Joomla - Component: a Hello page

After build list screen at front end, we want to display single data in a page. Now, we will build single page data with link to back frontpage.

Open "hello.php", update with following code:

switch( $task ){
  	case 'view':
    viewHello($option);
    break;

  default:
    showPublishedHello($option);
    break;
}

add viewhello() function:

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);
}

Open "hello.html.php". Add following function after showhello():

	function viewHello($row, $option)
	{ ?>
  <p class="contentheading"><?php echo "ID: <b>". $row->id ."</b>";?></p>
  <p><?php echo "Message: <br><b>". $row->message . "</b>";?></p>  

  <?php $link = 'index.php?option='. $option; ?>
  <p><a href="<?php echo $link;?>">< return to the hello frontpage</a></p>  
  <?php
	}
