Batch Upload Plugin

This plugin intercepts the TWiki:Codev.BeforeAttachmentSaveHandler to process a zip file, attaching each of the individual files to the designated topic instead of the zip file.

Syntax Rules

• None - it applies as long as it is enabled. (Off by default)

Examples

• N/A

Plugin Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, e.g., %BATCHUPLOADPLUGIN_SHORTDESCRIPTION%

• One line description, is shown in the Text Formatting Rules topic:
  • Set SHORTDESCRIPTION = Plugin implementing TWiki:Codev.MultipleAttachmentsAtOnce

• Debug plugin: (See output in data/debug.txt)
  • Set DEBUG = 0

• If disabled, does nothing.
  • Set ENABLED = 0

Plugin Installation Instructions

Note: You do not need to install anything on the browser to use this plugin. The following instructions are for the administrator who installs the plugin on the server where TWiki is running.

• Download the ZIP file from the Plugin web (see below)
• Unzip BatchUploadPlugin.zip in your twiki installation directory. Content:

  File:	Description:

• (Dakar) Visit configure in your TWiki installation, and enable the plugin in the {Plugins} section.
• Flip ENABLED switch to 1
• Test if the installation was successful:
  • try uploading a zip file

Caveats

• • Required support (add an attachment) not in TWiki::Func, so I call TWiki::UI::Upload
  • UPLOADZIPLIMIT, UPLOADNOSPACES, UPLOADLOWERCASE features deleted - belong in upload
  • PNG support deleted (should be in TWiki::UI::Upload)
  • No longer uses oops templates (plugins can't use them)
  • Dies instead of finishes, because otherwise it can't veto zip attach
  • Doesn't carry through the hide or link flags
  • Comment field on extracted files is not customisable

Further Development

• • Put back deleted functionality.
  • TWiki:Codev.BeforeAttachmentSaveHandler needs veto capability
  • Ugly die needs replacing
  • Test what happens if you upload zips of zips
  • There is a method - currently called findTopicForPicture which is disabled by default - this can be used to change the destination topic for each archive element. We need a TWiki:Codev.ExtensionInteractionPoint to allow plugins to have their functionality overridden.
