I'm working on an ftp login form using PHP. I'm trying to set it up so that
the PHP file is self calling. eg. file FTP.PHP displays an html form in
which the form action setting calls FTP.PHP. Essentially the program does
the following:

1) Display a form prompting user to enter username and password. Ftp server
location is hard coded into PHP page.

2) User clicks on Login/Submit button which calls ftp.php. Code at beginning
of php file (prior to aforementioned form data) checks if a username and
password was passed. If so an attempt to connect ot the hardcoded ftp server
is made with said username and password. If connection fails, login form is
displayed with a message "Login failed, please try again."

3) If connection was successful, open url
ftp://username:password@ftp.mydomain.com

What I'm finding during testing is that the first time I run the page, user
name and password information is passed back to the program (I've turned on
globals in my php.ini file and included a foreach line that echos the
contents of the $_REQUEST array to show what was passed.) But as of this
point entering new login information and clicking on Submit/Login always
returns the same data. Personally, I'm not even sure if the action is
re-running.

Does PHP support the writing of scripts which with forms whose actions are
self calling? eg. the form created by ftp.php calls ftp.php.

If so, is there anything I need to do to flush the $_REQUEST buffer between
presses of the SUBMIT button?

FYI, Windows 2000 server with IIS 5 (I think it's 5?) and PHP.EXE version
4.3.1.1 (I tried installing a newer version of PHP several months ago but it
promptly broke all of my existing PHP based applications. In short, I'm
staying with this version for the time being.)

I look forward to your comments and suggestions
