[Zope] add a File type via a form

[Mihamina Rakotomandimby]

Hi,
I have a very simple "index_html".
It s a form in which I ask for an "Id"


	<form action="addFile" method="post">
    	<div>Id</div>
    	<input 	type="text" 	name="id" 	size="40" />
    	<input	type="submit" 	name="submit" 	value="Add File" />
  	</form>

what I want is when the visitor fill the form and then submit it, a
"File" object is created inside the same container.

I added a Python script named "addFile" in the same container, and tried
some things... but always failed.

How to create a "File" then?
Thank you.

PS: I know the danger if an anonymous can do such things as creating an
object into a container, but it's just for learnig prupose at the
moment.
