Here's what I've done: (I use the jmaps plugin for jquery FYI)
In my template view I have code like this in the head of the document: (inside my script tag)
Code:
<?php if ( $map_display == 'city' || $map_display == 'property') : ?>
var url = '/map/coordinates.php';
$.get(url, {'address': '<?=$address?>', 'key': '<?=$this->config->item('google_map_key')?>'}, function(data) {
var json = eval("(" + data + ")");
if (json.coordinates.lat != 0) {
$('#map').jmap({ center: [json.coordinates.lat, json.coordinates.lng], zoom: <?=$zoom_lvl?> });
}
});
<?php else : ?>
var url = '/map/coordinates.php';
var key = '<?=$this->config->item('google_map_key')?>';
$('#map').jmap({ zoom: <?=$zoom_lvl?> });
<?php endif; ?>
The code that the url variable refers to is: (this is where the geocaching is done)
Code:
<?php
// this is a very unelegant method of getting map markers
// but it works for the moment - until more than 10000 happen in one day
header('Cache-Control: no-cache');
header('Pragma: no-cache');
// build the google url to ping for coordinates
$address = str_replace(' ', '+', $_GET['address']);
$key = $_GET['key'];
$url="http://maps.google.com/maps/geo?q=" . str_replace(" ", "+", $address) . "&output=csv&key;=" . $key;
// send the request
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1);
$remote_content = curl_exec($curl);
curl_close ($curl);
// scrape the returned csv
$coordinates = split(',', $remote_content);
$lat = $coordinates[2];
$lng = $coordinates[3];
// return some json
$data = '
{"coordinates":
{
"lat": "' . $lat . '",
"lng": "' . $lng . '",
"address": "' . str_replace('+', ' ', $address) . '"
}
}';
echo $data;
?>
As you can see this is just a basic PHP file, not a controller or anything. This is also an old solution, but it works well. If you're gather the same addresses repeatedly it'd be a good idea to database the coordinates to save your google requests from being too numerous.
Hope this helps!
