This Mod plugin displays a chat (using phpfreechat) in a wiki page.
phpFreeChat is a free, simple to install, fast, customizable and multi languages chat that uses a simple filesystem for message and nickname storage. It uses AJAX to smoothly refresh (no flicker) and display the chat zone and the nickname zone. It supports multi-rooms (/join), private messages, moderation (/kick, /ban), customized themes based on CSS and plugins systems that allows you to write your own storage routines (ex: Mysql, IRC backends …), and you own chat commands !
N.B.: This procedure has been tested on a Tiki 6.0-6.1. Perhaps this line of code is going to be added in next versions.
G.I.: In tiki version 9.1, the file js_detect.php has been renamed to javascript.php and portion of the code has changed. I have yet to test where to put the aforementioned lines of code.
