不应直接访问订单属性 - WooCommerce 3.0

Question

我刚刚将我当地的WooCommerce网站升级到3.0.一切都像平常一样完美,但我注意到打开调试后我得到了以下数百条通知:

[05-Apr-2017 12:25:00 UTC] PHP Notice: id was called <strong>incorrectly</strong>. Order properties should not be accessed directly. Please see <a href="https://codex.wordpress.org/Debugging_in_WordPress">Debugging in WordPress</a> for more information. (This message was added in version 3.0.) in C:\xampp\htdocs\dev\wp-includes\functions.php on line 4137

因此看起来WooCommerce正在退回能够直接调用订单数据.这个代码被触发的一个例子就是我的functions.php文件中的这个函数:

function eden_woocommerce_order_number($original, $order)
{
    return 'EDN-' . str_pad($order->id, 10, 0, STR_PAD_LEFT);
}

这个函数只是将"EDN"添加到订单ID的开头并填充10个字符,但是WooCommerce不喜欢我的调用$order方式 - 重写3.0这样的函数的最佳方法是什么？

Answer 1

它说"id被错误地调用.不应该直接访问订单属性."

尝试 $order->get_id()

Answer 2

也许它对其他人也有帮助.这是关于通过magic函数直接访问值的所有函数的一些内容.

此功能来自Woocommerce 3.0
