你把内容用相应的源码高亮显示不是更方便别人为你解决问题吗?
------解决方案--------------------$act=$_GET[act];
$product_id=$_GET[prcid];
if($act=="add")
{
$cars_id=explode(",",$_COOKIE[buypro]);
//echo "

";
//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]))
