For last couple of days I was searching for Google Map Marker with Label functionality then I found the following PHP class in
. I did use this class for both CakePHP and conventional PHP.
This class really help me to integrate the goole map advance features easily in my real estate application. but one feature was missing in the library and that was Label in marker.
I need that label to show the property price in the marker. I start searching for the feature and finally I found it in the following address
http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerwithlabel/1.1.8/docs/examples.html
After 1-2 hours dig down in the script I have decided to integrate this feature in the
PHP Google Maps API.
What I did is here I am trying to share with you...
Added the following variables for the class..
var $marker_with_label = true;
var $marker_label_js = "js/gmap/markerwithlabel.js";
Update the functions as like below
function getHeaderJS() {
if($this->marker_with_label){
$_headerJS .= "";
}
}
function getUtilityFunctions(){
$_script = "";
if(!empty($this->_markers)&& $this->marker_with_label)
$_script .= $this->getCreateMarkerWithLabelJS();
else
$_script .= $this->getCreateMarkerJS();
}
function getAddMarkersJS($map_id = "", $pano= false) {
//defaults
if($map_id == ""){
$map_id = $this->map_id;
}
if($pano==false){
$_prefix = "map";
}else{
$_prefix = "panorama".$this->street_view_dom_id;
}
$_output = '';
foreach($this->_markers as $_marker) {
$iw_html = str_replace('"','\"',str_replace(array("\n", "\r"), "", $_marker['html']));
$_output .= "var point = new google.maps.LatLng(".$_marker['lat'].",".$_marker['lon'].");\n";
if($this->marker_with_label){
$_output .= sprintf('%s.push(createMarkerWithLabel(%s%s, point,"%s","%s", %s, %s, "%s", %s, "%s" ));',
(($pano==true)?$_prefix:"")."markers".$map_id,
$_prefix,
$map_id,

I know its lots of code here. But all you have to do search the functions and replace the function with the above functions...
Now you have to change few more code which you will call by map object.
$gmap = new GoogleMap();
$gmap->addMarkerByCoords($LONGITUDE, $LATITUDE, $title, $html_info_window_data,'your label text');
