Ecstore/BBC 导出虚拟表数据

需求场景：导出待发货订单，数据要求如下：

分析：数据中是主订单和子订单两张表的混合数据，不能影响原有的订单导出

步骤：
一、新建model：

• custom/systrade/model/tradeorder.php

<?php
class systrade_mdl_tradeorder{

    var $defaultOrder = array('tid','DESC');
    
    public $schema = array();

    public function __construct() {
        $this->app->app_id = 'systrade';
        $this->schema = app::get('systrade')->model('trade')->get_schema();
    }

    public function _columns(){
        return app::get('systrade')->model('order')->_columns();
    }

    public function getList( $cols='*', $filter=array(), $offset=0, $limit=-1, $orderType=null )
    {
        $filter['status'] = 'WAIT_SELLER_SEND_GOODS';
        return app::get('systrade')->model('order')->getList( $cols, $filter, $offset, $limit, $orderType );
    }

}

ps: model不要继承，否则找不到dbschema会报错

二、新建扩展类

• custom/importexport/lib/data/trade/tradeorder.php

<?php
/**
 * trade.php
 *
 * @copyright  Copyright (c) 2005-2015 ShopEx Technologies Inc. (http://www.shopex.cn)
 * @license  http://ecos.shopex.cn/ ShopEx License
 */
class importexport_data_trade_tradeorder {

     // 设置标题
    public function get_title()
    {
        $fields = 'oid,tid,pay_time,title,spec_nature_info,num,bn,price,payment';
        $fields = explode(',', $fields);
        $tmpTitle = $this->_title();
        $title = array();
        foreach ($fields as $val)
        {
            if(array_key_exists($val, $tmpTitle))
            {
                $title[$val] = $tmpTitle[$val];
            }
        }
        if(!$title)
        {
            $title = $tmpTitle;
        }
        $title['status'] = app::get('importexport')->_('订单状态');
        $title['total_fee'] = app::get('importexport')->_('邮费');
        $title['created_time'] = app::get('importexport')->_('订单创建时间');
        $title['receiver_name'] = app::get('importexport')->_('收货人');
        $title['receiver_mobile'] = app::get('importexport')->_('联系电话');
        $title['receiver_state'] = app::get('importexport')->_('收货人所在省');
        $title['receiver_city'] = app::get('importexport')->_('收货人所在市');
        $title['receiver_district'] = app::get('importexport')->_('收货人所在区');
        $title['receiver_address'] = app::get('importexport')->_('收货地址');
        $title['buyer_message'] = app::get('importexport')->_('买家备注');

        return $title;
    }

    private function _title()
    {
        $cols = app::get('systrade')->model('order')->_columns();
        $title = array();
        foreach( $cols as $col => $val )
        {
            if( !$val['deny_export'] ){//不进行导出导入字段
                if(!$val['label'] && !$val['comment'])
                {
                    $title[$col] = $col;
                }
                else
                {
                    $title[$col] = $val['label'] ? $val['label'] : $val['comment'];
                }
            }
        }
        return $title;
    }

    public function get_content_row($row)
    {
        $objMdlTrade = app::get('systrade')->model('trade');
        $result = $objMdlTrade->getRow('created_time,status,total_fee,receiver_name,receiver_mobile,receiver_state,receiver_city,receiver_district,receiver_address,buyer_message', array('tid'=>$row['tid']));

        $row['status'] = $result['status'];
        $row['total_fee'] = $result['total_fee'];
        $row['created_time'] = $result['created_time'];
        $row['receiver_name'] = $result['receiver_name'];
        $row['receiver_mobile'] = $result['receiver_mobile'];
        $row['receiver_state'] = $result['receiver_state'];
        $row['receiver_city'] = $result['receiver_city'];
        $row['receiver_district'] = $result['receiver_district'];
        $row['receiver_address'] = $result['receiver_address'];
        $row['buyer_message'] = $result['buyer_message'];

        return $row;
    }
}

三、注册service

• custom/importexport/services.xml 添加一下代码

    <service id="importexport.systrade_mdl_tradeorder">
        <class>importexport_data_trade_tradeorder</class>
    </service>

ps:services.xml中class与扩展类名一致

四、添加权限

• custom/topshop/controller/export.php
  

   ps:BBC商家端订单导出需要，其他地方视情况而定
  

开发过程中遇到一个现象奇怪的问题：数据写入文件时写不进去，原因是下面的if条件不成立，对比两者数据发现是数组的键值顺序不一样，例如：created_time在title中在第九个位置，数据中 循环是created_time在第12个位置，造成原因不明，后来在扩展类中将数据顺序调整之后导出才可以。。
