PHP 已弃用：不推荐创建动态属性 WPSC_Cart：：$log_id

问：

在修复了一些动态属性弃用警告后，刚刚升级到 PHP 8.2。

以为一切都已得到解决，升级后从错误日志中发现了一个剩余的问题，正在努力修复。

对php来说仍然很新，所以可能是我错过了一些明显的东西。

我苦苦挣扎的原因是因为该文件中的任何 php 代码中都没有提到类，它与所有其他动态属性警告一起出现在函数的正上方，可以通过添加例如：

public $log_id;

与此错误相关的代码如下：

function wpsc_submit_checkout( $collected_data = true ) {
global $wpdb, $wpsc_cart, $user_ID, $nzshpcrt_gateways, $wpsc_shipping_modules, $wpsc_gateways;

// checkout is falid, until we find a reason otherwise

}

这是与上述错误相关的代码行：

    $wpsc_cart->log_id = $purchase_log_id;

任何帮助或建议将不胜感激！
