Restoring Upload File Path on form error?

[B. Perkins]

I have a form with a number of input fields which require validation.
I'm in the process of adding a file field so that users can also upload
some supporting documentation.

If the form doesn't validate due to missing or incorrect data I want to
redisplay the form with the original data. If I specify a document and
form errors exist, I can't restore the originally selected document path
string back into the input file field.

There are a couple of issues here:
(1) get upload remote filename may not return the full path to the
document on the browser machine.
(2) Using a value attribute in a file input doesn't appear to have any
affect? If I view the source I can see that inserted value, but it
doesn't appear in the field. This may be due to the fact that in (1) I'm
not getting the full file path.

So, assuming (2) should work, is there anyway to get the full path in (1)?

Active4D 4.0.2
Running under 4D Client 2003.7
NTK-based Web Server (Under Testing. I see this w/ ITK also)
4D Server 2003.7 running on Windows 2003 Server

Thanks,

Brad Perkins

I Googled this and it appears that what I'm seeing is a security precaution.

If anyone knows of a universal workaround I'd love to hear it, but it
sounds like this behavior will have to remain.

The filename sent by the browser is browser-specific. You can't rely  
on getting a full path. RFC 1867 (multipart/form-data) suggests  
sending only the filename.
