}

上面是为WooCommerce / Wordpress的6层定价系统创建的代码。 当仅创建了一个新的带有角色关联的定价层时，简单产品就可以正常工作，并且在添加全部6个产品之前，该代码也适用于变体产品。

我很难找到代码中的问题，但它仍然适用于简单的产品； 但是同样无法加载版本产品的产品页面，也无法在后端显示每个版本所节省的价格。

任何帮助将不胜感激！

此外，日志文件中没有任何内容作为错误生成。

谢谢，

约书亚记

好像您缺少一个函数sfprice_corporate_applicable()

在您的脚本中，您尝试访问该功能，但是您的项目中不存在该功能。

所以像这样创建新功能 

function sfprice_corporate_applicable() {
    return (bool) ( current_user_can('corporate') && ( !is_admin() || is_ajax() ) );
}
