问题:

I'm starting to know PHP and JavaScript, mixing them in HTML and using Google Maps API (version 3).

I figured how to 'put' various markers but the console will throw me an error:

" Uncaught InvalidValueError: setCenter: not a LatLng or LatLngLiteral object ".

I think it's because the var created in the loop is not exactly the object needed but instead a string, though this confuses me, I don't know if I'm right. I'd appreciate it a lot if anyone could set me in the right path.

Thanks in advance.

This is my code: (By the way, the array I'm looping is an array with an array with an array, here's some of it. It follows the pattern, there are in total 6 'places'):

$locations = array(         array(             'Location' => array(                 'Title'=>'Place',                 'Description'=>'Some Place',                 'Image'=>'pin1.png',                 'Latitude'=>'20.681775',                 'Longitude'=>'-103.351479'             )         ),…

(It continues…).

And here's a screenshot of that var assigning part: " http://cl.ly/image/1d3e2J360t3y "

It is also worth noting that Google Maps v3 doesn't appear to sanitize the data values for setting markers. This seems to have changed in the last few weeks, because previously I was passing in icon height as a string for google's MarkerImage function (it is coming from JSON). But that suddenly broke because it wasn't a "number".

Obviously the solution is to pass in a number, or wrap your data in parseInt() or parseFloat() so that the API gets a number or float. Google "should" be sanitizing it's data but it isn't.

var custom_icon = new google.maps.MarkerImage(     icon_path,     new google.maps.Size(         parseInt(icon_options.width),         parseInt(icon_options.height)     ),     new google.maps.Point(         parseFloat(icon_options.origin_x),         parseFloat(icon_options.origin_y)     ),     new google.maps.Point(         parseFloat(icon_options.anchor_x),         parseFloat(icon_options.anchor_y)     ) );

You are initializing mapOptions in wrong way.

Initialize it in following way..

var mapOptions = {           center: new google.maps.LatLng(20.68177501, -103.3514794),           zoom: 15,           mapTypeId: google.maps.MapTypeId.ROADMAP         };

Instead of...

var mapOptions = {           center: (20.68177501, -103.3514794), //this is not correct           zoom: 15,           mapTypeId: google.maps.MapTypeId.ROADMAP         };

Following is corrected code...

<!DOCTYPE html> <html>   <head>     <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />     <style type="text/css">       html { height: 100% }       body { height: 100%; margin: 0; padding: 0 }       #map-canvas { height: 100% }     </style>              <script type="text/javascript"           src="https://maps.googleapis.com/maps/api/js?AIzaSyBVfO8LckdOHAot1a8rZW0bmJIoWO2A3os=API_KEY&sensor=true">         </script>         <script type="text/javascript">       function initialize() {         var mapOptions = {           center: new google.maps.LatLng(20.68177501, -103.3514794),           zoom: 15,           mapTypeId: google.maps.MapTypeId.ROADMAP         };         var map = new google.maps.Map(document.getElementById("map-canvas"),             mapOptions);          // To add the marker to the map, use the 'map' property         <?php $i = 0; ?>         <?php foreach($locations as $key => $value): ?>                 <?php foreach($value as $key => $value): ?>                     <?php foreach($value as $key => $value): ?>                         <?php if($key == "Latitude"): ?>                             <?php $myLatLng = "$value, "; endif;?>                         <?php if($key == "Longitude"): ?>                             <?php $myLatLng .="$value"; ?>          var myLatlng<?php echo $i; ?> = new google.maps.LatLng(<?php echo $myLatLng; ?>);         var marker<?php echo $i; ?> = new google.maps.Marker({         position: (myLatlng<?php echo $i; ?>),         title:"Hello World!"         });         marker<?php echo $i; ?>.setMap(map);                               <?php $i++; ?>                         <?php endif; ?>                     <?php endforeach; ?>                 <?php endforeach; ?>         <?php endforeach; ?>       }       google.maps.event.addDomListener(window, 'load', initialize);     </script>     </head>   <body>     <div id="map-canvas"/>   </body> </html>

Try deleting the line

<script type="application/javascript" src="google_maps/google_maps.js"></script>

and keep

<script type="application/javascript" src="http://maps.googleapis.com/maps/api/js?key=your-api-key"></script>
