ecshop开发需求:

1. 每个登录的用户在购物过程中的商品列表页、商品详细页、购物车都可以对商品进行批注;

2. 要求1中的批注会显示在订单中每个商品项中;

3. 用户每次登陆之后清除上次的批注。

修改方法:

【1】增加两个表:

-- ----------------------------

-- Table structure for `order_comment`

-- ----------------------------

DROP TABLE IF EXISTS `order_comment`;

CREATE TABLE `order_comment` (

`order_id` mediumint(8) NOT NULL,

`goods_id` mediumint(8) NOT NULL,

`goods_comment` varchar(500) DEFAULT NULL,

PRIMARY KEY (`order_id`,`goods_id`)

) ENGINE=InnoDB DEFAULT CHARSET=gbk;

-- ----------------------------

-- Table structure for `goods_comment`

-- ----------------------------

DROP TABLE IF EXISTS `goods_comment`;

CREATE TABLE `goods_comment` (

`goods_id` mediumint(8) NOT NULL,

`user_id` mediumint(8) NOT NULL,

`goods_comment` varchar(500) DEFAULT NULL,

PRIMARY KEY (`goods_id`,`user_id`)

obj.onblur = function(e)

{

var newComment = obj.value;

if (newComment != orgComment)

{

res = Ajax.call("./goods.php?is_ajax=1", "act=edit_goods_comment&val=" + encodeURIComponent(Utils.trim(newComment)).toJSONString() + "&id=" +goodsId, null, "POST", "JSON", false);
