Script to move lat & lang in your Table

Let's take this topic a step higher.

I came across a script gives you the latitude and longitude values on an address

<?php
// Fixed addresses from the example, they work!
//$address = "1600 Pennsylvania Ave NW Washington DC 20500";
//$address = str_replace(" ", "+", $address);
//$region = "USA";

$address = $values['Adres'];
 $city = $value['Woonplaats'];
 $combinedAddress = $address . ',' . $city;
$region = "Europe";

$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region");
$json = json_decode($json);

$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};
echo $lat."
".$long;

This works.

Now I like to take the values from 'Address' and 'City' from my Table copied into this script and then the value of $lat en $log should be added to the fields 'Latitude' and 'Longitude'. when a new client is added to my database.

I think this needs to be done in 'Before record added' in the Add Page.
