在 WooCommerce 4 中设置购物车过期间隔

Question

那么，我如何在 woocommerce 中过期并清空购物车，因为过滤器根本不这样做，只会在给定的几分钟内增加会话，老实说，我不知道到底在哪里使用或是否以任何方式清除购物车？

有这个：

    add_filter( 'wc_session_expiring', 'wc_custom_session_expiring' );
    add_filter( 'wc_session_expiration', 'wc_custom_session_expiring' );

    function wc_custom_session_expiring( $expiry ) {
        return 300; // 5 mins in seconds
    }

Answer 1

下面，你有我为客户编写的代码，只是为了节省你们一些时间，如果“延迟”给定时间没有过去，这里发布的代码会更新过期时间，并且用户仍然活跃/在商店买东西。如果用户停止点击页面超过 5 分钟（您可以更改代码），他在商店中的下一次点击，或下一个加载的页面，购物车将被清空。

我正在使用 ReflectionClass 从会话类中快速读取一些受保护的值，就在过滤器的帮助下更新过期值之后。

请注意此插件使用$_SESSION，请随意修改并在此处发布您自己的版本！ 请注意这一点：$minutes = get_option( 'expire_option', '5' );，我为此使用了管理表单字段（选项）设置，请随意添加您自己的。
