Php Woocommerce错误ET_WC_Order:：get_total（）

我在WoodPress主题中使用Woocommerce。该网站正在出售服务。模板开发者的支持已经死了，他们说是商业兼容性，但是有一个小错误，我需要自己找到修复，但我不知道该怎么做

当客户尝试向其帐户添加信用时，他选择该值并进入下一个屏幕，其中显示了woocommerce支付网关，它们被列出，但“支付”按钮不在那里。当我查看Wordpress wp内容调试日志时，我发现以下错误：

PHP严格标准：声明ET_WC_Order:：get_total（）应该
与WC_Abstract_Order:：get_total（$context='view'）兼容

将
ET\u WC\u Order.php
中的
get\u total（）
函数更改为

public function get_total($context = 'view')
{
    $orderData = $this->etOrder->get_order_data();
    $total = $orderData["total"];
    return $total;
}

public function get_sku($context = 'view')
{
    return $this->post->ID;
}

PHP严格标准：声明ET_WC_包：：get_sku（）应该
与WC_产品兼容：：获取_sku（$context='view'）

将
ET\u WC\u Package.php
中的
get\u sku（）
函数更改为

public function get_total($context = 'view')
{
    $orderData = $this->etOrder->get_order_data();
    $total = $orderData["total"];

谢谢你，我亲爱的朋友。这解决了我所有的问题。
