Generating prev/next link-rel navigational elements

Published: On Monday, June 2, 2008

.[invalid] This feature got implemented with WP version 2.8 so information in this article isn't as useful as used to be, anymore…

I would guess this is thing that no template can provide yet: navigational link elements (always inside head part).

This code (working since version 2.5) inserts correctly filled link-s on singular (post/page) pages and on archive-type pages too.

<?php if (!is_singular()) { ?>
<link rel="prev" href="<?php echo get_previous_posts_page_link(); ?>" />
<link rel="next" href="<?php echo get_next_posts_page_link(); ?>" />
<?php } else {?>
<link rel="prev" href="<?php echo get_permalink(get_adjacent_post($in_same_cat = false, $excluded_categories = '', $previous = true)->ID); ?>" />
<link rel="next" href="<?php echo get_permalink(get_adjacent_post($in_same_cat = false, $excluded_categories = '', $previous = false)->ID); ?>" />
<?php } ?>
What's this good for? It may bring some better understanding of website structure for search engines and it certainly brings usability/acces­sibility benefits for various apps, such as Opera browser. Why not to include this in the code of each site?

    Good idea, but it needs to fix outer situations like no existence of next post is.

    ↪ Shaman, good note, you are right, I know about this issue. Unfortunately, the code is going to get more complicated. :-)
