For a nonprofit networking site I need to create a small and simple chat functionality, that allows
a) all registred users to enter a chat
b) only selected members to enter chat
c) private chat between two persons.
I have some experience in php and mysql I'd like to write the chat functionality myself,
also the site where it has to be integrated I've started in php with msql,
but since I have no experience with chatboxes, I did search for some
chat-related tutorials and informations found this one (amongst others on the same site):
http://www.tutorialized.com/view/tutorial/A-MySQL-Driven-Chat-Script/16 (only the
extra javascript functions for buttons i'd like to leave away from that script.)
Now , while gathering some understanding for chatboxes, I came across the information that says
that the meta tag refesh is causing some flickering in some browsers, which would be indiscussable
in terms of user-friendliness and profesionality, but which alternatives do i have ?
I read that there is a clientside refresh solution with javascript and frames, but in this case I'd need to
provide an alternative for users who have switched off the javascript in their browsers or who'd
use simple textbrowsers.
So, I made my points, again, in short:
- basic fucntionality needed: input of pure, simple, unformatted text by users, that appears in a box after submit,
it has to made sure that all input done by participating users appears in box visible by all other
participants after they click submit (refresh or other method ?).
- preferably php, mysql in form of tutorial or small, simple and easily modifiable open source script.
- no side effects such as flickering (?? is it really that bad ?),
- no diminution in 100% accessability, validity, usability.
