ecshop按属性货号搜索

ECSHOP前台可按商品名称关键字、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属性库存的唯一识别号，建立属性库存后，属性货号保存在products表中，下面介绍如何开发按属性货号关键字搜索。

编辑/search.php

一、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)";

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

修改为

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

//添加按属性货号product_sn查询

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

//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." )";

/* 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('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." )";

/* 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";

/* 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";

修改为

/search.php

PHP

/* 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 ".

"AND (( 1 " . $categories . $keywords . $brand . $min_price . $max_price . $intro . $outstock . " ) ".$tag_where." ) " . "ORDER BY $sort $order";

/* 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, ".

"ORDER BY $sort $order";
