我正在尝试添加＆＃34;运营商＆＃34;列到订单表。我知道我需要在AdminOrdersController.php中的fields_list数组中添加该字段，但是当我在字段carrier上展开数组时，我在BO中出现unknown column 'carrier'错误。我做错了什么？
答案 0 :(得分：3)
您应该修改$ this-＆gt; _select，$ this-＆gt; _join和$ this-＆gt; field_list变量以显示运营商。
$ this-＆gt; _join应包含以下内容
LEFT JOIN `'._DB_PREFIX_.'order_carrier` oc ON (a.`id_order` = oc.`id_order`)
LEFT JOIN `'._DB_PREFIX_.'carrier` carr ON (oc.`id_carrier` = carr.`id_carrier`)
然后，在select中你有了carr表，所以你可以使用
carr.name as `carriername`
检索承运人。然后，在字段列表中，您应该使用类似
的内容'carriername' => array(
'title' => $this->l('Carrier')
),
请注意前两个项应该是有效的SQL，因此请在正确的位置使用空格和逗号（取决于您添加代码的位置）。此外，您应该使用覆盖功能，因此您仍然可以获得Prestashop更新（请参阅http://doc.prestashop.com/display/PS16/Overriding+default+behaviors#Overridingdefaultbehaviors-Overridingacontroller）。

有点迟，因为Markus会指导你如何做到这一点。我测试了这个覆盖。
在override/controllers/admin中使用以下代码创建新文件AdminOrdersController.php：
<?php
class AdminOrdersController extends AdminOrdersControllerCore
{
public function __construct()

$this->bootstrap = true;
$this->table = 'order';
$this->className = 'Order';

$this->deleted = false;
$this->context = Context::getContext();
$this->_select = '

if (Country::isCurrentlyUsed('country', true)) {
$result = Db::getInstance(_PS_USE_SQL_SLAVE_)->ExecuteS('

$part1['cname'] = array(

$this->shopLinkType = 'shop';

if (Tools::isSubmit('id_order')) {
// Save context (in order to apply cart rule)
$order = new Order((int)Tools::getValue('id_order'));
$this->context->cart = new Cart($order->id_cart);
$this->context->customer = new Customer($order->id_customer);
}
$this->bulk_actions = array(
'updateOrderStatus' => array('text' => $this->l('Change Order Status'), 'icon' => 'icon-refresh')

AdminController::__construct();
}
}
与Markus explainnantion相同，我已加入carrier表，然后在查询中选择添加的名称（已设置显示 - 如果没有运营商）并在field_list中显示工作过滤器和顺序。
请注意，在此覆盖中，您无需调用parent::__construct();，而是AdminController::__construct();。
如果需要，还要清除PrestaShop缓存。
