Subscribe Plugin

Companion plugin to the MailerContrib, adding a "Subscribe me" link to topics to easily subscribe to topic changes

Example (only works if plugin is installed, and you are logged in (not TWikiGuest)):

Usage

  • Syntax: %SUBSCRIBE{...}% or simply %SUBSCRIBE%
  • Parameters:
    Parameter Default Meaning
    who Logged-in user Who to subscribe (wikiname, no web)
    topic Current topic Topic to subscribe to. Wildcards may be used e.g. topic="Item*" will subscribe to all topics starting with Item. Use topic="Main.*" to subscribe to the WebNotify for that web.
    unsubscribe Not set If set to "on", will unsubscribe the user
    format Simple HTML Link with an action anchor "Subscribe" or "Unsubscribe" Defines custom look-and-feel for subscribe link using the following format variables: $topics, $url, $wikiname, $action
    formatunsubscribe format Serves same function as format, but allows the user to define a different format than subscribe.
  • The button toggles subscribe/unsubscribe if the user is already subscribed or vice versa. So after the next click on the button, the user will be unsubscribed. The plugin updates the subscription lists in WebNotify.

Access Controls

The guest user is not allowed to subscribe for notification.

You don't need VIEW access to the WebNotify topic in order to subscribe to changes in a web, but you must have CHANGE access. If you want users to be able to subscribe or unsubscribe, but you don't want them to be able to modify their subscription or otherwise edit the WebNotify topic, you can restrict VIEW access to WebNotify. This will make it uneditable from the browser (but will not block save urls, so is not fully secure).

ALERT! Note that permissions on individual topics are not checked when subscription mails are sent out, so be very careful about who you allow to subscribe.
