有时我们需要在网站首页添加某个分类下的品牌，这就需要做些ecshop的二次开发，我写了一个简单的函数只要放在index.php中直接调用就ok了。

function get_cat_brands( $cat, $num = 0, $app = “category” )
{
$where = “”;
if ( $num != 0 )
{
$where = ” limit “.$num;
}
$children = 0 < $cat ? ” 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 “.$where;
$row = $GLOBALS['db']->getAll( $sql );
foreach ( $row as $key => $val )
{
$row[$key]['id'] = $val['brand_id'];
$row[$key]['name'] = $val['brand_name'];
$row[$key]['logo'] = $val['brand_logo'];
$row[$key]['url'] = build_uri( $app, array(
“cid” => $cat,
“bid” => $val['brand_id']
), $val['brand_name'] );
}
return $row;
}

其中$cat就是分类ID。
