Question

我获得了一堆代码（PHP），但没有很好地记录;那说，我有一些对我没有任何意义的形式逻辑。这是页面html代码：

<?php 
session_start();

ini_set('display_errors', 1);
error_reporting(E_ALL);

$itemcount = isset($_SESSION['itemcount']) ? $_SESSION['itemcount'] : 0;
if ($itemcount == 0)
    {
        header("Location: "."error.php?msg=".rawurlencode("Please add items to your shopping cart before checking out."));
        exit;
    } 

if (!isset($_SESSION['email']))
    {
        header("Location: "."error.php?msg=".rawurlencode("We did not find your information, please fill the needed information again."));
        exit;
    } 

if ($_SERVER['REQUEST_METHOD'] == 'POST')
    {
        $_SESSION['shipname'] = $_POST['shipname'];
        $_SESSION['shipaddress'] = $_POST['shipaddress'];
        $_SESSION['shipzip'] = $_POST['shipzip'];
        $_SESSION['shipcity'] = $_POST['shipcity'];
        $_SESSION['shipstate'] = $_POST['shipstate'];
        $_SESSION['shipcountry'] = $_POST['shipcountry'];

        $_SESSION['paymenttype'] = $_POST['paymenttype'];
        $_SESSION['cardname'] = $_POST['cardname'];
        $_SESSION['cardno'] = $_POST['cardno'];
        $_SESSION['cardmonth'] = $_POST['cardmonth'];
        $_SESSION['cardyear'] = $_POST['cardyear'];

        header("Location: "."thankyou.php");
    } 

$shipname = isset($_SESSION['shipname']) ? $_SESSION['shipname'] : '';
$shipaddress = isset($_SESSION['shipaddress']) ?    $_SESSION['shipaddress'] : '';
$shipzip = isset($_SESSION['shipzip']) ? $_SESSION['shipzip'] : '';
$shipcity = isset($_SESSION['shipcity']) ? $_SESSION['shipcity'] : '';
$shipstate = isset($_SESSION['shipstate']) ? $_SESSION['shipstate'] : '';
$shipcountry = isset($_SESSION['shipcountry']) ? $_SESSION['shipcountry'] : '';
$cardname = isset($_SESSION['cardname']) ? $_SESSION['cardname'] : '';
$cardno = isset($_SESSION['cardno']) ? $_SESSION['cardno'] : '';

?>

这是表单html：

<div id="wb_checkout" style="position:absolute;width:957px; height:374px;">
  <form name="checkout" method="post" action="checkout.php" id="checkout">
    <div id="wb_Text3" style="position:absolute;left:32px;top:88px;width:88px;height:34px;z-index:36;">

    <input type="submit" id="Button1" name="submitOrder" value="Submit Order" style="position:absolute;left:612px;top:317px;width:110px;height:36px;z-index:46;">
    <input type="submit" id="Button2" name="cancelOrder" value="Cancel Order" style="position:absolute;left:761px;top:318px;width:114px;height:35px;z-index:47;">
  </form>
</div>

这是表格的图像：

问题是该页面没有呈现;它只是跳到下一页（thankyou.php）而没有显示表单，因此用户可以输入发货信息。此外，根据作者使用的逻辑，我看不到送货信息将如何进入下一页，因为它之前有一个标题声明。最后，我没有看到处理提交订单或取消订单的任何逻辑。

我是PHP的菜鸟，但学习速度快;我已经编程很长很长时间了，这没有任何意义。有人可以告诉我：

为什么页面没有显示
是我怀疑的那种逻辑吗？如果有的话，最好的解决方法是什么？
两个按钮应该如何工作？（这些是“提交订单”按钮的设置）

Answer 1

更好的方法是使用它：

if(isset($_POST['submitOrder']))

而不是：

if($_SERVER['REQUEST_METHOD'] == 'POST')

＆＃34;提交订单＆＃34;按钮只有在点击的按钮才会被设置。
