cgi type=file problems

[Maan Hamze]

If I understand you correctly, you need to be able to browse for a file in a
form that contains:

Case 1:  using enctype=multipart/form-data
<input="file" name=userfile" size=40 "enctype=multipart/form-data">    #put
in your own values

Then you want to browse and be able to get the file name that you pick from
the browse button.
If you submit this form using:

import cgi
form cgi.FieldStorage()
print form["userfile"].value

What you get is not the file name but the actual file (binary or text).  To
get the actual string in the field use:

import cgi
form cgi.FieldStorage()
print form["userfile"].filename

This prints the actual string in the field.

Case 2:  if you do not use enctype=multipart/form-data
THEN

print form["userfile"].value
does give you the actual string used through the browse button.
And
print form["userfile"].filename

prints None

does this cover what you want?
