            foreach($query->result() as $rows)
        {
          //add all data to session

            // $rows->messageID =>,



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


     }

you must start a session on each page where you actually want to access session values. — Ghazanfar Mir

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);
}
