Hi gang:
This is probably trivial for most of you, but here's my solution to
the problem I presented earlier.
The problem was, I just wanted to be certain that if a use clicked a
button that they could only do it once. Sounds simple enough, huh?
Certainly, one can use javascript, but I wanted something that was
basic php and html -- here's my solution with code (please provide
critical review):
http://www.webbytedd.com/cc/submit-once/index.php
If the user clicks "Submit once", then that's the way it is until
they quit their browser. If they don't quit their browser, then no
amount of refresh will allow them to click the button again.
The "Reset Submit", of course, resets this condition but it's for
demo purposes.
What I have not solved, and I don't think there is a solution (I
could be wrong) is to prohibit the user from clicking the back button
on their browser to reset this condition.
I've done a considerable amount of javascript reading, testing, and
code search and have not found anything that works -- and -- I have
even found places where the js community says that nothing will work
to solve the back-button problem.
So, does anyone here know better? If so, please start a different thread.
Cheers,
tedd
