If I pass parameters in this fashion, the web server will make them available in QUERY_STRING, but I need to use the GET method. The form is using the POST method so that the file that is being uploaded and processed gets handed to the cgi program through stdin. So looks like I can't have it both ways, i.e. POST and GET, stdin and query string env var.

The file would already exist on the client side. They are uploading the file to be
processed by this program MyCppProg.exe, which is invoked as a form 'action'. This
already works, but depends on the Apache variable REMOTE_USER being set when user logs
in, but we moving to implement a different method for authentication that involves
talking to two different Oracle databases, password rules, etc., so this REMOTE_USER
variable no longer gets set since we are bypassing Apache's authentication here.
So I need to set an 'environment' variable that remains visible to scripts and progs
within the session space, that can then be grabbed by the MyCppProg.exe, for example
with getenv("MyEnvVar"). It used to use getenv("REMOTE_USER").
I'm hoping to not have this variable have to be part of the file that gets uploaded.

jb

That is what I had tried before, using it as a hidden parameter. I will try passing as part of the explicit call to the prog as you describe. thanks, jb -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Session var read by form C++ CGI prog ?
Thanks, very much, Raditha.
Do you mean to pass my variable as a cgi parameter ?
If so, the problem is that this file that is being uploaded via the form to the
program MyCppProg.exe gets sent as THE input to the prog, apparently as a cgi-type
parameter through stdin (i.e. cin), so that when I try to pass the value as a cgi
parameter, it gets inserted INTO the file that is being uploaded.
Am I understanding correctly, or did I miss the point ?
Thanks,
JB

[PHP] Session var read by form C++ CGI prog ?
I need to use something like a session variable to make a variable available to an
existing form-invoked C++ program which takes as input a file being uploaded. Is this
even do-able ??If so, what am I missing here ???
The C++ prog used to use the REMOTE_USER env var set by the web server but we are no
longer doing authentication via the webserver itself, so this one does not get set,
and I need to set something myself. The C++ prog would had been grabbing this by
getenv("REMOTE_USER").
I was trying some php to set a session var 'UPATH' but the UPATH variable doesn't seem
to be visible to MyCppProg.exe :
--snip--
File to Upload:
--snip--
I am new to php, have been digging around on the web, and not making a lot of headway
quickly enough, so I'm asking.
Thanks,
JB
