Description
Prior to 4.4 was able to append extra pages to the end of posts with the following:
<?php add_action('template_redirect', 'custom_content_one'); function custom_content_one() { global $post; $content = "\n<!--nextpage-->\nExtra page v1"; $post->post_content .= $content; }
Since the release of 4.4 the above code no longer works. I tried leveraging the new content_pagination filter as well as hooking into the_post but the issue remains.
<?php add_filter('content_pagination', 'custom_content_two', 10, 2); function custom_content_two($pages, $post) { if ( in_the_loop() && 'post' === $post->post_type ) { $content = "Extra page v2"; $pages[] = $content; } return $pages; } add_action('the_post', 'custom_content_three'); function custom_content_three() { global $multipage, $numpages, $pages; $content = "Extra page v3"; $multipage = 1; // ensure post is considered multipage: needed for single page posts $numpages++; // increment number of pages $pages[] = $content; }
All of the above methods add the additional page to the post's pagination but visiting the extra page triggers a 404 error (if redirect_canonical is not disabled redirects to page 1 of the post).
However, the issue only occurs on posts that already have multiple pages. If the page does not, then the extra pages function as intended.
Pagination is disabled and I have tried both of the following fixes with no change in behavior:

Observation:
On posts that already contain multiple pages, $wp_query->queried_object is empty on the additional page, while it's populated on posts that only contain one page.
The above should say that permalinks are disabled, not pagination.
