在数据库中插入纬度经度

I am currently working on a code where when the user enters location he will get latitude n longitude however i need to add both lat and long to database. Client side the code is working the html file is given below.

How do I transfer these values for server side in php and add them to database.

    <!DOCTYPE html>
    <html>
    <head>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
    <meta charset="UTF-8">
    <title>maps</title>
     <style>
     #map_canvas { width:400px; height:450px; }
      </style>
     <script type="text/javascript" src="http://maps.google.com/maps/api/js?                   sensor=false">
     </script>
     <script type="text/javascript">

      var geocoder;
      var map;
      var lat;
      var lng;

       function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-30.070, -51.190);
var myOptions = {
    zoom: 9,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}

    function codeAddress() {
var address = document.getElementById("address").value;
geocoder.geocode( { 'address': address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
        map.setCenter(results[0].geometry.location);
        var marker = new google.maps.Marker;
        document.getElementById('lat').value = results[0].geometry.location.lat();
        document.getElementById('lng').value = results[0].geometry.location.lng();


    } else {
        alert("Geocode was not successful for the following reason: " + status);
    }
});
  }



   </script>
    </head>

    <body onload="initialize()">
    <form action="map2.php" method="get">

 <div id="map_canvas"></div>
 <div>
    <input id="address" type="textbox" value="">
    <input type="button" value="Localizar!" onclick="codeAddress()"><br>
    Latitude: <input type="text" id="lat"><br>
    Longitude: <input type="text" id="lng"><br>
 </div>

    You can do this easily using jquery( no page load or form submit needed)-

    if (status == google.maps.GeocoderStatus.OK) {
    map.setCenter(results[0].geometry.location);
    var marker = new google.maps.Marker;
    document.getElementById('lat').value = results[0].geometry.location.lat();
    document.getElementById('lng').value = results[0].geometry.location.lng();


   // add this
    var latt=results[0].geometry.location.lat();
    var lngg=results[0].geometry.location.lng();
    $.ajax({
        url: "your-php-code-url-to-save-in-database",
        dataType: 'json',
        type: 'POST',
        data:{ lat: lat, lng: lngg }
        success: function(data)
        {                
           //check here whether inserted or not 
        }
   });


 }

    and in the php file :

      <?php
    // file name: your-php-code-url-to-save-in-database.php
   $lat=$_POST['lat'];
   $lng=$_POST['lng'];

   // write your insert query here to save $lat and $lng 


  ?>

    to know more and download Jquery visit :http://jquery.com/download/

    Another way is without Jquery( Page will redirect to map2.php):

    <div id="map_canvas"></div>
<form action="map2.php" method="get">
   <div>
    <input id="address" type="textbox" value="">
    <input type="button" value="Localizar!" onclick="codeAddress()"><br>
    Latitude: <input name="lat" type="text" id="lat"><br>
    Longitude: <input name="lng" type="text" id="lng"><br>
   </div>
</form>

    and in your map2.php write-

     <?php

     // file name: map2.php

   $lat=$_GET['lat'];
   $lng=$_GET['lng'];

   // write your insert query here to save $lat and $lng 
   //get your mysql db connection ready

    $sql="insert into table_name (latitude, longitude) values('".$lat."','".$lng.")";
    $command=mysql_query($sql);

    // close databse connection  and everythig is done then redict to any page.
    //check your database table to see the inserted value

  ?>

    In your form method I would suggest to use POST instead of GET .If you made this change then in your map2.php just change GET to POST only. To know the reason of using POST visit Link 1 and Link 2
