Hi,
sorry but we does not have a piece of code to make this already done.

Do you load Joomla environment in your batch file? I ask you this because Easy Profile have own libraries to do this.

Hi,
have you tried to assign the value with JSN user object (http://docs.easy-profile.com/index.php/article/jsnuser-object)?

For example:
I assume gmap have alias like "address"

require_once(JPATH_SITE.'/components/com_jsn/helpers/helper.php');

$user=JsnHelper::getUser($user_id);

$user->setValue('address',$town . ' ' . $country . ' ' . $post_code);

$user->save();

Many thanks.

Here is the code I ended up with that works and may be of use to others:

require_once(JPATH_SITE.'/components/com_jsn/helpers/helper.php');
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('id')
->from('#__jsn_users')
->where('location is NULL')
->order('id');
$db->setQuery($query);
$user_ids = $db->loadColumn();
foreach ($user_ids as $user_id)
 {
 $user=JsnHelper::getUser($user_id);
 $user->setValue('name_of_gmap_field',$user->customfield_1 . ' ' . $user->customfield_2 . ' ' $user_>customfield_3);
 $user->save();
 }

Sorry, i forgot to change one of the field names:

require_once(JPATH_SITE.'/components/com_jsn/helpers/helper.php');
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('id')
->from('#__jsn_users')
->where('name_of_gmap_field is NULL')
->order('id');
$db->setQuery($query);
$user_ids = $db->loadColumn();
foreach ($user_ids as $user_id)
{
$user=JsnHelper::getUser($user_id);
$user->setValue('name_of_gmap_field',$user->customfield_1 . ' ' . $user->customfield_2 . ' ' $user_>customfield_3);
$user->save();
}
