I am very new in HTML5 area, I am trying to make a program that will fetch the data from mysql with PHP and use geocode to transform from address to Latlng. it is a LBS program, and I was trying for 2 weeks, my question is I cannot put markers into the Google MAP, I did the locator corrected and map is loaded, but the marker cannot land on map, please help!! thank you, and I am really appreciate your help. if this code has any mistake or problem please give me generous advice, I am very new in this area, and I am trying to learn more in HTML5 Javascript, thank you and I am very appreciate your advice!!!
my code is here:
'enter code here`<?php
require_once 'Common/system_start.php';
$sql="select addr from tab_mem order by sn desc ";
$result= mysql_query($sql);
$data=mysql_fetch_assoc($result);
$row=mysql_num_rows($result);
$n = array();
for($i=0;$i<$rows;$i++)
{
$data=mysql_fetch_row($result);
$n[] = $data[0];
}
echo '<script type="text/javascript">';
echo var n = new Array("', join($n,'","'), '");';
echo '</script>';
?>

Your code doesn't look well-formed. You have the "addMarker" function defined inside your "for" loop. Also, it's not getting called anywhere.
Take a look at the sample code Google provides for working with markers and overlays and try to emulate it. The sample only uses one marker, but you can simply iterate through your results. You've got the right intentions by adding your Marker objects to an array, and setting your map object to the map property of the Marker, but you will need to format/restructure your code first or it will not work.
Sample code:

I currently have realtime analytics php api. It has this entity named $resulting. If I do print_r($resulting); it returns for example (if only 1 user is online):
Array ( [0] => Array ( [0] => Arnhem [1] => 5.898730 [2] => 51.985104 [3] => Chrome [4] => DESKTOP [5] => / [6] => 1 ) )
Now, later on in the same file, I have the google maps javascript api.
It has markers in the form of:
var markers = [
{
coords:{lat:52.0907,lng:5.1214},
content:'<h1>Utrecht</h1>'
},
{
coords:{lat:52.0907,lng:5},
content:'<h1>Links</h1>'
},
{
coords:{lat:52.0907,lng:6},
content:'<h1>Rechts</h1>'
}
];
As placeholder for now.
What I want to do, is have in the coords: section have the lat: and lng: be the appropriate values from $resulting.
Also, I want to have as many markers as there are users online.
Now, I have tried everything I can think of, but I can't get it to work.
I have tried for example:
const results = <? php echo json_encode($resulting); ?>;
let markers = [];
for(let i = 0; i < results.length; i++) {
markers[i] = {
coords: {
lat: results[1],
lng: results[2]
}
};
}
but then the maps won't load anymore.
I have tried looping, foreach, trying to get the lat: and lng: to update with the values returned by $resulting, but whatever I do it simply won't work.
Can anybody help me and get this working?
Thanks.

Also, what the json_encode returns with 2 users online:
[["Arnhem","5.898730","51.985104","Chrome","DESKTOP","\/","1"],["Eindhoven","5.469722","51.441643","Chrome","MOBILE","\/","1"]]
You should also assign the map object to the marker (assuming your map object is named map )
for(let i = 0; i < results.length; i++) {
markers[i] = {
coords: {
lat: results[1],
lng: results[2]
},
map: map
};
}
To help you identify the issue, it would be useful to see the rest of your javascript code for the map api, as well as the array when there's more than one user after running it though json_encode(). That said, try the following:
const results = <? php echo json_encode($resulting); ?>;
for(let i = 0; i < results.length; i++) {
let marker = new google.maps.Marker({
position: {lat: results[1], lng: results[2]},
content: '<h1>' + results[0] + </h1>,
map: map
});
}
Edit:
I don't have Composer installed in the directory I tested your code in, and I haven't worked much with the Google realtime API, but the following javascript will work given the output you listed for $resulting. You'll have to tweak things depending on where your custom icons are coming from, but that should be pretty straightforward.

I'm using google maps API to make a map that retrieves data from the database and shows the corresponding markers on the map. I did this by following these instructions: https://developers.google.com/maps/articles/phpsqlajax_v3
What I'm now trying to do is create a page (called add_marker.php) that has a draggable marker so that the user can then add the new marker to the database based on the coordinates. I want to be able to see the other markers when I'm on this page. I also include the map code in all the pages so I don't want it to change drastically just for this page, so my approach is the following: Make the draggable marker invisible in all the pages except for the add_marker page by setting the icon setting to an empty string " ". Now the problem is, I can't change the icon's image so I can see it in the particular page I want it visible. I've searched quite a bit here in stackoverflow and found some solution, but none of these worked.
The error that I get is: add_marker.php:9 Uncaught Reference Error: drag_marker is not defined
(Even though I've made the marker variable global)
The code is the following:
map_code.php (This is the page that I made with the help of the link and is almost identical to that code except for some variable names. It's included in the files that use the map)
Any help would be greatly appreciated

You are attempting to use the drag_marker variable before it is defined (and probably also before it is initialized, look at the HTML/JavaScript rendered in the browser).
To deal with the timing issue, try:
google.maps.event.addDomListener(window, 'load', function() {
drag_marker.setIcon("http://maps.google.com/mapfiles/ms/icons/red-dot.png");
}):
I have just added bing maps and API to my in development site however I am needing some help understanding how to have my code accept live updating lat and long coordinates and have my map update the marker in regards to these values.
Currently this is what I have but part of the code was designed for google maps which I replaced the words google with Microsoft hoping for the best.
Please be gentle I am new to coding

Engineer was right, you need to use $.getJSON method, $.parseJSON takes a JSON string, it doesn't load an external file.
getJSON: http://api.jquery.com/jQuery.getJSON/
parseJSON: http://api.jquery.com/jQuery.parseJSON/
I put your code in a jsFiddle and it is working with getJSON and an alternative test JSON file (you didn't provide the original test.json you're using).
$.getJSON('test.json', function(data) {
$.each(data.markers, function(i, obj) {
var latLng = new google.maps.LatLng(obj.lat,obj.lng);
var content = obj.id + ':' + obj.lat + ',' + obj.lng;
markMap(latLng, content);
});
});
http://jsfiddle.net/WYfjv/
If your code is not working maybe your JSON is not well formatted (try JSONLINT to test it). Also, if you are already improving, I would advise to use a normal for loop rather than $.each :)
i've been dealing with this couple of hours and i still cant figure how to do it.
my objective is to display only one marker when searching addresses close to each other.
below you have the code i use in my html in order to search for addresses, note - i'm developing a windows application that does such, in which case you might find some missing stuff to do actions by clicking buttons since this is done via .NET windows application

You can add a small bit of code to the beginning of your Geocode function that will remove the previous marker before setting a new one. Try this:
function geocode(address){
if (marker) {
marker.setMap(null);
}
geocoder.geocode({ 'address': (address ? address : "Miami Beach, Florida")}, function (results, status) {
Create only one marker as a global variable and change its position as needed. Like that you also save memory because you're not creating a new marker object on each request:
