将产品重量和尺寸添加为WooCommerce管理手册订单上的订单项元数据

Question

基于将产品自定义字段保存为自定义订单项元数据的WooCommerce管理手动订单

我有这些代码来显示从前端下的订单的产品重量和尺寸，但我无法让它们用于从后端手动下的订单。当我添加产品时，我看不到重量和尺寸，它们也不会显示在页面上以支付订单、收到订单和发送电子邮件。

这是我的代码：

在任何地方展示并保存产品的重量。

// Display the cart item weight in cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'display_custom_item_data', 10, 2 );
function display_custom_item_data( $cart_item_data, $cart_item ) {
    if ( $cart_item['data']->get_weight() > 0 ){
        $cart_item_data[] = array(
            'name' => __( 'Weight', 'woocommerce' ),
            'value' =>  $cart_item['data']->get_weight()  . ' ' . get_option('woocommerce_weight_unit')
        );
    }
    return $cart_item_data;
}

// Save and Display the order item weight (everywhere)
add_action( 'woocommerce_checkout_create_order_line_item', 'display_order_item_data', 20, 4 );
function display_order_item_data( $item, $cart_item_key, $values, $order ) {
    if ( $values['data']->get_weight() > 0 ){
        $item->update_meta_data( __( 'Weight', 'woocommerce' ), $values['data']->get_weight()  . ' ' . get_option('woocommerce_weight_unit') );
    }
}

到处显示和保存产品尺寸。

// Display the cart item weight in dimensions and checkout pages
add_filter( 'woocommerce_get_item_data', 'display_custom_item_data1', 10, 2 );
function display_custom_item_data1( $cart_item_data, $cart_item ) {
    if ( $cart_item['data']->has_dimensions() > 0 ){
        $cart_item_data[] = array(
            'name' => __( 'Dimensions', 'woocommerce' ),
            'value' =>  $cart_item['data']->get_dimensions()  . ' ' . get_option('woocommerce_dimensions_unit')
        );
    }
    return $cart_item_data;
}

// Save and Display the order item dimensions (everywhere)
add_action( 'woocommerce_checkout_create_order_line_item', 'display_order_item_data1', 20, 4 );
function display_order_item_data1( $item, $cart_item_key, $values, $order ) {
    if ( $values['data']->has_dimensions() > 0 ){
        $item->update_meta_data( __( 'Dimensions', 'woocommerce' ), $values['data']->get_dimensions()  . ' ' . get_option('woocommerce_dimensions_unit') );
    }
}

add_filter( 'woocommerce_format_dimensions', 'custom_formated_product_dimentions', 10, 2 );
function custom_formated_product_dimentions( $dimension_string, $dimensions ){
    $text_domain    = 'woocommerce';
    $dimension_unit = get_option('woocommerce_dimensions_unit');

    if ( empty( $dimension_string ) )
        return __( 'N/A', $text_domain );

    // Set here your new array of dimensions based on existing keys/values
    $new_dimentions = array(
        __('Largo:', $text_domain)    => $dimensions['length'],
        __('Ancho:', $text_domain) => $dimensions['width'],
        __('Alto:', $text_domain)     => $dimensions['height'],
    );

    $dimensions = array_filter( array_map( 'wc_format_localized_decimal', $new_dimentions ) );

    foreach( $dimensions as $key => $dimention ){
        $dimensions[$key] = ucfirst($key) . ' ' . $dimention. ' ' . get_option( 'woocommerce_dimension_unit' );
    }

    return implode( ' × ',  $dimensions);
}

要将产品重量和尺寸显示为手动后端订单上的自定义订单项目元数据，您将使用woocommerce\u-before\u-save\u-order\u-item专用操作挂钩，如下所示：

add_action( 'woocommerce_before_save_order_item', 'action_before_save_order_item_callback' );
function action_before_save_order_item_callback( $item ) {
    // 1. WEIGHT
    $weight = $item->get_meta('Weight');
    // If custom meta data is not saved as order item
    if ( empty($weight) ) {
        // Get the WC_Product Object
        $product = $item->get_product();
        
        // Get custom meta data from the product
        $weight      = $product->get_weight();
        $weight_unit = get_option('woocommerce_weight_unit');

        // Save it as custom order item (if defined for the product)        
        if ( $weight ) {
            $item->update_meta_data( 'Weight', $weight . ' ' . $weight_unit );
        }
    }
    
    // 2. DIMENSIONS
    $dimensions = $item->get_meta('Dimensions');
    // If custom meta data is not saved as order item
    if ( empty($dimensions) ) {
        // Get the WC_Product Object
        $product = $item->get_product();
        
        // Get custom meta data from the product
        $dimensions = $product->get_dimensions();
        $dim_unit   = get_option('woocommerce_dimensions_unit');

        // Save it as custom order item (if defined for the product)        
        if ( $dimensions ) {
            $item->update_meta_data( 'Dimensions', $dimensions . ' ' . $dim_unit );
        }
    }
}

代码进入函数。活动子主题（或活动主题）的php文件。测试和工作。
