Improved interaction with attachments and DataForms

This plugin redesigns the way how users interact with topics and attachments in various ways:

Other features are:

  • cross-browser compatible bulk upload of multiple files
  • bulk actions on attachments: delete, move, hide, download as zip archive, create image gallery, insert links
  • thumbnail and lightbox preview of image attachments
  • easy renaming of attachments using modal dialogs
  • easy access to previous revisions of attachments
  • loading the list of attachments via ajax not to slow down display of topics with lots of attachments
  • filtering and pagination for topics with a lot of attachments
  • drag & drop upload for browsers supporting it (currently firefox and chrome only)

To activate you'll need to add topicinteraction to your SKIN path setting in your SitePreferences, like

    * Set SKIN = topicinteraction, pattern

Use the insidetab setting of MetaCommentPlugin to render comments inside a tab at the bottom of the page:

    * Set SKIN = topicinteraction, metacomment, pattern
    * Set COMMENTFORMAT = insidetab

Note you won't need using Foswiki:Extensions/NatSkin as that's integrated automatically.



TopicInteractionPlugin implements some macros to actually implement the user interface. These macros can be used for other purposes too of course.


List all attachments of a given topic. Without any parameters it displays a table of attachments similar to the one generated by the templates at the bottom of a topic. There are a couple of parameters that take regular expressions to limit the number of attachments to be listed.

"<topic>" topic whos attachments we want to query
attr="..." match the attachments' attribute
autoattached="yes,no,undef" limit attachments to those that are (not) autoattached
comment="..." match the attachments' comment
maxdate="..." specify latest attachment
maxsize="..." specify biggest attachment
mindate="..." specify earliest attachment
minsize="..." specify smallest attachment
names="..." match the name of attachments to be include in the list
user="..." match the attachments' user who uploaded it
footer="..." format string appended to the result
format="..." how to format each attachment
header="..." format string prefixing the resulting output
separator="..." format string put between each formatted attachment
hidenull="on,off" hide/display the empty result; only the header and the footer are included if set to "off" and there's no attachment at the given topic
nullformat="..." format string to be used when no attachments have been found and hidenull is switched off
nullheader="..." header string to be used when no attachments have been found and hidenull is switched off
nullfooter="..." footer string to be used when no attachments have been found and hidenull is switched off
sort="name,date,size,user,comment,comment:name" sort results by specified field
reverse="on/off" enable reverse sorting
limit="..." limit the number of attachments to the given number; by default show all

The following variables can be used in the format parameter:
  • $attr: the attributes
  • $autoattached: the autoattach flag
  • $comment: the comment field
  • $date(<format>): the attachment date using <format> to format the date
  • $date: the attachment date
  • $delete: the action to delete the current attachment
  • $deleteUrl: the url used in the delete action
  • $icon: img tag representing the filetype
  • $iconUrl: the url pointing to the icon used in the img tag
  • $index: the position index of the attachment in the result
  • $move: the action to move the current attachment
  • $moveUrl: the url used in the move action
  • $name: the name of the attachment
  • $path: the path property of the attachment
  • $props: the action to change the properties of the current attachment
  • $propsUrl: the url used in the props action
  • $size: the size in bytes
  • $sizeK: the size in kilo bytes
  • $sizeM: the size in mega bytes
  • $topic: the name of the topic of whose attachments are listed
  • $url: the attachments url
  • $urlpath: the attachments urlpath
  • $user: the user that uploaded the attachment
  • $web: the web name of the current topic
  • $webdav: the action to edit the current attachment using the Foswiki:Extensions/WebDavPlugin
  • $webdavUrl: the url used in the webdav action
  • $wikiuser: the user's home topic that recently changed the current attachment

The header and footer format strings may only contain
  • $count: the number of attachments found

The format, header and footer may contain the standard escape sequences:
  • $dollar: $ sign
  • $n: newline
  • $percnt: % sign
  • $quot: " sign

  header="| *&nbsp;* | *Name* | *Url* | *Size* | *Author* | $n"
  format="| $idnex | $name: | $url | $sizeK |"

%ATTACHMENTS{ header="| # | Icon | Name | Size | Author | Date |$n" format="| $index | $percntMIMEICON{\"$name\" size=\"48\"}$percnt | $name | $sizeK | $user | $date |" }%
