How to call joomdle web service functions in my own service

hi antonio, iv'e seen the code and if i specify 'name' it create the query with "order by firstname lastnale"... However i've also tryed passing 'firstname' and doesn't work... this is the code of mentioned method in "moodle/auth/joomdle/auth.php"

function get_moodle_users ($limitstart, $limit, $order, $order_dir, $search )
{
global $CFG, $DB;

/* Don't show admins and guests */
$admins = get_admins();
foreach ($admins as $admin)
{
$a[] = $admin->id;
}
$a[] = 1; //Guest user
$userlist = "'".implode("','", $a)."'";

if ($limit)
$limit_c = " LIMIT $limitstart, $limit";

// kludge for ordering by name
if ($order == 'name')
$order = 'firstname, lastname';

if ($order != "")
$order_c = " ORDER BY $order $order_dir";
else $order_c = "";

if ($search)
$users = $DB->get_records_sql("SELECT id, username, email, firstname, lastname ,auth
FROM {$CFG->prefix}user
WHERE deleted = 0
AND((username like '%$search%') OR (email like '%$search%') OR (firstname like '%$search%') OR (lastname like '%$search%'))
$order_c
$limit_c");
else
$users = $DB->get_records_sql("SELECT id, username, email, firstname, lastname ,auth
FROM {$CFG->prefix}user
WHERE deleted = 0
$order_c
$limit_c");

$i = 0;
foreach ($users as $user)
{
$u[$i] = get_object_vars ($user);
if (in_array ($user->id, $a))
$u[$i] = '1';
else $u[$i] = '0';

$u[$i] = $user->firstname . ' ' . $user->lastname;

$i++;
}
return $u;
}

You are right, I had forgot about that.

I don't know why it is not working...it is not liking some of your params, but I don't know why

i don't know how now it works!... usign

$request = xmlrpc_encode_request("joomdle_get_moodle_users", array(0, 20, '', '', $search), array ('encoding' => 'utf8'));

thanks for your support!
