Dear R. Eric Wheeler,
Thank you! After several weeks of posting my question in several fora,
you are the first to reply with an example that works. Thank you! I am
so happy. After I have time to clean up the formatting and document it a
bit more fully I plan to post it everywhere, since no one seemed to know
how to make this simple and valuable example. I will give you credit,
and you deserve it!
One minor problem: the file is uploaded to the document root instead of
the $remoteDir directory. I can probably figure this out, but it would
help if you correct my code. I may have messed something up.
Here is your code after I modified it to work in my environment. Note
that I commented out your code to list the remote dir since it gave an
error message and I don't need it anyway. If there are no errors
detected, and it passes a simple test for successful upload once, I'm
satisfied that the file was uploaded.
One question: what is the "copy" function there for? I don't think I
need any files copied locally in order to upload a file.
One more question: can it work without knowing the user's password? I'm
thinking of disabling passwords on my remote webserver, so access is by
public/private keys only.
Thank you!
David
