Reset to default 5You 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./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.")";
$mand=mysql_query($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
