从订单 table 后添加的自定义行中保存值并将其显示在 WooCommerce 订单和电子邮件中

Save value from a custom row added after the order table and display it in WooCommerce orders and emails

我编写的这段代码在 WooCommerce 结账页面上显示了个性化信息。

add_action( 'woocommerce_cart_totals_after_order_total', 'show_total_discount_cart_checkout', 9999 );
add_action( 'woocommerce_review_order_after_order_total', 'show_total_discount_cart_checkout', 9999 );
 
function show_total_discount_cart_checkout() {
    
   $discount_total = 0;
    
    
   foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {     
   $product = $cart_item['data'];
       
   $subtotal = WC()->cart->get_product_subtotal( $product, $cart_item['quantity'] );
        
   $total = WC()->cart->total;
   $pctm = 90.00;
   $valor_descontado = $total - ($total / 100 * $pctm); 
        
   $sale_price = '10%'; 
   $discount = ( WC()->cart->total - $valor_descontado );
   $discount_total = $discount;
   
}                
    if ( $discount_total > 0 ) {
      echo '<tr><th>VOCÊ RECEBERÁ DE CASHBACK:</th><td data-title="You">' . wc_price( $discount_total + WC()->cart->get_discount_total() ) .'</td></tr>';
    }
  
} 

结果:


我需要此信息也显示在 WooCommerce 订单和电子邮件中。我相信我自己可以想出一个解决方案来在其他几个页面上显示这个值,但是有人可以先告诉我如何 save/store 这个计算的值吗?

首先,我重写了您现有的代码,原因如下:

  • 请求小计和总计最好在foreach循环之外完成,否则这些值每次都会被覆盖
  • $subtotal 的结果没有在您的代码中的任何地方使用
  • 由于 $subtotal 的结果无论如何都没有被使用,循环遍历购物车似乎是不必要的
  • $sale_price 也没有在您的代码中的任何地方使用
  • 因为$discount_total = $discount没有必要使用新变量
  • 一个会话变量是created/added

您现有的代码,但已优化:

function action_woocommerce_after_order_total() {
    // WC Cart NOT null
    if ( ! is_null( WC()->cart ) ) {
        // Get cart
        $cart = WC()->cart;
        
        // Getters
        $cart_total = $cart->total;
        $cart_discount_total = $cart->get_discount_total();
        
        // Settings
        $pctm = 90;
        
        // Calculations
        $discounted_value = $cart_total - ( $cart_total / 100 * $pctm );
        $discount_total = $cart_total - $discounted_value;
        
        // Greater than
        if ( $discount_total > 0 ) {
            // Result
            $result = $discount_total + $cart_discount_total;
            
            // The Output
            echo '<tr class="my-class">
                    <th>' . __( 'VOCÊ RECEBERÁ DE CASHBACK', 'woocommerce' ) . '</th>
                    <td data-title="You">' . wc_price( $result ) . '</td>
                  </tr>';
            
            // Set session
            WC()->session->set( 'session_result', $result );
        }
    }
}
add_action( 'woocommerce_cart_totals_after_order_total', 'action_woocommerce_after_order_total', 10 );
add_action( 'woocommerce_review_order_after_order_total', 'action_woocommerce_after_order_total', 10 );

回答你的问题:

步骤 1) 我们从会话变量中获取结果并将其添加为订单数据,这样我们就可以 use/obtain 通过 $order对象

// Add as custom order meta data and reset WC Session variable
function action_woocommerce_checkout_create_order( $order, $data ) {    
    // Isset
    if ( WC()->session->__isset( 'session_result' ) ) {
        // Get
        $result = (float) WC()->session->get( 'session_result' );
        
        // Add as meta data
        $order->update_meta_data( 'result', $result );
        
        // Unset
        WC()->session->__unset( 'session_result' );
    }
}
add_action( 'woocommerce_checkout_create_order', 'action_woocommerce_checkout_create_order', 10, 2 );

步骤 2) 使用 woocommerce_get_order_item_totals 过滤器挂钩,这将允许您使用 $result 向现有表添加新行。

新行将添加到:

  • 电子邮件通知
  • 收到订单(感谢页面)
  • 我的账户 -> 查看订单
function filter_woocommerce_get_order_item_totals( $total_rows, $order, $tax_display ) {    
    // Get meta
    $result = $order->get_meta( 'result' );
    
    // NOT empty
    if ( ! empty ( $result ) ) {
        // Add new row
        $total_rows['total_result']['label'] = __( 'VOCÊ RECEBERÁ DE CASHBACK', 'woocommerce' );
        $total_rows['total_result']['value'] = wc_price( $result );
    }

    return $total_rows;
}
add_filter( 'woocommerce_get_order_item_totals', 'filter_woocommerce_get_order_item_totals', 10, 3 );
