python cgi problem with textarea

[Adrian Smith]

This may be more a cgi thing than a Python one, but I'm trying to get
this page:

http://adrian10.phpwebhosting.com/trial.html

consisting basically of this:

<FORM ACTION="/cgi-bin/python3.cgi" METHOD="POST">
<TEXTAREA NAME="essay" COLS=60 ROWS=20 WRAP=HARD></TEXTAREA>
<P><INPUT TYPE=SUBMIT VALUE="submit" NAME="submitbutton">
</FORM>

....to print out the contents of the textarea with this cgi script:

#!/usr/bin/python
import cgi
print "Content-type: text/html\n"
form = cgi.FieldStorage()
print form["essay"].value

....and I get an internal server error if I have any spaces in the
textarea, which is really going to limit its usefulness to me. Oddly,
it seems to work for a friend in the UK who's looked at it, but it
doesn't work for me here in Japan.

i just tried it and its working. here it is

http://yallara.cs.rmit.edu.au/~bevcimen/form.html

maybe the internal server error is because mod_python isn't installed
assuming your using Apache as your web server

And what error appears in the server error log?

Yeah, but it wouldn't work *at all* in that case, would it? ATM it
seems to work as long as the textarea input has no spaces.

I've just asked my web provider why I don't appear to have a server
error log, as a matter of fact - I'll post it if and when they reply.

You do not need mod_python installed to be able to run CGI scripts,
thus has nothing to do with mod_python.

it doest work because the "space" character isnt interpreted
correctly, you need
to change the space characters too &nbsp;

While debugging you should put

#!/usr/bin/python

import cgitb
cgitb.enable()

import cgi
print "Content-type: text/html\n"
form = cgi.FieldStorage()
print form["essay"].value

at the beginning of your cgi -- just in case the error is in the python
script.

What??? Did you even read the problem description?

oops...i did read the problem description, but i when i tried the code
it worked for me and when i put spaces into the TextArea it wasn't
reflected correctly back. So i thought this was the problem.

Adrian, can you still try replacing spaces with &nbsp; via the
following;

#!/usr/bin/python
import cgi
import urllib
import cgitb
cgitb.enable()
print "Content-type: text/html\n"
form = cgi.FieldStorage()
#print urllib.quote_plus(form["essay"].value)

for char in form["essay"].value:
if char == ' ':
print "&nbsp;"
else:
print char

I'll try it...but I think it may be a problem on the server end. It's
not showing up in the server logs, either.
