How do I retrieve the full path (C:\.....filename) of a file uploaded to a php script on the server.
I think $_FILES will only provide 'name', which is only the filename itself.

Thanks, Don

That information usually isn't sent. And see RFC2183 sec.
2.3 (http://www.ietf.org/rfc/rfc2183.txt ).

But $_FILES['foo']['name'] will be empty if no filename is
given to the server. Although they 'should attempt to
supply a file name for each submitted file' (HTML4.01 sec.
17.3.4), user agents are not required to supply them.

HAGW!

I wonder if javascript could get it from the fileupload box, attach it to
a hidden form, which is available on the next page as a post. Never tried
it tho.

I'm not sure how to construct the javascript to do what you recommend. Can you show me an example?

try this...

assuming you have the standard fileupload box in a form, call it myimage,
and the form is myform, add an onfocus function call to the upload box to
call a function named as you choose.

In the box put
onFocus="passfilename();"

In the function put:
filename = document.myform.myimage.value;

'filename' will be whatever is in the box. then attach that value to the
hidden field with

document.myform.hiddenfield.value = filename;

and submit the form.

use POST to get the value as you would any other. dont know whether it
will balk at the slashes and colon.

Theo,

IT WORKS!! I did exactly as you recommended, and it works just great. You don't know how relieved
I am that this is working. Thank you so much. I don't know what I'd do without these news groups.
What a tremendous asset. When I'm good enough, I expect to do my share of helping others.

Thanks again,

Jeff North

Don, just out of curiosity, why do you want the information on where
the users is uploading the file from?

Jeff,

It's complicated. I'm providing an improved version of a chat group page which has very limited
capability for attaching pictures. I'm reading in the original page, modifying it to include adding
browse boxes for uploading pictures. The user clicks on a "Preview" button, afterwhich a
server-side php script uploads the files, then provides back to the client page a preview of the
results of his pending post. That preview includes the same form data that he entered on the
original page, including the file browse boxes. This allows him the opportunity to make any
changes, afterwhich he clicks on "Previw" again, or "Post", which sends the info to the original
chat group for posting.. Everything seems to work okay, but now just discovered even though I have
the full path to his original file, I can't populate the original browse box for a <input
type=file...>. DARN! Guess the browser is designed that way for security reasons. So, guess I'll
have to come up with another approach. This has been a real learning curve for me, but I'm having
fun. Things are coming together pretty well. Just wish I could come up with an answer on this one.
If you have any ideas I'd appreciate your feedback.

Thanks for your inquiry.
Regards, Don

I don't know if this is going to help or hinder your progress.
If you look at the discussion forum on
http://www.interactivetools.com/forum/forum.cgi?forum=18; then do a
search on image, image preview etc. The basic app (htmlArea) simply
has a dialog box where you type in the url of the image. Other people
have wanted image preview (amongst other things). It might give you an
idea of what is involved. You might even find some code there that you
can use.

Also, if you still have the full path and filename in the input box
you might want to prepend file:/// to the name.

Thanks Jeff. I checked out that forum. It looks like it should be of great help.
