本补丁以假乱真，对网站销售有一定帮助，计算公式：前台显示销量 = 后台自定义销量 = 实际销量，以下讲解以官方默认模板(default)为例

开发指南
一、将安装文件覆盖到网站根目录（覆盖前注意备份），输入”站点路径/db_patch.php”，如”http://ecshop.phpally.com/db_patch.php”一键完成数据库补丁的安装，安装完成后，请立即删除db_patch.php。

'/includes/init.php'); 16 17 $sql = " 18 ALTER TABLE `{$prefix}goods` ADD `sales_volume_base` INT( 10 ) UNSIGNED NOT NULL DEFAULT '0' COMMENT '销量基数' 19 "; 20 $db->query($sql); 21 echo '数据库补丁程序执行成功，请立即删除此补丁文件(db_patch.php)。';
二、编辑/admin/goods.php，添加修改销量基数（sales_volume_base）
1 *------------------------------------------------------ */ 2 //-- 修改商品销量基数 3 /*------------------------------------------------------ */ 4 elseif ($_REQUEST['act'] == 'edit_sales_volume_base') 5 { 6 check_authz_json('goods_manage'); 7 8 $goods_id = intval($_POST['id']); 9 $sales_volume_base = json_str_iconv(trim($_POST['val'])); 10 11 if ($exc->edit("sales_volume_base = '$sales_volume_base', last_update=" .gmtime(), $goods_id)) 12 { 13 clear_cache_files(); 14 make_json_result(stripslashes($sales_volume_base)); 15 } 16 }
三、编辑/admin/includes/lib_goods.php，添加查询销量基数（sales_volume_base）
1 ql = "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, " . 2 " (promote_price > 0 AND promote_start_date <= '$today' AND promote_end_date >= '$today') AS is_promote ". 3 " FROM " . $GLOBALS['ecs']->table('goods') . " AS g WHERE is_delete='$is_delete' $where" . 4 " ORDER BY $filter[sort_by] $filter[sort_order] ". 5 " LIMIT " . $filter['start'] . ",$filter[page_size]";
四、编辑/admin/templates/goods_list.htm，添加显示销量基数（sales_volume_base）
1 <table cellpadding="3" cellspacing="1"> 2 <tr> 3 <th> 4 <input onclick='listTable.selectAll(this, "checkboxes")' type="checkbox" /> 5 <a href="javascript:listTable.sort('goods_id'); ">{$lang.record_id}</a>{$sort_goods_id} 6 </th> 7 <th><a href="javascript:listTable.sort('goods_name'); ">{$lang.goods_name}</a>{$sort_goods_name}</th> 8 <th><a href="javascript:listTable.sort('goods_sn'); ">{$lang.goods_sn}</a>{$sort_goods_sn}</th> 9 <th><a href="javascript:listTable.sort('shop_price'); ">{$lang.shop_price}</a>{$sort_shop_price}</th> 10 <th><a href="javascript:listTable.sort('is_on_sale'); ">{$lang.is_on_sale}</a>{$sort_is_on_sale}</th> 11 <th><a href="javascript:listTable.sort('is_best'); ">{$lang.is_best}</a>{$sort_is_best}</th> 12 <th><a href="javascript:listTable.sort('is_new'); ">{$lang.is_new}</a>{$sort_is_new}</th> 13 <th><a href="javascript:listTable.sort('is_hot'); ">{$lang.is_hot}</a>{$sort_is_hot}</th> 14 <th><a href="javascript:listTable.sort('sort_order'); ">{$lang.sort_order}</a>{$sort_sort_order}</th> 15 {if $use_storage} 16 <th><a href="javascript:listTable.sort('goods_number'); ">{$lang.goods_number}</a>{$sort_goods_number}</th> 17 {/if} 18 <th><a href="javascript:listTable.sort('sales_volume_base'); ">{$lang.sales_volume_base}</a>{$sort_sales_volume_base}</th> 19 <th>{$lang.handler}</th> 20 <tr> 21 {foreach from=$goods_list item=goods} 22 <tr> 23 <td><input type="checkbox" name="checkboxes[]" value="{$goods.goods_id}" />{$goods.goods_id}</td> 24 <td class="first-cell" style="{if $goods.is_promote}color:red;{/if}"><span onclick="listTable.edit(this, 'edit_goods_name', {$goods.goods_id})">{$goods.goods_name|escape:html}</span></td> 25 <td><span onclick="listTable.edit(this, 'edit_goods_sn', {$goods.goods_id})">{$goods.goods_sn}</span></td> 26 <td align="right"><span onclick="listTable.edit(this, 'edit_goods_price', {$goods.goods_id})">{$goods.shop_price} 27 28 </span></td> 29 <td align="center"><img src="images/{if $goods.is_on_sale}yes{else}no{/if}.gif" onclick="listTable.toggle(this, 'toggle_on_sale', {$goods.goods_id})" /></td> 30 <td align="center"><img src="images/{if $goods.is_best}yes{else}no{/if}.gif" onclick="listTable.toggle(this, 'toggle_best', {$goods.goods_id})" /></td> 31 <td align="center"><img src="images/{if $goods.is_new}yes{else}no{/if}.gif" onclick="listTable.toggle(this, 'toggle_new', {$goods.goods_id})" /></td> 32 <td align="center"><img src="images/{if $goods.is_hot}yes{else}no{/if}.gif" onclick="listTable.toggle(this, 'toggle_hot', {$goods.goods_id})" /></td> 33 <td align="center"><span onclick="listTable.edit(this, 'edit_sort_order', {$goods.goods_id})">{$goods.sort_order}</span></td> 34 {if $use_storage} 35 <td align="right"><span onclick="listTable.edit(this, 'edit_goods_number', {$goods.goods_id})">{$goods.goods_number}</span></td> 36 {/if} 37 <td align="center"><span onclick="listTable.edit(this, 'edit_sales_volume_base', {$goods.goods_id})">{$goods.sales_volume_base}</span></td> 38 <td align="center"> 39 <a href="../goods.php?id={$goods.goods_id}" target="_blank" title="{$lang.view}"><img src="images/icon_view.gif" width="16" height="16" border="0" /></a> 40 <a href="goods.php?act=edit&goods_id={$goods.goods_id}{if $code neq 'real_goods'}&extension_code={$code}{/if}" title="{$lang.edit}"><img src="images/icon_edit.gif" width="16" height="16" border="0" /></a> 41 <a href="goods.php?act=copy&goods_id={$goods.goods_id}{if $code neq 'real_goods'}&extension_code={$code}{/if}" title="{$lang.copy}"><img src="images/icon_copy.gif" width="16" height="16" border="0" /></a> 42 <a href="javascript:;" onclick="listTable.remove({$goods.goods_id}, '{$lang.trash_goods_confirm}')" title="{$lang.trash}"><img src="images/icon_trash.gif" width="16" height="16" border="0" /></a> 43 {if $specifications[$goods.goods_type] neq ''}<a href="goods.php?act=product_list&goods_id={$goods.goods_id}" title="{$lang.item_list}"><img src="images/icon_docs.gif" width="16" height="16" border="0" /></a>{else}<img src="images/empty.gif" width="16" height="16" border="0" />{/if} 44 {if $add_handler} 45 | 46 {foreach from=$add_handler item=handler} 47 <a href="{$handler.url}&goods_id={$goods.goods_id}" title="{$handler.title}"><img src="images/{$handler.img}" width="16" height="16" border="0" /></a> 48 {/foreach} 49 {/if} 50 </td> 51 </tr> 52 {foreachelse} 53 <tr><td class="no-records" colspan="10">{$lang.no_records}</td></tr> 54 {/foreach} 55 </table>
五、编辑/languages/zh_cn/admin/goods.php，添加语言项
1 2 $_LANG['sales_volume_base'] = '销量基数';
六、编辑/includes/lib_goods.php，修改get_goods_info函数，计算累计销量（sales_volume_total）
1 /** 2 * 获得商品的详细信息 3 * 4 * @access public 5 * @param integer $goods_id 6 * @return void 7 */ 8 function get_goods_info($goods_id) 9 { 10 $time = gmtime(); 11 $sql = 'SELECT g.*, c.measure_unit, b.brand_id, b.brand_name AS goods_brand, m.type_money AS bonus_money, ' . 12 'IFNULL(AVG(r.comment_rank), 0) AS comment_rank, ' . 13 "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS rank_price " . 14 'FROM ' . $GLOBALS['ecs']->table('goods') .

七、以默认模板为例，编辑/themes/default/goods.dwt，添加显示累计销量
1 <li class="clearfix"> 2 <dd> 3 <strong>{$lang.sales_volume_total}<font color="#FE596A" size="2">{$goods.sales_volume_total}{$lang.pcs}</font></strong> 4 </dd> 5 <dd> 6 </dd> 7 </li>
八、编辑/languages/zh_cn/common.php，添加语言项
1 $_LANG['sales_volume_total'] = '累计销量：'; 2 $_LANG['pcs'] = '件';
