分类页的品牌筛选以LOGO形式显示

1、修改 category.dwt 文件

将<span>{$brand.brand_name}</span>
修改为
<span>{if $brand.brand_logo}<img src="/data/brandlogo/{$brand.brand_logo}" width="40px" height="40px">{else}{$brand.brand_name}{/if}</span>

将<a href="{$brand.url}">{$brand.brand_name}</a> 

修改为
<div color: rgb(92, 92, 92);font-family: 'Microsoft Yahei', Tahoma, Arial, Helvetica, sans_serif;font-size: 14px;line-height: 35px;text-indent: 28px;background-color: rgb(255, 255, 255)">
*display:inline;
"><a href="{$brand.url}" color: rgb(92, 92, 92);font-family: 'Microsoft Yahei', Tahoma, Arial, Helvetica, sans_serif;font-size: 14px;line-height: 35px;text-indent: 28px;background-color: rgb(255, 255, 255)">
2、修改 category.php 文件
将$sql = "SELECT b.brand_id, b.brand_name, COUNT(*) AS goods_num ".
修改为
$sql = "SELECT b.brand_id,b.brand_logo, b.brand_name, COUNT(*) AS goods_num ".

在$brands[$temp_key]['brand_name'] = $val['brand_name'];
下面增加
$brands[$temp_key]['brand_logo'] = $val['brand_logo'];

在$brands[0]['brand_name'] = $_LANG['all_attribute'];
下面增加
$brands[0]['brand_logo']='';

3.添加CSS样式
div.akl:hover{filter:alpha(opacity=50);
-moz-opacity: 0.5;
opacity: 0.5;
}
