Now, we try to write code for inserting comment. For this task, we add case "comment" at hello.php. Follow this steps:

1. Open "hello.php" within joomla/administrator. Insert following bold code:

   
   switch( $task ){
   	case 'view':
   		viewHello($option);
   		break;
   	
   	case 'comment':
   		addComment($option);
   		break;
   
   	default:
   		showPublishedHello($option);
   		break;
   }
   

2. Insert following function:

   
   function addComment($option)
   {
     global $mainframe;
     $row =& JTable::getInstance( 'comment' , 'Table' );
     if (!$row->bind(JRequest::get( 'post' )))
     {
       JError::raiseError(500, $row->getError() );
     }
   	
     $row->comment_date = date ( 'Y-m-d H:i:s' );
   	
     $user =& JFactory::getUser();
   	
     if($user->id)
     {
       $row->user_id = $user->id;
     }
   	
     if(!$row->store())
     {
       JError::raiseError(500, $row->getError() );
     }
   
     $link = JRoute::_( 'index.php?option='.$option.'&id='.$row->id . '&task=view' );
     $mainframe->redirect( $link, 'Comment Added' );
   	
   }
