Subject: [EMAIL PROTECTED] Newbe needs help passing form data
Hello,
I am setting up my own Internet presence starting with
DNS and HTML
servers. I am teaching myself (as much as possible) how to write HTML
from scratch. Below you will find the server $ENV variables
which will
describe versions of the server etc. This is running on Linux
(LFS) 6.0
server. I have looked through at least the archives for this
month and
not found an answer to my problem as well as a number of books on the
subject of writing CGI (perl). So I ask you:
I have written a small HTML with a three field form that is
supposed to
pass the data to a perl script which in turn writes a dynamic
HTML page
based on the input to the form and sends it back to the browser.
According to all I have read if I use method==POST the form data is
supposed to be sent to the script via STDIN and if I use
method==GET the
data is sent via the $ENV{QUERY_STRING} variable. When using POST the
amount of data being sent is available in the $ENV{CONTENT_LENGTH}
variable. I have enabled everything I can find to run CGI on
the server
but I can not get the server to send any information to the script. I
created the perl script from the online Apache manual to dump all the
variables it is passing and the QUERY_STRING is empty and if
the form is
using POST the CONTENT_LENGTH==0. I am about 90% certain that I am
missing something in the configuration file but after days of looking
and reading I have not found out what it is. Running 'perl -w script'
with a QUERY_STRING environment variable set equal to good
data produces
a good looking HTML output so I will go out on a limb and say the
problem is not in the perl script. So, can anybody tell me what I am
missing? BTW, the CGI script does produce the static portion
of the HTML
so the script is running just not getting the form data. Thanks in
advance for any help you can give to point me in the right direction.
Below is a sanitized output from the Apache ENV dump script.
