plone.formwidget.multifile 1.0a5

z3c.form widget for adding multiple files

Introduction

plone.formwidget.multifile is a z3c.form-widget which lets users upload multiple files, either at once, or in batches using repeated form submissions.

Browsers that do not implement the file input “multiple” attribute are supported via javascript adding of multiple file inputs. This also works with browsers that do support “multiple”, and allows users to add and remove files in bundles. Upload does not occur until the form is saved.

Usage

Using the widget is quiet easy:

>>> from plone.directives import form as directivesform
>>> from plone.formwidget.multifile import MultiFileFieldWidget
>>> from plone.namedfile.field import NamedFile
>>> from zope import schema
>>> from zope.interface import Interface
>>>
>>> class IMySchema(Interface):
...     """My schema interface"""
...
...     directivesform.widget(files=MultiFileFieldWidget)
...     files = schema.List(title=u'Files',
...                         value_type=NamedFile())

Limitations

We do not yet support ordering. There is no fallback for non-html5, non-javascript browsers. They will only be able to upload 1 file at a time.

Changelog

1.0a5 (2013-01-21)

• Fixed bug on IE: When an file-input is opened via a scripted, forced click() event, IE won’t let you submit the form.

• Updated pt_BR translation.

1.0a4 (2012-12-20)

• Nothing changed yet.

1.0a3 (2012-12-20)

• Changed the UI so now there’s a link to “add files” instead of an standard input[type=file] HTML element (which still exists, but is hidden). Users were complaining that the old UI was confusing since the textbox of the input[type=file] element was always empty. [rafaelbco]

1.0a2 (2012-12-20)

• Removed integration with jQuery plugin. Instead we use HTML and javascript, and when applicable, the “multiple” extension from HTML5 which lets a user upload multiple files at once. [tmog]

• Fix minor bugs on the new non-flash implementation. [rafaelbco]

• Removed dependency on plone.app.drafts. [rafaelbco]

1.0a1 (2011-09-13)

• Initial release
