由於贈品我是用比較笨的方式，用0元商品，因此還要搭配下面的functoin使用
禁止贈品被搜尋
function exclude_gift_products_from_search1111($query) {

return $query;

若產品名稱有'贈品'均返回首頁
function check_product_name_and_redirect() {
if (is_product()) {
global $post;
$product_name = $post->post_title;
if (strpos($product_name, '贈品') !== false) {
wp_redirect(home_url());
exit();
}
}
}
add_action('template_redirect', 'check_product_name_and_redirect');
產品有贈品兩個字無法被購買
function restrict_specific_products_from_cart2($passed, $product_id, $quantity) {
$product = wc_get_product($product_id);
if (strpos($product->get_name(), '贈品') !== false) {
$passed = false;
$message = "本商品無法加入購物車。";
wc_add_notice($message, 'error');
}
return $passed;
