I have used the autocomplete of geocode but when I am selecting from the drop down it is giving me the lat and long of the address
I need to check when the lat and long are empty then from the posted address I must get the latitude and longitude
932
function getaddress($lat, $lng) { $url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng=' . trim($lat) . ',' .
Function Usage: php $address = 'Brooklyn, NY, USA'; $address = str_replace(' ', '+', $address); $result = getGeoCode($address); echo 'Latitude: ' . $result['lat'] . ', Longitude: ' . $result['lng']; // produces output // Latitude: 40.6781784, Longitude: -73.9441579 ?>
Suppose you have hidden value for lat and long is mapLat & mapLong and input field name is location then:
<html>
<form>
<input type="hidden" name="mapLat">
<input type="hidden" name="mapLong">
<input type="text" name="location">
<input type="submit" name="submit" value="submit">
</form>
</html>
extract($_POST);
if($mapLat =='' && $mapLong ==''){
// Get lat long from google
$latlong = get_lat_long($location); // create a function with the name "get_lat_long" given as below
$map = explode(',' ,$latlong);
$mapLat = $map[0];
$mapLong = $map[1];
}
// function to get the address
function get_lat_long($address){
$address = str_replace(" ", "+", $address);
$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=$region");
$json = json_decode($json);
$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};
return $lat.','.$long;
}
Using CURL
<?php
$address = "Kathmandu, Nepal";
$url = "http://maps.google.com/maps/api/geocode/json?address=".urlencode($address);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$responseJson = curl_exec($ch);
curl_close($ch);
$response = json_decode($responseJson);
if ($response->status == 'OK') {
$latitude = $response->results[0]->geometry->location->lat;
$longitude = $response->results[0]->geometry->location->lng;
echo 'Latitude: ' . $latitude;
echo '<br />';
echo 'Longitude: ' . $longitude;
} else {
echo $response->status;
var_dump($response);
}
?>
I tried above solutions but none was working then i tried to fix on my own so below is the correct code:
$going=$this->input->post('going');
$address =$going; // Google HQ
$prepAddr = str_replace(' ','+',$address);
$apiKey = 'Add your API Key'; // Google maps now requires an API key.
$geocode=file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?
address='.urlencode($address).'&sensor=false&key='.$apiKey);
//print_r($geocode);
$output= json_decode($geocode);
$latitude = $output->results[0]->geometry->location->lat;
$longitude = $output->results[0]->geometry->location->lng;
