按照 Display a product custom field only in WooCommerce Admin single orders 对我上一个问题的回答,其中:
但是,似乎最后一部分(对于手动订单)与我为网关费用添加的其他自定义代码引起了冲突:
// 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了网关费用的订单的状态时,我收到此致命错误:
所以要么我的 SKU 代码的第 3 部分需要更好地编写,要么我的网关费用代码需要更新。我该如何进一步解决此问题?
这是致命错误:

第 920 行是“将 SKU“ArticleID”保存为手动订单的隐藏订单项元数据的一部分:
$product = $item->get_product(); // Get the WC_Product Object
答案 0 :(得分:2)
您只需要在最后一个函数中定位订单项,方法如下:
add_action( 'woocommerce_before_save_order_item', 'action_before_save_order_item_callback' );
function action_before_save_order_item_callback( $item ) {
// Targeting only order item type "line_item"
if ( $item->get_type() !== 'line_item' )
return; // exit
$articleid = $item->get_meta('articleid');
if ( ! $articleid ) {
$product = $item->get_product(); // Get the WC_Product Object
// Get custom meta data from the product
$articleid = $product->get_meta('articleid');
// For product variations when the "articleid" is not defined
if ( ! $articleid && $item->get_variation_id() > 0 ) {
$product = wc_get_product( $item->get_product_id() ); // Get the parent variable product
$articleid = $product->get_meta( 'articleid' ); // Get parent product "articleid"
}
// Save it as custom order item (if defined for the product)
if ( $articleid ) {
$item->update_meta_data( '_articleid', $articleid );
}
}
}
代码位于活动子主题(或活动主题)的functions.php 文件中。现在应该可以使用了。
