Yes, *If the user hits refresh after submitting the form they will
refresh **
*nextpage.php. Which is going to resubmit the data to mysql? (duplicate
entry)**
No, you didn't read what I wrote.
The form submits to formhandler.php which submits the data to MySQL and
then redirects to nextpage.php. Nextpage.php *does not* submit any data
to MySQL. Read my post again, carefully this time.
And please include the list when replying.

Disabling client-side features like refresh and back is not the right
way to solve this problem. The most common solution is to redirect the
user to the next page from the form handler rather than outputting the
next page from the form handler.
For example...
form.php shows the form, which submits to formhandler.php which
processes the form and then does a header('Location: ...') redirect to
nextpage.php.
If the user hits refresh after submitting the form they will refresh
nextpage.php. If they hit back they will be taken back to form.php.

Sam,
Sorry to disappoint you, but this is also a client-side value, not a
server-side value. You can't get to it.
Thank you,

Subject: [PHP-WIN] How to read the username
I need my webpage to read the username of the PC (machine). Is it possible to
do this with PHP?

Yes it is, but you need to set it up right. What you're after is NTLM
authentication. If you're using IIS then this is pretty easy, just
change the permissions on the website to require authentication. If
you're using Apache you'll need to find a module to handle this for you,
there are several but it's been a while since I've looked into this.
In short, Google for "NTLM authentication" and add the name of your web
server. When I did this a few years ago with Apache running on FreeBSD
it took a while to get it set up and working properly, but it was worth it.

I have to different pages (forms) one.php and two.php I created two different
pages (onemysql.php and twomysql.php) to handle myql data for each of them I
add header("Location: one.php"); to onemysql.php
And header("Location: two.php"); to twomysql.php
one.php works fine. two.php give me this Warning: Warning: Cannot modify
header information - headers already sent by (output started at C:\Program
Files\xampp\htdocs\xampp\Activity_Log\html\twomysql.php:1) in C:\Program
Files\xampp\htdocs\xampp\Activity_Log\html\twomysql.php on line 3
