Hi Attaullah thank you so much.
I tried that one too but that file is storing in data.fs which i do not
want. i want to store my file to be physically stored. so for that i am
trying to write a python script. i have written many script but could not
get succeed
#!/usr/local/bin/python
"""This demonstrates a minimal http upload cgi.
This allows a user to upload up to three files at once.
It is trivial to change the number of files uploaded.
This script has security risks. A user could attempt to fill
a disk partition with endless uploads.
If you have a system open to the public you would obviously want
to limit the size and number of files written to the disk.
*"""
import cgi
import cgitb; cgitb.enable()
import os, sys
UPLOAD_DIR = "/home/praveen/Desktop/UPLOAD"
def save_uploaded_file (form_field, upload_dir):
"""This saves a file uploaded by an HTML form.
The form_field is the name of the file input field from the form.
For example, the following form_field would be "file_1":
<input name="file_1" type="file">
The upload_dir is the directory where the file will be written.
If no file was uploaded or if the field does not exist then
this does nothing.
"""
form = cgi.FieldStorage() ///when i tried to print form field its
returning None
if not form.has_key(form_field): return
fileitem = form[form_field]
if not fileitem.file: return
fout = file (os.path.join(upload_dir, fileitem.filename), 'wb')
while 1:
chunk = fileitem.file.read(100000)
if not chunk: break
fout.write (chunk)
fout.close()
save_uploaded_file ("/home/praveen/Desktop/1.html", UPLOAD_DIR)*
this script is not giving me error..
Is any one know script to save the file physically on the particluar
system.. suppose i have file in my Desktop and i have one interface(html
page with file text field) which provide to select you file and move to
another location /home/praveen/Desktop
Thanks
