为ecshop用户提供商品批备注功能_ecshop教程_php教程

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：

-- ----------------------------
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`)
) ENGINE=MyISAM DEFAULT CHARSET=gbk;

function addGoodsComment(obj, goodsId)
{
/* 保存原始的内容 */
var orgComment = obj.value;

/* 编辑区失去焦点的处理函数 */

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);
