根据我之前的问题,以下是Display a product custom field only in WooCommerce Admin single orders的回答:
- 添加自定义SKU字段(ArticleID)
- 将自定义SKU(ArticleID)保存为隐藏订单项元数据
- 将自定义SKU(ArticleID)保存为手动订单的隐藏订单项元数据
然而,最后一个部分(针对手动订单)似乎与我添加的其他自定义代码(用于网关费用)冲突:
// Assign Card Gateway Percentage Fee to Wholesaler Profiles
add_action('woocommerce_cart_calculate_fees', 'sm_credit_card_fee_role_gateway' );
function sm_credit_card_fee_role_gateway( $cart ){
if ( is_admin() && !defined('DOING_AJAX') )
return;
// Only on checkout page and logged in users
if ( ! ( is_checkout() && ! is_wc_endpoint_url() ) || ! is_user_logged_in() )
return;
$wpuser_object = wp_get_current_user();
$allowed_roles = array('administrator', 'default_wholesaler', 'wholesaler-non-vat-registered', 'wholesaler-ex-vat-registered', 'wholesaler-ex-non-vat-registered', 'shop_manager');
if ( array_intersect($allowed_roles, $wpuser_object->roles) ){
$payment_method = WC()->session->get('chosen_payment_method');
if ( 'cardgatecreditcard' === $payment_method ){
$percentage = 8.25;
$description = 'Credit Card';
}
elseif ( 'cardgatesofortbanking' === $payment_method ){
$percentage = 6;
$description = 'SofortBanking';
}
elseif ( 'cardgategiropay' === $payment_method ){
$percentage = 3.15;
$description = 'GiroPay';
}
elseif ( 'cardgateideal' === $payment_method ){
$percentage = 2.1;
$description = 'iDEAL';
}
}
if ( isset($percentage) ) {
$surcharge = ($cart->cart_contents_total + $cart->shipping_total) * $percentage / 100;
$cart->add_fee( sprintf( __('%s Fee (%s)', 'woocommerce'), $description, $percentage . '%' ), $surcharge, true );
}
}
当我尝试更新或更改应用网关费用的订单状态时,出现致命错误:
因此,要么我的SKU代码的第三部分需要编写得更好,要么我的网关费用代码需要更新。我该如何进一步解决问题?
这是致命错误:

第920行代码是“将SKU“ArticleID”保存为手动订单隐藏订单项目元数据”的一部分。
$product = $item->get_product(); // Get the WC_Product Object
