       $data['user'] = $this->m_user->getRows($userID);
        //load the view
      if( $data['user']['profile_pic'] == null && $data['user']['profile_pic']!= null)
      {

        $data['user'] = $this->m_user->getRows($userID);
        //load the view
      if($user->profile_pic==null)
      {     
            $url = base_url().'user/profilepicture/';
