javascript - 如何纠正服务器中的 php 重定向错误

Question

我的 php 购物车服务器重定向错误到目前为止我所做的是在 jquery 中我必须将商品 id 和单价发送到 shop-cart.php

我的js代码是

var id = getUrlParameter('id');
var unitprice=$(".couponPrice").text(); 
window.location = 'shop-cart.php?id=' + id +'&unitprice='+ unitprice;

当我点击“添加到购物车”按钮时，它会重定向到

www.domainname/shop-cart.php?id=sp_gt1&unitprice=1

在商店购物车中，我必须生成一个订单 ID，我的 shop-cart.php 代码是

<?php
ob_start();
session_start();
//error reporting
include "script/db.php";
error_reporting(E_ALL);
ini_set('display_errors','1');
error_reporting(E_ERROR | E_PARSE);
?>


<?php
////////order id generate/////////
date_default_timezone_set('Asia/Kolkata');
        $stamp = date("ymdhis");

$orderid = $stamp;


if(isset($_GET['OrderId']))
{
    $_SESSION['OrderId']=$_GET['OrderId'];
}


/////////////////////////////////////////////////////////////////////////////
// SECTION-1     (if you want to add items to your shopping cart)
/////////////////////////////////////////////////////////////////////////////
if (isset($_GET['id'])) 
{

    $pid = $_GET['id'];
    $quantity=1;
    $unitprice=$_GET['unitprice'];

    $wasFound = false;
    $i = 0;

    // If the cart session variable is not set or cart array is empty
    if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1)                  { 

        // RUN IF THE CART IS EMPTY OR NOT SET
        $_SESSION["cart_array"] = array(0 => array("item_id" => $pid, "quantity" => $quantity,"unit_price"=>$unitprice));
    } 
    else 
    {
        // RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
        foreach ($_SESSION["cart_array"] as $each_item) { 
              $i++;
              while (list($key, $value) = each($each_item)) {
                  if ($key == "item_id" && $value == $pid) {
                      // That item is in cart already so let's adjust its quantity using array_splice()
                      array_splice($_SESSION["cart_array"], $i-1, 1, array(array("item_id" => $pid, "quantity" => $each_item['quantity'] + 1,"unit_price"=>$unitprice)));
                      $wasFound = true;
                  } // close if condition
              } // close while loop
           } // close foreach loop
           if ($wasFound == false) 
           {
               array_push($_SESSION["cart_array"], array("item_id" => $pid, "quantity" => $quantity,"unit_price"=>$unitprice));
           }

    }//else
    header("location:shop-cart.php?OrderId=".$orderid);
            exit();

}//if
?>

我的问题是当我单击本地主机中的“添加到购物车”按钮时，它会显示

http://localhost/mydomainname/shop-cart.php?OrderId=151011020441

但在在线服务器中它显示

http://domainname/shop-cart.php?id=sp_gt1&unitprice=1 

body 的其余部分显示空白。我希望它重定向到显示 orderId，如本地主机中所示，任何帮助将不胜感激。

        $("#add-to-cart").click(function(e) {
    e.preventDefault();
    error();

}); 
function error(){
      function getUrlParameter(sParam)
{
    var sPageURL = window.location.search.substring(1);
    var sURLVariables = sPageURL.split('&');
    for (var i = 0; i < sURLVariables.length; i++) 
    {
        var sParameterName = sURLVariables[i].split('=');
        if (sParameterName[0] == sParam) 
        {
            return sParameterName[1];

        }
    }
}  
var id = getUrlParameter('id');
var unitprice=$(".couponPrice").text(); 


        window.location = 'shop-cart.php?id=' + id +'&unitprice='+ unitprice;




    };//add-to-cart////
