php - 如何仅跳过某些产品的 woocommerce 购物车页面？

Question

我将此添加到我的functions.php文件中:

add_filter ('woocommerce_add_to_cart_redirect', 'woo_redirect_to_checkout');
function woo_redirect_to_checkout() {
$checkout_url = WC()->cart->get_checkout_url();
return $checkout_url;
}

但现在，所有的产品都在重新引导海峡结账。我只想在一种产品中使用此选项。这是我可以向同一个文件管理器添加产品 ID 的方法吗？

谢谢!

Answer 1

我为此写了一个小插件，在这里分享。该插件向产品元框添加了一个小复选框，因此您可以指定哪些产品应触发自动跳转到结帐。基本使用相同 woocommerce_add_to_cart_redirect像其他答案一样过滤，但提供管理后端选项来确定哪些产品触发重定向。
