get the full path of a file when using a WAFile Component

Hi everybody,

I am writing an intranet based on Seaside and I am struggling with a little problem.
I need to record and serialize some data about files I use in my application. So I tried out with WAFile Class to make it more ergonomic for the future user but my pb is that :

FIRST : I wrote this "html fileUploadWithCallback: [:f | file := f]"
where f is an instance of WAFile class; but with this class instances you can get only 3 attributes which are
- the contents (stream)
- the fileName (just the filename string without the entire path)
- the contentsType (text/plain, text/html ....)
But me I NEED THE FULLPATH OF THE FILE.HOW CAN I GET IT ?

SECOND : How could I create a WAFile class object using only the fullPath of a file ?

Thank you for your help!

You can't, basically because the standard disallows you to get the
full path (otherwise that would be a big security leak). THere are
still some old and buggy browser around, that provide the full path,
but you can't count on that.

Pleas avoid HTML mails in the future.

Cheers,

I read that as the full path to the file on the server-side. For
example, in PHP the file is uploaded to: $_FILES['userfile']['tmp_name']
and the original name (without path) would be in:
$_FILES['userfile']['name'].

Since you didn't mention anything about this Lukas, I'm guessing there
is no file server-side with Seaside, just the data held in an object. If
that's the case, then I guess you just open an output stream and write
out the data to a file of your choosing William.

I guess you'd just set the content: to an opened file-stream. Any
experienced smalltalkers know better?

Aha, ok I see. Seaside doesn't save the uploaded file anywhere
automatically, that's up to the developer to decide where to put it.
Maybe you want to save it to the file-system, maybe you want it in a
database, maybe you want to mail it somewhere, ... it is up to you.

Yeah, try something like (assuming that file is an instance of WAFile):

stream := FileDirectory default fileNamed: file fileName.
[ stream binary; nextPutAll: file contents ]
ensure: [ stream close ]

Then you have stored your file in the directory with your image.
Probably you should change 'FileDirectory default' to a different
subdirectory, to avoid accidental overriding of your image.

Cheers,
Lukas
