File uploading support

How can I upload file via CB?

[Evan Miller]

Try Req:post_files(). I think it will give you a list of temporary
files in the POST request.

Hi Evan,

I use Req:post_files() but it is always empty.

Do I need to do something in my (html) form ?

Please advise.

Hmm, this works for me. Make sure that the server can write to the "scratch" directory of your project.

Hi Evan,

Yes, it works.  Sorry I forgot to put some additional info after I got it to work.

<form method="post" enctype="multipart/form-data">

That's the key.  After that it works like magic.

I really enjoy the fact that the uploaded files are stored in scratch, and that the entire information about the file is available

as a result, but the filename is a pain :)

Anyhow, it works.

Not exactly a complete example, but code from my (working) application . . . . .

    [{uploaded_file, FileName, Location, Length}] = Req:post_files(),
    Fname = "./priv/static/lb/headers/" ++ FileName,
    file:copy(Location, Fname),
    file:delete(Location),

Hope this helps a bit

no way to save a file from cb_admin?

something like this (it's just an invention)

152                 'POST' ->
153                     Record = lists:foldr(fun
154                                 ('id', Acc) -> Acc:set(id, 'id');
155                                 (Attr, Acc) ->
156                                     AttrName = atom_to_list(Attr),
157                                     Val = Req:post_param(AttrName),
158                                     [{_, FileName, Location, Length}] = Req:post_files(),
159                                     Val1 = case erlang:length(FileName) > 0 of
160                                                true ->
161                                                    Fname = "./priv/static/" ++ FileName,
162                                                    file:copy(Location, Fname),
163                                                    file:delete(Location),
164                                                    Fname;
165                                                _ -> Req:post_param(AttrName)
166                                            end,
167                                     Acc:set(Attr, Val1)
168                             end, DummyRecord, DummyRecord:attribute_names()),
