◆ fixRedirect()

RefreshLinks::fixRedirect (   $id)
private

Update the redirect entry for a given page.

This methods bypasses the "redirect" table to get the redirect target, and parses the page's content to fetch it. This allows to be sure that the redirect target is up to date and valid. This is particularly useful when modifying namespaces to be sure the entry in the "redirect" table points to the correct page and not to an invalid one.

Parameters
int$idThe page ID to check
