请在我的代码中找出错误，它不会重定向到cart-page.php是否重定向到 http://allsolution.co/product-page.php?productid=1&command=add。它在localhost上工作正常，它也不会在服务器上显示ant错误 在此处输入代码 产品page.php文件
<?php
include("include/db.php");
include("include/functions.php");
if(isset($_REQUEST['command']) && $_REQUEST['command']=='add' && $_REQUEST['productid']>0){
$pid=$_REQUEST['productid'];
addtocart($pid,1);
header("location:cart-page.php");
exit();
}
?>
