Manual:Hooks/APIQueryRecentChangesTokens

Details
use this hook to add custom tokens to list=recentchanges.

Every token has an action, which will be used in the rctoken parameter and in the output (actiontoken="..."), and a callback function which should return the token, or false if the user isn't allowed to obtain it. he prototype of the callback function is func($pageid, $title, $rc) where $pageid is the page ID of the page associated to the revision the token is requested for, $title the associated Title object and $rc the associated RecentChange object. In the hook, just add your callback to the $tokenFunctions array and return true (returning false makes no sense)


 * $tokenFunctions: array(action => callback)
