2);
$this->gMap->addMarker($gMapMarker);
}
In the template:
<?php use_helper('Javascript','GMap') ?>
<?php include_map($gMap,array('width'=>'512px','height'=>'400px')); ?>
Search on the map:
<?php include_search_location_form() ?>
<br />
<br />
<div id="console_div" style="font-size:large"></div>
<!-- Javascript included at the bottom of the page -->
<?php include_map_javascript($gMap); ?>
TODO
- make the javascript more compact
- correct javascript files that suppose that the map's javascript object is called 'map'
- add support for EncodedLines
- add support for custom zoom and move controls
