回复讨论(解决方案)

那个不能放cookies的、用户下次登陆找收藏在购物车里的商品一旦没了咋办

ajax+数据库存储内容.

我也正需要购物车的资料呢,2楼所说的AJax+数据库是怎么实现的,有源码的话共享下...谢谢了!

<?php$act=$_GET[act];$product_id=$_GET[prcid];if($act=="add"){ 	$cars_id=explode(",",$_COOKIE[buypro]);	//echo "<pre class="brush:php;toolbar:false">";   	//print_r($cars_id);	//echo"
Copy after login
"; //exit; foreach($cars_id as $pr_id) { if($pr_id==$product_id) { echo "<script>alert('您已经购买了此商品,请查看购物车!');location.href='car.php';</script>"; exit; } } if(empty($_COOKIE[buypro])) { setcookie("buypro",$product_id,time()+3600); setcookie("buycount","1",time()+3600); } else { $newpro=$_COOKIE[buypro].",".$product_id; $newcount=$_COOKIE[buycount].","."1"; setcookie("buypro",$newpro,time()+3600); setcookie("buycount",$newcount,time()+3600); }}//删除if($act=="del"){$buy=$_COOKIE[buypro];$cars_id=explode(",",$buy);$buycountary=explode(",",$_COOKIE[buycount]);$newid=array();$carcount=array();for($i=0;$i

给你共享一个全套的,接点分,不够用了

也许不是非常强大,但是做个是个基本功能都OK。根据自己的要求自己可以在修改一下

thinkPHP购物车写法代码怎么写

学习中

未登录用户购物车商品存储到cookie,已登录用户存到数据库

<?php$method=@$_POST['method'];$good_id=@$_POST['id'];$good_name=@$_POST['name'];$good_item=@$_POST['item_code'];$good_num=@$_POST['number'];$good_car_array=unserialize($_COOKIE['good_car_string']);switch($method){	case "add":		if(array_key_exists($good_id,$good_car_array))		{			echo "购物车中已经存在该商品!";		}		else		{			$good_car_array[$good_id]=array($good_item,$good_name,$good_num);			echo "添加成功";		}	break;		case "change": 		$good_car_array[$good_id][2]=$good_num;	break;		case "del":		unset($good_car_array[$good_id]);	break;	 	case "delall": 		$good_car_array="";	break;}setcookie('good_car_string',serialize($good_car_array),time()+3600*30*24);print_r($good_car_array);?>
