Question

Looking to exclude specific category (ID = 100) from "Related Posts" feed at bottom of Blog pages. Extra bonus if it can also exclude from the sidebar archive (not sure if they are connected??)

I'm using WP Theme "TheFox", have asked them - not part of their theme.

I "think" it has to do in the functions.php. I have found some similar questions, and code, but have not had any luck.

I'm a complete noob for .php, so be gentle :)

I've found some other attempts, no luck. Not registering or effecting the feed.

$categories_to_exclude [ 100 ];
$first_cat  = false; 
$categories = get_the_category( $post->ID );
while ( ! empty( $categories ) && false === $first_cat ) {
 if ( in_array($categories[0]->cat_ID, $categories_to_exclude) ) {
  array_shift($categories);
 }
   else {
       $first_cat = $categories[0]->cat_ID;
   }
}

What I could gather from your question is that You want to ignore one category (may be more) in the related post query?

use the following CODE (some explanation is given within the CODE in comments):

// set the category ID (or multiple category IDs) // you want to ignore in the following array $cats_to_ignore = array( 2 ); $categories = wp_get_post_categories( get_the_ID() ); $category_in = array_diff( $categories, $cats_to_ignore ); // ignore only if we have any category left after ignoring if( count( $category_in ) == 0 ) { $category_in = $categories; } $cat_args = array( 'category__in' => $category_in, 'posts_per_page' => 4, 'orderby' => 'date', 'post__not_in' => array( get_the_ID() ) ); $cat_query = new WP_Query( $cat_args ); while ( $cat_query->have_posts() ) : $cat_query->the_post(); /* just example markup for related posts */ echo '<h2><a href="' . get_the_permalink() . '">' . get_the_title() . '</a></h2>'; endwhile; // reset $post after custom loop ends (if you need the main loop after this point) wp_reset_postdata();
