An additional outputfilter that enhance file and image links informations in rich text

Project description

This product add a new outputfilter that generates additional informations for Tiny MCE’s internal link.

It’s a substitute of collective.tinymceplugins.advfilelinks, that doesn’t work with Plone >= 4.3 because it uses Products.TinyMCE >= 1.3.


For every link that points to an internal content (file or image), in the rendered html will be added some new informations:

  • The mimetype icon before the link text

  • The mimetype and filesize after the link text

  • The url of a File points to the direct download


Install collective.outputfilters.enhancelinks by adding it to your buildout:



 eggs =

and then run “bin/buildout”.

It doesn’t need to be installed.

Extending content-types

This product is modular, so if you want to add this feature (or more features) to some custom content-types you only need to provide a new adapter for the ILinkEnhancerProvider interface:


Then provide the Python adapter code:

from collective.outputfilters.enhancelinks.adapters import BaseEnhanceLink

class YourContentEnhanceLink(BaseEnhanceLink):

There are 4 basic methods for a basic override:

def get_url_suffix(filename):
    """ Return additional suffix to append at the end of the url """

def get_icon_url(mime_infos):
    """ Return the correct mimetype icon url """

def get_extension(content_file, mime_infos):
    """ Return the filename extension"""

def get_formatted_size(content_file):
    """ Return a formatted file size """

Additional mimetype icons

If you want more mimetype icons (for example for OpenOffice documents), you could add and install collective.mtrsetup in your buildout.



This product has been tested on:

  • Plone 5.0

  • Plone 5.1

  • Plone 5.2

It works with Dexterity-based ( standard File and Image content-types. If you want support for Archetype-based content-types or Plone 4 compatibility, go with versions < 1.0.0.
