使用做网站时，有个苦恼，就是推广前期，商城销量很少，要是能够显示一个假的销量就好了。
通过本教程就可以实现。
教程开始
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') 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') 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 $use_storage}
{$sort_goods_number}
{/if}
后，添加
{$sort_sales_volume_base}
在
{if $use_storage}
[td]{$goods.goods_number}[/td]
{/if}
后，添加
[td]{$goods.sales_volume_base}[/td]
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！
