This is last tutorial about adding comment at Joomla component. We will display list of comment below single posting (like usual blog, this site too).

1. Open "hello.php" within joomla/components. Update viewHello() function with following bold code:

   
   function viewHello($option)
   {
     $id = JRequest::getVar('id', 0);
     $row =& JTable::getInstance( 'hello', 'Table');
     $row->load($id);
   	
     if(!$row->published)
     {
       JError::raiseError( 404, JText::_('Invalid ID Provided'));		
     }
     HTML_hello::viewHello($row, $option);
   
     $db =& JFactory::getDBO();
     $db->setQuery("SELECT * FROM #__hello_comment WHERE hello_id='$id'");
   	
     $rows = $db->loadObjectList();
   	
     foreach($rows as $row)
     {
       HTML_hello::showComment($row);
     }
   
     $user =& JFactory::getUser();
     if($user->name)
     {
       $name = $user->name;
     }
     else
     {
       $name = '';
     }
     HTML_hello::showCommentForm($option, $id, $name);
   
   }
   

2. Open "hello.html.php", enter following function:

   
   	function showComment($row)
   	{
   	?>
     <P>
     <strong><?php echo $row->full_name; ?></strong>
     <em><?php echo JHTML::Date($row->comment_date); ?></em>
     </P>
     <P><?php echo $row->comment_text; ?></P>
       <?
   	}
