XML-RPC Update Check


You can query core, plugin, and themes individually, or check all at once.

It defines four new methods:

  • xmlrpcCoreUpdateCheck – checks core, returns true/false
  • xmlrpcPluginUpdateCheck – checks plugins, returns true/false
  • xmlrpcThemeUpdateCheck – checks themes, returns true/false
  • xmlrpcUpdatesCheck – checks all of the above, returns an array of trues/falses.

The plugin was created primarily for WPUpCheck (, a simple
Windows application that remotely polls a WordPress site to see if updates are available.
