在购物车中插入自定义总计行并在Woocommerce中结帐总计

在woocommerce中,我已成功设法为Woocommerce简单产品添加自定义字段,并在产品页面的其他信息标签上显示该值。

现在我完全迷失了我的拼图的最后一块,试图在购物车和结帐页面中插入一行总计算量。

自定义字段用于将体积存储在家具物品的m3中。当客户将项目添加到购物篮时,我想通过将所有自定义字段的值一起添加并在页面上向客户显示总计来计算出货的总m3。任何人都可以指出我正确的方向如何添加这些自定义字段并显示它们。

到目前为止,我的代码看起来像这样

    // Display Fields using WooCommerce Action Hook
add_action( 'woocommerce_product_options_general_product_data', 'woocom_general_product_data_custom_field' );

function woocom_general_product_data_custom_field() {
  // Create a custom text field


  // Number Field
  woocommerce_wp_text_input( 
    array( 
      'id' => '_item_volume', 
      'label' => __( 'Item Shipping Volume', 'woocommerce' ), 
      'placeholder' => '', 
      'description' => __( 'Enter the volume her in m3.', 'woocommerce' ),
      'type' => 'number', 
      'custom_attributes' => array(
         'step' => 'any',
         'min' => '0.001'
      ) 
    )
  );

}

// Hook to save the data value from the custom fields
add_action( 'woocommerce_process_product_meta', 'woocom_save_general_proddata_custom_field' );

/** Hook callback function to save custom fields information */
function woocom_save_general_proddata_custom_field( $post_id ) {

  // Save Number Field
  $number_field = $_POST['_item_volume'];
  if( ! empty( $number_field ) ) {
     update_post_meta( $post_id, '_item_volume', esc_attr( $number_field ) );
  }

}

add_action( 'woocommerce_product_additional_information', 'custom_data_in_product_add_info_tab', 20, 1 );
function custom_data_in_product_add_info_tab( $product ) {

    //Product ID - WooCommerce compatibility
    $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

    // Get your custom fields data
    $custom_field1 = get_post_meta( $product_id, '_item_volume', true );


    // Set your custom fields labels (or names)
    $label1 = __( 'Shipping Volume m3', 'woocommerce');


    // The Output
    echo '<h3>'. __('Item Shipping Volume', 'woocommerce') .'</h3>
    <table class="custom-fields-data">
        <tbody>
            <tr class="custom-field1">
                <th>'. $label1 .'</th>
                <td>'. $custom_field1 .'</td>
            </tr>
        </tbody>
    </table>';
}

以下内容将显示购物车和结帐页面中的购物车总量:

add_action( 'woocommerce_cart_totals_before_shipping', 'display_cart_volume_total', 20 );
add_action( 'woocommerce_review_order_before_shipping', 'display_cart_volume_total', 20 );
function display_cart_volume_total() {
    $total_volume = 0;

    // Loop through cart items and calculate total volume
    foreach( WC()->cart->get_cart() as $cart_item ){
        $product_volume = (float) get_post_meta( $cart_item['product_id'], '_item_volume', true );
        $total_volume  += $product_volume * $cart_item['quantity'];
    }

    if( $total_volume > 0 ){

        // The Output
        echo ' <tr class="cart-total-volume">
            <th>' . __( "Total Shipping Volume", "woocommerce" ) . '</th>
            <td data-title="total-volume">' . number_format($total_volume, 2) . ' m3</td>
        </tr>';
    }
}

代码进入活动子主题(或活动主题)的function.php文件。经过测试并正常工作。
