Hi all,
I'm trying to figure out how to implement a form validation
of some fields, let's say a username. I have a form that inserts on
MySQL table, and when the user is typing the username, after it
looses the focus on field, validate it if there is a record on
table with the specified username. If so, validation will fail.
I already saw something similar with this on Dreamweaver MX
using some extension (because at that time, it did not support
ajax).
Kind regards, and thanks in advance.
