Check category ID/name of next/previous posts in a loop…?

Hi. Found this. Hope it helps. Peter

https://www.ads-software.com/support/topic/how-to-get-next-post-id

example:

<?php $next = get_next_post();
if( $next ) :
$next_id = $next->ID;
	echo 'next post id: '.$next_id.'<br/>';
$next_cat = get_the_category($next_id);
$next_cat_id = $next_cat[0]->term_id; //'first' category only
	echo 'next post cat id: '.$next_cat_id.'<br/>';
//in case you need to know all categories of the adj post:
foreach($next_cat as $cat) { echo $cat->term_id; }
endif;

analogue for previous post

Thanks Peter!

…Oh, and thank you alchymyth! That’s exactly what I was looking for! Now that I know it all seems a bit ridiculous how I didn’t see get_next_post() in the codex from start… But, well, now everything just fell a little bit more into place. Again, thanks.
