Manual:Hooks/APIQueryInfoTokens

Details
use this hook to add custom tokens to prop=info.

Every token has an action, which will be used in the intoken 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. The prototype of the callback function is func($pageid, $title) where $pageid is the page ID of the page the token is requested for and $title is the associated Title object. In the hook, just add your callback to the $tokenFunctions array and return true (returning false makes no sense)


 * $tokenFunctions: array(action => callback)
