I have a clunky-architecture question :)
I have 1 php script. The script performs a database query for longitude/latitude from the database, and gets that data. Then what I need it to do is call JavaScript function which places a marker on the spot of the lat/lng.
Is that possible to accomplish? How is such a thing best done?
Thanks, Alex
A simplest way to pass value from php to javascript is to simply create a variable inside script tag on your page.
<script type="text/javascript">
var lat = <?php echo $phpLat;?>;
var lng = <?php echo $phpLng;?>;
...
</script>
Then, where you initialize the map, you can also create a marker. Something like this
var point = new google.maps.LatLng(lat, lng);
var marker = new google.maps.Marker({
position: point,
title: 'test'
});
marker.setMap(map);
You can check Google Maps Javascript API documentation for more information.
You could use the jQuery library to do this by using the ajax function.
this way you use the javascript to run the PHP this is the easiest way.
$.ajax({
url: "your-php-file.php",
success: function(result){
//the return will be in the result variable
}
});
it's up to you how you return it from php but you could return it as an array, comma delimited string, etc...
