Hi 1) yes, i'm using enctype="multipart/form-data" 2) i tried your proposal, but unfortunately the result is the same error message. Thanks anyway ph -----Original Message----- From: Dragos Chirila [mailto:d.chirila@finsiel.ro] Sent: lundi 11 octobre 2004 15:23 To: zope@zope.org; VIGNAUX Philippe Subject: Re: [Zope] picture as parameter for an external method Hi I assume that you set the following attribute for your form tag: enctype="multipart/form-data". Put a parameter in your python script called "filename" and process the form this way: picture = None if filename != '' if hasattr(filename, 'filename'): if filename.filename != '': picture = filename.read() and pass the "picture" parameter which is actually the picture (bytes).

Hi !

Is there a way to pass a picture (extension JPG) as a parameter of an

external method.

It seem to be the case as read on the internet but for me it doesn't work !

My zope config : Zope 2.6.4 (binary release, python 2.1, win32-x86), python 2.1.3, win32

This is the problem :

1) I've got a page template where I can choose a picture thru a < file

object :

<input type="file" name="filename">

2) This page template calls a python scripts

request=context.REQUEST

context.my_external_function( original_id=request['filename'] )

#context.my_external_function( request['filename'] )

3) my_external_function is defined in an appropiate module in the < Extensions > folder of my zope installation

def my_external_function (self, original_id):

pass

PROBLEM : when i run the process i get an error :

**exceptions.AssertionError**

Sorry, a site error occurred.

Traceback (innermost last):

* Module ZPublisher.Publish, line 150, in publish_module * Module ZPublisher.Publish, line 106, in publish * Module Zope.App.startup, line 225, in abort * Module ZODB.Transaction, line 135, in abort * Module ZODB.Connection, line 256, in abort

When i configure the whole thing to pass a normal parameter (text), it

works normally ; so obviously the problem is when trying to pass a picture.

Any idea ????

Thanks

Philippe
