Related Products exclude category

Hi @bernaertsmusic

Currently, there are no settings to exclude a specific category from related products. But there is the option to select a specific category to include.

If the default WooCommerce related product option is not disabled in the plugin settings, the below code snippet can be used to exclude specific categories.

add_filter( 'woocommerce_related_products', 'wt_exclude_product_category_from_related_products', 10, 3 );

function wt_exclude_product_category_from_related_products( $related_posts, $product_id, $args ) {
	// Add the product categories slug to exclude
	$term_slug[] = 'fabric-patterns';
	$term_slug[] = 'cabin';

	// Fetch the product Ids in the defined product categories
	$exclude_ids = wc_get_products( array(
		'status'	 => 'publish',
		'limit'		 => -1,
		'category'	 => $term_slug,
		'return'	 => 'ids',
	) );

	// Remove the products from the selected categories
	return array_diff( $related_posts, $exclude_ids );
}
