Teseo that was an erro in typing. however, after playing around with it, I found this.$user = '';
$user_id = '';
if(!OC_ADMIN){
$user = osc_user();
$user_id = $user['pk_i_id'];//gets the current user id
}else{
$user = Params::getParam('id');
$user_id = $user['0'];
}
it works perfectly..any suggestion???
