Question

型号

$sql = "
SELECT  op.name 
     , op.price 
     , op.quantity 
     , o.order_cancel_remark  
  FROM order_product op 
  LEFT 
  JOIN `order` o 
    ON o.order_id = op.order_id 
  LEFT 
  JOIN `order_product_history` oph 
    ON oph.`order_product_id` = op.`order_product_id` 
   AND oph.`current_status` = 1 
  LEFT 
  JOIN `order_status` os 
    ON os.`order_status_id` = oph.`order_status_id` 
   AND os.`language_id` = 1 
 WHERE o.order_id = '" . (int)$order_id . "'";

$query = $this->db->query($sql);

return $query->rows;

控制器

    $data['orderP_results'][] = array(

        'name'      => $order_price_result['name'] ,
        'price'     => number_format($order_price_result['map'],2,'.',''),
        'quantity'  => $order_price_result['quantity'],
        'sku'       => $order_price_result['sku'],
         'order_cancel_remark'      => $order_price_result['order_cancel_remark'],
        'total'     => number_format($order_price_result['map'] * $order_price_result['quantity'],2,'.',''),

我想要的："Order Cancel Remark" 只显示 1 次而不是多次（取决于行数）

Answer 1

在您看来，从 for 循环中删除 order_cancel_remark 并将其添加到外部以仅显示一次

{% if orderP_results %}
            {{orderP_result[0].order_cancel_remark}}
            {% for orderP_result in orderP_results %}
            <table class="d">
            <tr>
                <th>        <legend style="padding-top:10px;">Product Image</legend></th>
                <th>    <legend style="padding-top:10px;">Product Name</legend></th>
                <th>        <legend style="padding-top:10px;">Product SKU</legend></th>
            </tr>
            <tr>
                <td>    <img src="{{orderP_result.image}}"></td>
                    <td>    <b class="color-bold">{{orderP_result.name}}</b> </td>
                        <td>        SKU: <b class="color-bold">{{orderP_result.sku}}</b></td>
            </tr>
        </table>

Answer 2

仅供参考，您的查询在功能上与以下内容相同：

SELECT  op.name 
 , op.price 
 , op.quantity 
 , o.order_cancel_remark  
  FROM order_product op  
  JOIN `order` o 
    ON o.order_id = op.order_id 
  WHERE o.order_id = '" . (int)$order_id . "'";
