Changeset 47760 for trunk/src/wp-includes/class-wp.php

Timestamp:

Message:

Canonical: Redirect paged requests for a static page assigned as the "Posts page".

This avoids displaying duplicate content of the home page under different URLs with appended page numbers.

This change only affects the <!--nextpage--> pagination (page query variable) and not the regular multiple posts pagination (paged query variable).

The posts page does not support the <!--nextpage--> pagination, so requests for invalid page numbers should be redirected to the page permalink, applying the logic previously implemented for single posts or pages.

Follow-up to [34492], [47727].

Props jeremyfelt, sachit.tandukar, SergeyBiryukov.
Fixes #45337. See #40773, #28081, #11694.
