一两句说不清楚………

用html css做出商品样子和购物车样子，

然后用javascript来对买这个动作做处理，把商品的信息存起来，通过js把商品信息传递给购物车，让购物车能够显示；
另一方面把信息交给php，写入数据库。

我这么说你明白了么……追问

谢谢你的回答，思路是明白了，具体的话html css都好说，js大概也还可以，php是不太明白怎么做，能不能写一段代码给我看一下，就是用html css js php写的购物车

追答

你如果不用写进去数据库可以不用php,用php的话，其实就是商品信息放在表单里，提交给一个php文件，在php文件中接收商品的信息，然后连接数据库，保存就好了

我给你发个大概的例子；

//表单
<html>
<head>
</head>
<body>
<form action="regist.php" method="get">
user:<input type="text" name="userName">
password:<input type="password" name="password"><br/>
<input type="submit" value="注册" name="res">
</form>
</body>
</html>
你能不能再追问一下写不下

追问

可以私信跟你聊么？大概是不用提交到数据库的。

追答

可以
