/* Personalize Snippet for Revolution */

/* ::::::::::::::::::::::::::::::::::::::::
* Snippet Name: Personalize
* Short Desc: returns a chunk if the user is logged in, otherwise calls another
* Version: 3.2
* Created By: 	Ryan Thrash ([email protected]), and then
* powered up by kudo ([email protected]), and then
* updated to work with 0.9.6 by breezer
* MODx Revolution version by Bob Ray
*
* Date: Aug 03, 2006
*
* Changelog:
* Dec 01, 05 -- initial release
* Jun 19, 06 -- updated description
* Jul 19, 06 -- hacked by kudo to output chunks
* Aug 03, 06 -- added placeholder for username
* Aug 06, 07 -- renamed to LoggedOrNot as its more fitting, it also matches the example
* Aug 06, 07 -- replaced 2.0 code with modified version found here
* Sept 26, 10 -- MODx Revolution version
*::::::::::::::::::::::::::::::::::::::::
* Description:
* Checks to see if webusers are logged in and displays yesChunk if the user
* is logged or noChunk if user is not logged. Insert only the chunk name as
* param, without {{}}. Can use a placeholder to output the username.
*
* TESTED: can be used more than once per page.
* TESTED: chunks can contain snippets.
*
*
* Params:
*    &yesChunk [string] [REQUIRED]
*        Output for LOGGED users
*
*    &noChunk [string] [REQUIRED]
*        Output for NOT logged users
*
*    &ph [string] (optional)
*    Placeholder for placing the username
*    ATTENTION!: ph placeholder will *not* be set in noChunk!
* 
*    &fullName [`0` or `1`] (optional)
*    Use full name instead of username in placeholder
*
*
* Example Usage:
*
*    [[!Personalize?
*        &yesChunk=`HelloUser`
*         &noChunk=`Register`
*         &ph=`name`
*     ]]
*
* Having Chunks named HelloUser and Register, the first will be
* shown to a user logged on in the current context,
* the second to other users.
