This may be triggered by the EditPage or any other facility that modifies page content. Use the $status object to indicate whether the edit should be allowed, and to provide a reason for disallowing it. Return false to abort the edit, and true to continue. Returning true if $status->isOK() returns false means "don't save but continue user interaction", e.g. show the edit form.

  • $content: content of the edit box, as a Content object.
  • $status: Status object to represent errors, etc.
