网店ECSHOP头部搜索添加品牌、分类名搜索条件

添加搜索条件，按品牌搜索，按分类名搜索，方法如下：
打开search.php
搜索下面代码：

$keywords  .= "(goods_name LIKE '%$val%' OR goods_sn LIKE '%$val%' OR keywords LIKE '%$val%' $sc_dsad)";

将上面代码替换为：

$keywords  .= "(goods_name LIKE '%$val%' OR cat_name LIKE '%$val%' OR brand_name LIKE '%$val%' OR goods_sn LIKE '%$val%' OR g.keywords LIKE '%$val%' $sc_dsad)";

搜索下面代码：
：
/* 获得符合条件的商品总数 */  
$sql   = "SELECT COUNT(*) FROM " .$ecs->table('goods'). " AS g ".  
    "WHERE g.is_delete = 0 AND g.is_on_sale = 1 AND g.is_alone_sale = 1 $attr_in ".  
    "AND (( 1 " . $categories . $keywords . $brand . $min_price . $max_price . $intro . $outstock ." ) ".$tag_where." )";  
$count = $db->getOne($sql);  
* 获得符合条件的商品总数 */  
$sql   = "SELECT COUNT(*) FROM " .$ecs->table('goods'). " AS g ".  
    "WHERE g.is_delete = 0 AND g.is_on_sale = 1 AND g.is_alone_sale = 1 $attr_in ".  
    "AND (( 1 " . $categories . $keywords . $brand . $min_price . $max_price . $intro . $outstock ." ) ".$tag_where." )";  
$count = $db->getOne($sql); 

将上面代码替换为：

/* 获得符合条件的商品总数 */  
$sql   = "SELECT COUNT(*) FROM " .$ecs->table('goods'). " AS g ".  
        "LEFT JOIN " . $GLOBALS['ecs']->table('brand') . " AS b ON b.brand_id =g.brand_id ".

        "LEFT JOIN " . $GLOBALS['ecs']->table('category') . " AS c ON c.cat_id = g.cat_id  ".

    "WHERE g.is_delete = 0 AND g.is_on_sale = 1 AND g.is_alone_sale = 1 $attr_in ".  
    "AND (( 1 " . $categories . $keywords . $brand . $min_price . $max_price . $intro . $outstock ." ) ".$tag_where." )";  
$count = $db->getOne($sql); 

搜索下面代码：

        "ORDER BY $sort $order";  
$res = $db->SelectLimit($sql, $size, ($page - 1) * $size);

将上面代码替换为：
