ECSHOP取得当前分类下商品的品牌列表

比如我点击"分类一",显示"商品1","商品2","商品3","商品4"属于的品牌,即"品牌1","品牌2","品牌3" 如果点击"分类1.1",显示"商品1","商品2"属于的品牌,即"品牌1","品牌2" 如果点击"分类1.2",显示"商品3","商品4"属于的品牌,即"品牌1","品牌3" 具体解决方法 1.在include\lib_common.php中添加下面函数

/**
* 获得某个分类下的品牌列表
*
* @access  public
* @param   int     $cat
* @return  array
*/
function get_cat_brands($cat = 0, $app = 'category')
{
    $children = ($cat > 0) ? ' AND ' . get_children($cat) : '';
    $sql = "SELECT b.brand_id, b.brand_name, b.brand_logo, COUNT(g.goods_id) AS goods_num, IF(b.brand_logo > '', '1', '0') AS tag ".
            "FROM " . $GLOBALS['ecs']->table('brand') . "AS b, ".
                $GLOBALS['ecs']->table('goods') . " AS g ".
            "WHERE g.brand_id = b.brand_id $children " .
            "GROUP BY b.brand_id HAVING goods_num > 0 ORDER BY tag DESC, b.sort_order ASC";
    $row = $GLOBALS['db']->getAll($sql);
    foreach ($row AS $key => $val)
    {
        $row[$key]['url'] = build_uri($app, array('cid' => $cat, 'bid' => $val['brand_id']), $val['brand_name']);
    }

    return $row;
}

2.在category.php中查找$smarty->assign('current_cat_id', $cat_id); 在
