Front End : Lets assume our component is called gold

1- Create a sub folder for the component folder call it com_gold

2- Create a file called gold.php inside of it (Known as Entry Point)

<?php
defined(‘_JEXEC’) or die(‘Restricted access’);

require_once( JPATH_COMPONENT.DS.‘controller.php’ );

if($controller = JRequest::getWord(‘controller’)) {

$path = JPATH_COMPONENT.DS.‘controllers’.DS.$controller.‘.php’;

if (file_exists($path)) {

require_once $path;

} else {

$controller = ”;

}

}

$classname = ‘goldController’.$controller;

$controller = new $classname( );

$controller->execute( JRequest::getVar( ‘task’ ) );

$controller->redirect();

?>
?>

Back End :

1- Create a sub folder for the administrator/components folder call it com_gold

2- Create a file called admin.gold.php inside of it

Now you can Access the Component

http://localhost/joomla/index.php?option=com_gold

Adding :

1- Controller to Front End : The controller is responsible for responding to user actions

create a file called controller.php inside com_gold

<?php
defined( '_JEXEC' ) or die( 'Restricted access' );
jimport('joomla.application.component.controller');
class GoldController extends JController
{
    function display()
    {
        parent::display();
    }

}
?>

2- View to Front End : part of the component that is used to render the data from the model in a manner that is suitable for interaction

create views/gold/gold.html.php inside com_gold

<?php
defined( '_JEXEC' ) or die( 'Restricted access' );
jimport( 'joomla.application.component.view');
class GoldView extends JView
{
    function display($tpl = null)
    {
        $sentence = "Gold Component";
        $this->assignRef( 'sentence', $sentence );

        parent::display($tpl);
    }
}
?>

2- Template to Front End :

create views/gold/tmpl/default.php inside com_gold

<?php // no direct access
defined('_JEXEC') or die('Restricted access'); ?>
<h1><?php echo $this->greeting; ?></h1>
