<?

/*		TicketCFC class v1.1 - Chuck Harper
		Based on code originally written for /classes-aeglive/display/TicketURLWrapper.php written by Matt Leonard
		
		This class must be embedded near the top of every page on the site in order to capture the cfc into a
		session variable when the user first lands on the site.
		
		If a CFC is appended to the page url it is stored in a session variable.
		Then anywhere a ticket url is displayed the wrapURL function (used staticly) 
		can encode the url to include the cfc and brand for ticketmaster links.
		If no session stored CFC exists wrapURL uses the default CFC defined in the site's config file.
		
		Version history is at the bottom of the file.
		
		EXAMPLE CODE:
		require_once($_SERVER['DOCUMENT_ROOT'] . '/classes/TicketsCFC.php');
		define('BRAND','aeglive');	// tells ticketmaster to skin the ticket site to match aeglive.com
		define('CFC','AEGLIVE_MAIN');	// this is the default cfc to use if there is no session stored
		$txtTicketBuyLink = TicketsCFC::wrapURL($xml->item->ticket_link,BRAND,CFC);
		
		EXAMPLE URLS:
		http://www.aeglive.com/?cfc=AEGLIVE_BANNERSAMPLE
		http://www.aeglive.com/showdetail.php?id=23670&detail_type=event&cfc=AEGLIVE_BANNERSAMPLE

		// we're going to ignore the ones that lack the word "ticketmaster" for now

		// .com is "US style" and the majority of what we'll find - ideally, it should be of the "event" type and wrapped to look like:
		// http://www.ticketmaster.com/cgi/outsider.plx?CAMEFROM=CFC&GOTO=http://www.ticketmaster.com/event/EVENTNUM?brand=aeglive
		// but some can't because they're "artist" or "venue" links or just plain weird
		//
		// .ca should also be wrapped US style
		//
		// .co.uk and .ie are "UK style" and should eventually look like:
		// http://www.ticketmaster.co.uk/event/EVENTNUM?brand=uk_aeg_online&camefrom=CFC_UK_AEGLive_WMAIN000000WEB
		// NOTE: 2/17/09 until skins for ticketmaster.co.uk are made for aeg & gv .co.uk, no brand in database, but there is a CFC for both
		// so for now, link should look like:
		// http://www.ticketmaster.co.uk/event/EVENTNUM?camefrom=CFC_UK_AEGLive_WMAIN000000WEB
		//
		// all other ticketmaster.* sites will just be pushed through because we don't have branding and CFCs working
		// with them yet - but they will be identified so putting in branding/CFC later should be easier
		//
		// here's a sample of some links found in the "link" table (with link_type_id=11) (the code must gracefully handle all of these plus more)
