[Zope] Using LocalFs in a form embedded in our application

25 May 2005

      Hi,

We are developing a web based application using Zope as webserver.

One of our expected features consists in uploading a zip file on the server
and after that to unzip it.

Our pages are designed using zpt.

I would like to include in one of my pages a simple form allowing to select
a file in the client machine and to upload it on the server (in a dedicated
directory, not in the zope DB).

I have installed LocalFS.

I try with a form like that in my code (copy/paste from the source code
provided by localFS in zope): 

<form action="manage_upload" method="post" enctype="multipart/form-data">
        <input type="file" name="file" size="25"/>
        <input class="form-element" type="submit" value="Add"/>
</form>

But nothing happen when I clic on the 'add' button. No upload, no error.

NB: this form is encapsulated in a macro (already encapsulated in a form),
is it the cause of the problem?

Someone have an idea??

Thanks in advance

Here is the source code of the macro which encapsulates the form:
