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 $use_storage}   <th><a href=”javascript:listTable.sort(‘goods_number’); “>{$lang.goods_number}</a>{$sort_goods_number}</th>   {/if}   后，添加   <th><a href=”javascript:listTable.sort(‘sales_volume_base’);

  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);

  后，添加   $_LANG[‘sales_volume_total’] = ‘累计销量：’;    $_LANG[‘pcs’] = ‘件’;     9./themes/default/goods.dwt，在   <img src=”images/stars{$goods.comment_rank}.gif” alt=”comment rank {$goods.comment_rank}” />    </dd>   后，添加   {if $cfg.show_goods_sales}   <dd style=”width:48%; padding-left:7px;”>   <strong>{$lang.sales_volume_total}</strong>   <font class=”shop”>{$sales_count}{if $goods.measure_unit}{$goods.measure_unit}{else}{$lang.pcs}{/if}</font>   </dd>   {/if}   OK，完成！
