  $default_category = $db->loadResult();
  }
  
  $query = 'SELECT * FROM #__b2portfolio_category where id='.$default_category;
  $db->setQuery( $query );
  $cat_data =$this->_db->loadObject($query);
  	
  return $cat_data;
  }
  
  function click() {
  $db =& JFactory::getDBO();
  $date =& JFactory::getDate();
  $trackDate = $date->toFormat( '%Y-%m-%d' );
