What error are you getting? –  James Jenkins Jun 14 at 15:36
 
you must start a session on each page where you actually want to access session values. –  Ghazanfar Mir Jun 14 at 15:48

add all the notifications to an array you instantiate prior to the foreach then add the array to session.

Also note if your using the standard codeigniter session there is a 4k limit on its size so this may not be the best approach.

Also, this is working on the assumption that your session class has been properly initialized...

I did my best to clean up your code.

function get_user_notifications($userID){
    $this->db->select()->from('messages')->where('receiverID',$userID);   
    $query = $this->db->get();
    $all_notifications = array();
    if($query->num_rows()>0)
    {
          foreach($query->result() as $rows)
          {
           //add all data to session
               $all_notification[]=$rows->notification;
               $messageID=$rows->messageID;     

          }
          $this->session->set_userdata('mynotifications',$all_notification);
    }

Try this,

function get_user_notifications($userID){
    $this->db->select()->from('messages')->where('receiverID',$userID);   
    $query = $this->db->get();
    $notification='';
    if($query->num_rows()>0)
    {
        foreach($query->result() as $rows)
        {
            //add all data to session
            $notification.=$rows->notification.',';
            $messageID=$rows->messageID;
            // $rows->messageID =>,
        }
    }
    $this->session->set_userdata('mynotifications',$notification);
}
