The more I use codeigniter the better I like it - I've already changed some sites from Drupal to CI.

Anyway a small problem, that I've mentioned in the forum

Using Ion 2

Small problem, first the function $this->ion_auth->is_group($group) should be in_group().
I think I remember seeing this elsewhere. However a problem exists if you pass an array of groups.

Currently is_group returns in_array($check_group, $groups) which won’t work if check_group is an array.

Solution:
application/libraries/Icon_auth.php

Add condition to check if $check_groups is an array and if it is then walk through the array checking for a match.

public function in_group($check_group) { 
 $this->ci->ion_auth_model->trigger_events('is_group'); 
 $users_groups = $this->ci->ion_auth_model->get_users_groups(); 
 $groups = array(); 
 foreach ($users_groups as $group) { 
 $groups[] = $group->name; 
 }  
 $permission = false; 
 if(is_array($check_group)) { 
foreach($check_group $key => $value){ 
 if(in_array($value, $groups)) {  
 $permission = true;  
 }  
 }  
 } else {  
 if(in_array($check_group, $groups)) { 
 $permission = true; 
 }
 } 
 return $permission; 
}
