仅在手动订单的WooCommerce Admin单笔订单中显示产品自定义字段

分类: 技术问答 • 2022-04-15 12:08:47
问题描述：

跟随仅显示产品自定义字段在WooCommerce管理员单笔订单中回答了我之前的问题，

Following Display a product custom field only in WooCommerce Admin single orders answer to my previous question, which:

  1. 添加自定义SKU字段(ArticleID)
  2. 将自定义SKU(ArticleID)保存为隐藏订单项元数据
  3. 将自定义SKU(ArticleID)保存为手动订单的隐藏订单商品元数据

但是，似乎最后一部分(用于手动订单)与我为网关费用"添加的以下其他自定义代码产生了冲突:

However, it seems that the last part (for Manual Orders) is causing a conflict with this following other custom code I added for Gateway Fees:

// 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已应用网关费用"的订单的状态时，出现此致命错误:

When I try to update or change the status of an order that has Gateway Fees applied to it, I get this Fatal Error:

因此，我的SKU代码的第3部分需要更好地编写，或者我的网关费用代码需要更新.我该如何进一步解决此问题?

So either part 3 of my SKU code needs to be written better, or my gateway fee code needs to be updated. How do I go about troubleshooting this further?

这是致命错误:

Fatal error: Uncaught Error: Call to undefined method WC_Order_Item_Fee::get_product() in …/public_html/wp-content/themes/oceanwp-child/functions.php:920

作为保存SKU" ArticleID"的一部分的行920.作为手动订单的隐藏订单商品元数据":

The line Line 920 which is part of "Save SKU "ArticleID" as Hidden Order Item Meta Data for Manual Orders":

$product = $item->get_product(); // Get the WC_Product Object

答

您只需要将最后一个功能上的订单项定位，就这样:

You need to target only line items on the last function, this way:

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 );
        }
    }
}

代码进入活动子主题(或活动主题)的functions.php文件中.现在应该可以使用了.

Code goes in functions.php file of the active child theme (or active theme). It should works now.
