Exclude Certain Products from Wishlist

Hello there,
we hope you’re doing well!

In order to exclude certain product categories for the wishlist, add this code in the functions.php file of your active theme:

if ( ! function_exists( 'yith_wcwl_show_add_to_wishlist_button_exclude_categories' ) ) {
	function yith_wcwl_show_add_to_wishlist_button_exclude_categories( $show ) {
		global $product;

		$excluded_categories = array(
			'category-1',
			'category-2',
		);
		$product_categories = wp_get_post_terms( $product->get_id(), 'product_cat' );
		$product_categories = $product_categories ? wp_list_pluck( $product_categories, 'slug' ) : array();

		if ( array_intersect( $excluded_categories, $product_categories ) ) {
			return false;
		}

		return $show;
	}
	add_filter( 'yith_wcwl_show_add_to_wishlist', 'yith_wcwl_show_add_to_wishlist_button_exclude_categories', 10, 1 );
}

And for exclude some products:

if ( ! function_exists( 'yith_wcwl_show_add_to_wishlist_button_exclude_products' ) ) {
	function yith_wcwl_show_add_to_wishlist_button_exclude_products( $show ) {
		global $product;

        $product_id = $product->get_id();

		$excluded_products_id = array(
			'id-1',
                        'id-2',
		);

		if ( in_array( $product_id, $excluded_products_id ) ) {
            return false;
        }

		return $show;
	}
	add_filter( 'yith_wcwl_show_add_to_wishlist', 'yith_wcwl_show_add_to_wishlist_button_exclude_products', 10, 1 );
}
