Search only in the same category as the current post or page (single page)

 There is no back-end option for this feature, but can be easily achieved by a small custom code. A similar code for archive pages can be found here.
​What is this, and where do I put this custom code?​
1
add_filter( 'asp_query_args', 'asp_posts_from_same_cat', 10, 2 );
2
function asp_posts_from_same_cat($args, $search_id) {
3
  $taxonomy = 'category'; // Enter the taxonomy name
4
  
5
  // Do not change anything below
6
  $categories = wp_get_post_terms( $args['_page_id'], $taxonomy, array('fields' => 'ids') );
7
  if ( !is_wp_error($categories) && count($categories) ) {
8
    $args['post_tax_filter'][] = array(
9
      'taxonomy'  => $taxonomy,    // taxonomy name
10
      'include'   => $categories,   // array of taxonomy term IDs to include
11
      'exclude'   => array(),
12
      'allow_empty' => false        // allow (empty) items with no connection to any of the taxonomy terms filter
13
    );
14
  }
15
​
16
  return $args;
17
}
Copied!
