unset session userdata array

Are you talking about having it affect the current user, all logged in users, or a different user who is logged in?

Hi, Thanks for reply I think I have found what best way is.

PHP Code:

public function edit() {

$this->load->model('admin/user/model_user_group');

if ($this->input->server('REQUEST_METHOD') == 'POST') {

$this->model_user_group->editUserGroup($this->uri->segment(4), $this->input->post());

$user_group_query = $this->db->query("SELECT permission FROM " . $this->CI->db->dbprefix . "user_group 
WHERE user_group_id = '" . (int)$this->session->userdata('user_group_id') . "'");

$permissions = unserialize($user_group_query->row('permission'));

$this->session->set_userdata($permissions);

redirect('admin/users_group');
            
}

$this->getForm();

} 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
