ajaxify.php

<?php
	// Our Page Action
	public function pageAction ( ) {
		// Prepare our variables for our view
		// ...
		
		// Handle our view
		return $this->awesomeRender('page.html');
	}
	
	// Render Helper
	public function awesomeRender ( $template ) {
		// Get the full template path
		$template_path = ...
		
		// Render the template
		$template_html = $this->view->render($template_path);
		
		// Check for the XHR header
		if ( IS_XHR ) {
			// We are a AJAX Request, return just the template
			$this->sendJson({'content':$template_html});
		}
		else {
			// Wrap the Template HTML with the Layout and proceed as normal
			// ...
		}
		
		// Done
	}

Hi,

I use this little piece of code to output necessary DOM elements for classic and ajax requests :

$ajaxRequest = false;
if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') $ajaxRequest = true;
[...]

...

You example above seems to be more elegant, but could you explain how it works ?

@tezqa I think its code is using the PHP Zend Framework, which use the MVC pattern (http://en.wikipedia.org/wiki/Model-view-controller). You can learn more about Zend here http://framework.zend.com/manual/en/learning.quickstart.intro.html
