ecshop搜索商品货号搜索商品属性货号的实现方法

ECSHOP商城支持商品名称关键字,商品货号关键字等搜索商品，但不能按属性货号搜索。属性货号是ecshop属性库存的识别号，建立属性库存后，属性货号保存在products表中,代码号提供可按商品属 货号关键字搜索方法教程。
一、打开ECSHOP商城根目录找到search.php文件修改搜索关键字变量，添加属性货号关键字product_sn。

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

修改成：

$keywords  .= "(goods_name LIKE '%$val%' OR goods_sn LIKE '%$val%' OR product_sn LIKE '%$val%' OR keywords LIKE '%$val%' $sc_dsad)"; //ebingou.cn添加按属性货号product_sn查询

二、修改商品总数SQL语句，添加goods表与products表连接查询。

/* 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." )";

修改成：

/* 代码号ebingou.cn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('products') . " AS p ".
"ON g.goods_id = p.goods_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." )";

三、修改商品查询SQL语句，添加goods表与products表连接查询。

/* 查询商品 */
$sql = "SELECT g.goods_id, g.goods_name, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ".
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
"g.promote_price, g.promote_start_date, g.promote_end_date, g.goods_thumb, g.goods_img, g.goods_brief, g.goods_type ".
"FROM " .$ecs->table('goods'). " AS g ".
"LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
"ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' ".
"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." ) " .
"ORDER BY $sort $order";

修改成：

/* 代码号ebingou.cn查询商品 */
$sql = "SELECT g.goods_id, g.goods_name, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ".
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
"g.promote_price, g.promote_start_date, g.promote_end_date, g.goods_thumb, g.goods_img, g.goods_brief, g.goods_type ".
"FROM " .$ecs->table('goods'). " AS g ".
"LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
"ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' ".
"LEFT JOIN " . $GLOBALS['ecs']->table('products') . " AS p ".
"ON g.goods_id = p.goods_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." ) " .
"ORDER BY $sort $order";
