Autosolucionado en 5 min, ayer estaba muy espeso... aqui dejo una de las formas de hacerlo ...
Código PHP:
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?sensor=true">
</script>
<script type="text/javascript">
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
codeAddress("Barcelona");
codeAddress("Tarragona");
codeAddress("Lleida");
codeAddress("Girona");
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
function codeAddress(address) {
if (geocoder) {
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<div id="map_canvas" style="width:590px; height:450px"></div>
Solo falta meterle el bucle, pero a modo de prueba ya tira
Saludos
