Called from: File(s): page/Article.php

For examples of extensions using this hook, see Category:IsFileCacheable extensions.


  • $article - The article object.

Return value

  • true if cacheable
  • false if not cacheable

The hook isFileCacheable is not the sole determinant of whether a particular wiki page is cacheable or not. Whatever hook function you write is AND'ed with other boolean tests to determine cacheable status.
