ecshop后台添加虚拟销量以及前台显示销量

1.在sq执行语句

ALTER TABLE `ecs_goods` ADD `sales_volume_base` INT( 10 ) UNSIGNED NOT NULL DEFAULT '0'

INSERT INTO `ecs_shop_config` (`parent_id`, `code`, `type`, `store_range`, `store_dir`, `value`, `sort_order` ) VALUES ('7','show_goods_sales', 'select', '1,0', '', '1', '1');

INSERT INTO `ecs_shop_config` (`parent_id`, `code`, `type`, `store_range`, `store_dir`, `value`, `sort_order` ) VALUES ('3', 'show_sales_type', 'select', '1,0', '', '1', '1');

注意：如果你的数据表前缀不是‘ecs_’ 请自行修改

2./admin/includes/lib_goods.php中

        $sql = "SELECT goods_id, goods_name, goods_type, goods_sn, shop_price, is_on_sale, is_best, is_new, is_hot, sort_order, goods_number, integral, " .
                    " (promote_price > 0 AND promote_start_date <= '$today' AND promote_end_date >= '$today') AS is_promote ".
                    " FROM " . $GLOBALS['ecs']->table('goods') . " AS g WHERE is_delete='$is_delete' $where" .
                    " ORDER BY $filter[sort_by] $filter[sort_order] ".
                    " LIMIT " . $filter['start'] . ",$filter[page_size]";

修改为

        $sql = "SELECT goods_id, goods_name, goods_type, goods_sn, shop_price, is_on_sale, is_best, is_new, is_hot, sort_order, goods_number, integral, sales_volume_base, " . 
                    " (promote_price > 0 AND promote_start_date <= '$today' AND promote_end_date >= '$today') AS is_promote ".
                    " FROM " . $GLOBALS['ecs']->table('goods') . " AS g WHERE is_delete='$is_delete' $where" .
                    " ORDER BY $filter[sort_by] $filter[sort_order] ".
                    " LIMIT " . $filter['start'] . ",$filter[page_size]";

3./admin/templates/goods_list.htm，在

    {if $use_storage}
    {$lang.goods_number}{$sort_goods_number}
    {/if}

后，添加

{$lang.sales_volume_base}{$sort_sales_volume_base}

在

    {if $use_storage}
    {$goods.goods_number}
    {/if}

后，添加

{$goods.sales_volume_base}

4./admin/goods.php，在

/**
 * 列表链接
 * @param   bool    $is_add         是否添加（插入）
 * @param   string  $extension_code 虚拟商品扩展代码，实体商品为空
 * @return  array('href' => $href, 'text' => $text)
 */
function list_link($is_add = true, $extension_code = '')

前，添加

/*------------------------------------------------------ */
//-- 修改商品虚拟销量
/*------------------------------------------------------ */
elseif ($_REQUEST['act'] == 'edit_sales_volume_base')
{
    check_authz_json('goods_manage');

    $goods_id = intval($_POST['id']);
    $sales_volume_base = json_str_iconv(trim($_POST['val']));

    if ($exc->edit("sales_volume_base = '$sales_volume_base', last_update=" .gmtime(), $goods_id))
    {
        clear_cache_files();
        make_json_result(stripslashes($sales_volume_base));
    }
}

5.goods.php，在

$smarty->assign('categories',         get_categories_tree($goods['cat_id']));  // 分类树

后，添加

$smarty->assign('sales_count',        get_sales_count($goods_id));

在末尾添加

/* 商品累计销量带自定义_新增加 */
function get_sales_count($goods_id)
{
    /* 查询该商品的自定义销量 */
    $sales_base = $GLOBALS['db']->getOne('SELECT sales_volume_base FROM '.$GLOBALS['ecs']->table('goods').' WHERE goods_id = '.$goods_id);
    /* 查询该商品的实际销量 */
    $sql = 'SELECT IFNULL(SUM(g.goods_number), 0) ' .
        'FROM ' . $GLOBALS['ecs']->table('order_info') . ' AS o, ' .
            $GLOBALS['ecs']->table('order_goods') . ' AS g ' .
        "WHERE o.order_id = g.order_id " .
        "AND o.order_status " . db_create_in(array(OS_CONFIRMED, OS_SPLITED)) .
        "AND o.shipping_status " . db_create_in(array(SS_SHIPPED, SS_RECEIVED)) .
        " AND o.pay_status " . db_create_in(array(PS_PAYED, PS_PAYING)) .
        " AND g.goods_id = '$goods_id'";
    $sales_count = $GLOBALS['db']->getOne($sql);
    /* 商品累计销量默认显示方式 */
    if ($GLOBALS['_CFG']['show_sales_type'])
    {
        $row['sales_volume_total'] =  $sales_count; //实际销量
    }
    else
    {
        $row['sales_volume_total'] =  $sales_base + $sales_count; //自定义销量+实际销量
    }
    return ($row['sales_volume_total']);
}

6.在/languages/zh_cn/admin/shop_config.php，中

/languages/zh_cn/admin/shop_config.php

下，添加

$_LANG['cfg_name']['show_goods_sales'] = '是否显示商品累计销量';
$_LANG['cfg_range']['show_goods_sales']['1'] = '显示';
$_LANG['cfg_range']['show_goods_sales']['0'] = '不显示';
$_LANG['cfg_name']['show_sales_type'] = '商品累计销量默认显示方式';
$_LANG['cfg_range']['show_sales_type'][1] = '真实显示';
$_LANG['cfg_range']['show_sales_type'][0] = '虚拟显示';

7./languages/zh_cn/admin/goods.php，中

$_LANG['goods_sn_exists'] = '您输入的货号已存在，请换一个';

后，添加

$_LANG['sales_volume_base'] = '虚拟销量';

8./languages/zh_cn/common.php，中

$_LANG['divided_into'] = '分成规则';

后，添加

$_LANG['sales_volume_total'] = '累计销量：'; 
$_LANG['pcs'] = '件';

9./themes/default/goods.dwt，在

后，添加

{if $cfg.show_goods_sales}

{$lang.sales_volume_total}
{$sales_count}{if $goods.measure_unit}{$goods.measure_unit}{else}{$lang.pcs}{/if}

{/if}

OK，完成！
