 Samuel Bistak - 2015-12-18 17:54:22 Dear fellas,
I'm using this class is very good but i have one problem. How i can get current location Lat. and Long. when i first load map?
 Vagharshak Tozalakyan - 2015-12-19 13:44:48 - In reply to message 1 from Samuel BistakCurrently there is no JS callback for geolocation, but you can use the JS timer to detect when coordinates available. Something like this:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Maps Test</title>
<script>
function mbOnAfterInit(map) {
var timer = window.setInterval(function() {
if (geoMarker.getPosition()) {
alert(geoMarker.getPosition());
clearInterval(timer);
}
}, 1000);
}
</script>
</head>
<body>
<?php
require_once 'class.MapBuilder.php';
$map = new MapBuilder();
$map->overrideCenterByGeo(true);
$map->addGeoMarker();
$map->show();
?>
</body>
</html>
Samuel Bistak - 2015-12-19 13:54:54 - In reply to message 2 from Vagharshak TozalakyanThanks a lot. But i need to set variable in PHP for current Lat and Long coordinate to work with them that's why alert is not very helpful. Don't you have any idea how to manage that?
Samuel Bistak - 2015-12-19 14:12:27 - In reply to message 3 from Samuel BistakSorry never mind. I got it now with $map->GetcenterLat / Lng;
Thx
Vagharshak Tozalakyan - 2015-12-19 14:51:47 - In reply to message 4 from Samuel BistakThe latest version of library includes corresponding JS callback:
<script>
function mbOnAfterLocationDetected(lat, lng) {
alert(lat + ' ' + lng);
}
</script>
It is impossible to get client coordinates directly in PHP simply because they are CLIENT coordinates. However, you can pass them back via AJAX call:
<script>
function mbOnAfterLocationDetected(lat, lng) {
$.post('myscript.php', {lat: lat, lng: lng}, function(response) {
});
}
</script>
Samuel Bistak - 2015-12-19 15:02:00 - In reply to message 5 from Vagharshak TozalakyanI used $map->$map->getCenterLat(); after <script>...</script> and it worked for now...
Vagharshak Tozalakyan - 2015-12-19 16:00:03 - In reply to message 6 from Samuel BistakThe getCenterLat() and getCenterLng() methods are just return what was set by setCenter(), nothing more... So they cannot be used to detect client location coordinates.
Samuel Bistak - 2015-12-19 17:25:11 - In reply to message 7 from Vagharshak TozalakyanAah ok sorry my bad :)...
Please can you explain me more how can i get the values from current position Lat and Lng via Ajax?
Vagharshak Tozalakyan - 2015-12-19 18:31:39 - In reply to message 1 from Samuel BistakJust be sure to use the latest version of the class that support mbOnAfterLocationDetected() callback.
<?php
// myscript.php
if (isset($_POST['lat']) && isset($_POST['lng'])) {
$lat = floatval($_POST['lat']);
$lng = floatval($_POST['lng']);
// do something...
die();
}
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Maps Test</title>
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script>
function mbOnAfterLocationDetected(lat, lng) {
$.post("myscript.php", {lat: lat, lng: lng});
}

<body>
<?php

$map->overrideCenterByGeo(true);

</html>
Samuel Bistak - 2015-12-19 19:20:17 - In reply to message 9 from Vagharshak TozalakyanThanks a lot. I have updated class but somthing is wrong.
When i want make var_dump($lat); is still empty but AJAX is making request and i can find coordinates in network tab they are there but i cannot use them in document. cuz $_POST['lat'] is empty... i don't know why...
if (isset($_POST['lat']) && isset($_POST['lng'])) {
$lat = floatval($_POST['lat']);
$lng = floatval($_POST['lng']);
var_dump($lng);
die();
}
else {
echo 'empty';
}
?>
