I have used above code for google map location from MySQL database.
Above code fetch lat, Lang from MySQL database and dynamically create google map.
When I run above code It gave me error like that:
There are two errors named too much recursion & initMap is not function.
Can anybody help me to sort out it.
Thanks in advance.
You have not defined initMap in your js file. That's why you are getting that error. You probably need to remove the callback part from the google map api script
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap" async defer></script>
To
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY" async defer></script>
Also check if the lat and lon contain valid numeric values in the following statement
var lat = new google.maps.LatLng(addressDetails[1], addressDetails[2]);

This is probably a simple issue but I would appreciate any help
I have loaded a $_SESSION variable from my MVC model , its a multidimensional area of latitude and longitude points in a map. here where I loaded this from
for($i=0; $i<count($markets['results']); $i++) {
.
.
$marketinfo["lat"][$i] = floatval($lat);
$marketinfo["long"][$i] = floatval($lon);
};
$_SESSION['MARKETLOCATION']['LAT'] = $marketinfo["lat"];
$_SESSION['MARKETLOCATION']['LONG'] = $marketinfo["long"];
Then down in the view section I am calling a _template for header with this code
<script type="text/javascript">
function createmap(LatLong) {
var firstpass = true;
for (var i = 0; i < $LatLong.length; i++) {
var lat = $LatLong['LAT'][i];
var lng = $LatLong['LONG'][i];
if (firstpass === true){
var map = new google.maps.Map(document.getElementById('map-canvas'),{
zoom: 10,
center: new google.maps.LatLng($lat[0]+','+$lng[0]),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
firstpass = false;
}
var infowindow = new google.maps.InfoWindow();
marker = new google.maps.Marker({
position: new google.maps.LatLng($lat[i]+','+$lng[i]),
map: map
});
}
window.onload=function(){("createmap($_SESSION['MARKETLOCATION']");};
}
</script>
</head>
<body>
<div class='Mapbox' id = 'map-canvas' ></div>
Problem is the map is not displaying at all. I know that my API key is correct because I tested it before I created this code. So I think it probibaly has to do with Passing the session variable
Again any insight would be appreciated
Javascript and php are two different languages. You need to output your variable from php but you cannot just echo it as $_SESSION['MARKETLOCATION'] is an array.
You should do something like:
var session_variable = <?php echo json_encode($_SESSION['MARKETLOCATION']); ?>;
// now you might have to do some processing on session_variable like parsing it...
// for an example:
var session_object = JSON.parse(session_variable);
window.onload=function(){ createmap(session_object); };
Fix you code:
window.onload=function(){("createmap(<?php echo $_SESSION['MARKETLOCATION'] ?>");};
I am working on this from several hours but no success.
This code is working fine one time and add 100 records on map. Then I want to add more results from db after first 100. how can I do that please guide me. Here is the code.

I am trying to make an array of latitudes and longitudes using cities that I have in a mySQL database. This is what I have so far.

You have a typo: sometimes you use long, at other times lng.
in the code segment:
var marker = new google.maps.Marker({
position: new google.maps.LatLng(data.lat, data.lng),
map: map,
title: data.name
});}
while earlier you use
$lng = $location->lng;
echo "{ lat: ".$lat.", lng: ".$long.", name: ".'"'.$row['city'].", ".$row['state'].'"'."},";
In effect, your echo statement, which should be producing longitudes in your array, is referencing a non-initialized variable, $long. Fix that and you should be good to go. In other words, change
$lng = $location->lng;
to
$long = $location->lng;
(or change your echo statement...)
My earlier answer dealt with the typo. I think there's a fundamental issue with "how to draw maps with the google API". The following code snippet (from google JavaScript API shows an example of using overlays (which is what a marker is):
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP, }
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
title:"Hello World!" });
// To add the marker to the map, call setMap();
marker.setMap(map);
Several of these steps appear to be missing from your code - maybe you didn't show them, or maybe you didn't realize you needed them?
EDIT: even after you posted your full code, I still don't see certain things I would expect.
Here are one thing you can try for sure: call the google API before referencing it: add this line
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=false"> </script>
right below <head>, before your <script>
Fixing just this, and taking out a bunch of "superfluous" (for the purpose of "getting a map with a pin") lines, allowed me to create a simple file that can render a map of New York, NY with one marker on it. The source code can be found at http://www.floris.us/SO/maptest.php.txt . From there, you can add more stuff back in...
Further edit: with the lessons learnt, I made http://www.floris.us/SO/maptestFull.php which has most of the functionality you were looking for (not the DB lookup, which I don't have, obviously). Once again, source code is copied in .php.txt file so you can look at it. Slightly messy (from trying to turn things on/off) - you will have to look closely to see all the changes I made.
I am trying to create a custom google map using Longitudes and Latitudes that I have in my sql database. So I am trying to place these results directly into my jquery code for the geocoder. But it is not working. Does anyone have ANY idea how I could do this?? I have looked up everything possible and can not find an answer. Thank you so much in advance. Here is my code:
<script type='text/javascript'>//<![CDATA[

$name = $row['name'];
$lat = $row['Latitud'];
$lon = $row['Longitude'];
$address = $row['Address1'];
echo $lat;
echo $lon;
?>
var markers = [[<?php echo $lat ?>, <?php echo $lon ?>, '<?php echo $name ?>'], <?php } ?>
];
var infowindow = new google.maps.InfoWindow({});
function initialize() {
geocoder = new google.maps.Geocoder();

Have you checked the output of this script on the markers variable? This seems to have something with the formatted number output.
JavaScript expects numbers in the international format, with periods as the decimal separator: 10.2
In some places the server is configured to use comma as the decimal separators, so the output of your script would return an array of numbers, not a number with decimal places:
[[ 1,00012, 1,45678, 'name' ]]
Also, you have an extra comma at the end of the markers variable declaration, before the closing square bracket ]
i am using google map api to show addresses on map with markers, the problem i am having is, In the marker, i am showing a link to go to the profile page of person which is there in the map, but if there are more than 1 person exists on same address then google group those addresses and doesn't show the link, is there any way we can stop grouping of addresses?
Any help would be appreciated.Thanks

If you put multiple markers for single point, those will always overlap. It will be interesting to see if anyone can help you. I would suggest, when there are more than one people come under same place/marker, put their details/links on the infoWindow. Don't try to show multiple markers for same point. And if you are desperate enough to show multiple markers, then just change size of your marker-icons, so that they are visible to user even-if overlaps.
It is a good thing that google is showing all the relative address together otherwise if it wont, markers will be hidden by each other and you wont be able to see even how many markers are there on one place.
