Show active post title on widget

This will add the current post at the top of the related posts list. Put in in your (child) theme’s functions.php file.

add_filter( 'related_posts_by_taxonomy', 'my_theme_related_posts_add_current', 10, 4 );

function my_theme_related_posts_add_current( $results, $post_id, $taxonomies, $args ) {

	// Check if it's related posts for a widget or shortcode.
	if ( ! in_array( $args['type'], array( 'widget', 'shortcode' ) ) ) {
		return $results;
	}

	// Check if fields is empty (not used by widget or shortcode).
	if ( $args['fields'] ) {
		return $results;
	}

	// Get the current post.
	$curr_post = get_post( $post_id );

	// Check if current post and related posts are found. 
	if ( $curr_post && ! empty( $results ) ) {

		// Add the relatedness score to the current post.
		// Could be usefull if needed later in the process.
		$count = count( $args['related_terms'] );
		$curr_post->score = array( $count, 0 );
		$curr_post->termcount = $count;

		// Add current post to the related posts.
		array_unshift( $results, $curr_post );
	}

	return $results;
}

btw:
consider creating a child theme instead of editing your theme directly – if you upgrade the theme all your modifications will be lost. Or create a plugin with the code above.
