Hi all.
I have a requirement, wherein I need to allow vanilla uploads of files
to a HTTPD server.
Any client can upload any number of files (one at a time).
Also, there is just one directory, where the files get stored
"finally" (that is, after being copied from the temporary location,
via "move_uploaded_file")
Also, I have been able to get the simple file uploading running via
PHP, by picking up one of the numerous "Hello World" examples
available :)
Now, I am facing the following use-case ::
1)
User 1 starts uploading a large file, say "big_file.avi".
2)
Meanwhile, user 2 also starts uploading a (different) file, but with
the same name "big_file.avi".
In an ideal scenario, user 2 should be prompted with a message, that a
file of the same name is already being uploaded by someone else
somewhere.
Is there a way to do this?
( Note that, had the user 2 started uploading AFTER user 1 had
finished with the upload, we could probably modify the PHP-script at
the sever-side, to let user-2 know that a file of the same name
already exits. But I am failing to find a solution, when the user 2
starts the upload WHILE the large file of user 1 is in the process of
completing uploading).
Any way the issue may be solved?
I will be grateful for any pointers :)
Regards,
Ajay
Hi,
This is not possible with PHP, PHP will not know about the file until the
upload is completed. You can use HTML5 or flash(not recommended) for an
alternative way of uploading, and then you can check the file name in
advance.

As Matijn said, you don't know the name until your php processes the
file that has been uploaded alreaday. But my solution will work for you
- you just have to save it under the temp name until the user responds
to your message and request for a new title. You may have to run a
periodic script to clean up any files with your temp names that the user
declined to re-name for you. I'd make up a temp name with some special
prefix so that you can find and delete them.
