Next Previous Posts in Same Category
I’ve gotten a few emails about my (old) Next/Previous Post in Same Category plugin and about the fact that’s its broken - however, this functionality is now built into wordpress. (and I have it working on the site right now as a matter of fact). I’m a bit behind on what has been included with each new version of Wordpress, so I’m not sure when this made it’s way in there, but.. YAY! Now I don’t have to update the plugin! LOL! So, in any case, if you want to include links to the next/previous post in the same category as the one being viewed, you just need to do this (on the “single.php” template page INSIDE the “Loop“)
<?php previous_post_link('« %link', 'Previous post in category: %title', TRUE); ?>
<?php next_post_link('%link »', 'Next post in category: %title', TRUE); ?>
Where the first argument (where I have “« %link”) is the format of what is displayed… ie. if you want text before or a tag around the actual link (represented by “%link”) this is where you say how you want it to show.
And the second argument (where I have “Previous post in category: %title” is the text of the actual link. You don’t have to have the “%title” in there - but I think it’s useful)

What if a post is in multiple categories? Which one will it go to and how can you control which one it goes to?

Hmm… good question. AFAIK its just showing next/previous on one category - but how it decides which one (and how to get it to show the others)… not sure..

A long shot … any idea if it can be made to work on category children?

Thanks for posting this. I wouldn’t know it is already in the codex if not for your post. Is there a way to add the post excerpt right below the title? TIA.
