Details edit

This hook is called by ContentHandler::canBeUsedOn() to determine whether a certain content model can be used on a certain title or not. This is checked, for example, on import or when moving pages .

  • $modelId: The content model ID, e. g. 'wikitext' or 'json'.
  • $title: The title where the content model may or may not be used.
  • &$ok: Whether the content model can be used on the title or not. Initially true; when you set this to false, you probably also want to return false; to skip the remaining hooks.
