Link to location on google map
I have a page which have开发者_如何学编程 lots of addresses. I want to have 'locate' link beside all the addresses which will take us to another page and show the location on google map. Since i am a total noob when it comes to google maps, can anyone help me how to do this? I definitely dont want to create separate pages for each address location. Any sleek/efficient method?
First grab the latitude and longitude from some geocoding service like Google.
$zoom = 15;
$type = 'ROADMAP';
$data = file_get_contents("http://maps.google.com/maps/geo?output=csv&q=".urlencode($address));
$arr = explode(",", $data);
if (count($arr)>=4) {
if ($arr[0]==200) {
$lat = $arr[2];
$long = $arr[3];
} else {
throw new Exception('Lookup failed');
}
} else {
throw new Exception('Lookup failed');
}
Then return a page which uses the Google Maps API.
<html style="height: 100%">
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title><?php echo $lat; ?>, <?php echo $long; ?></title>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
function initialize() {
var myLatlng = new google.maps.LatLng(<?php echo $lat; ?>,<?php echo $long; ?>);
var myOptions = {
zoom: <?php echo $zoom; ?>,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.<?php echo $type; ?>
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"<?php echo $lat; ?>, <?php echo $long; ?>"
});
}
</script>
</head>
<body onload="initialize()" style="height: 100%; margin: 0px; padding: 0px">
<div id="map_canvas" style="height:100%;"></div>
</body>
</html>
