Question

我有两个不同的文件。

Checkoutstep4.php

Checkoutstep5.php

提交第一个表单时，我想获取已提交的'country'的值，并在IF函数中使用它：

这是我到目前为止使用的会话变量... 但我得到一个错误说未定义的索引，我不知道为什么。

checkoutDeliveryInfo（提交投放详细信息表单时运行的文件）。

<?php
session_start();
require_once 'DatabaseConnection.php';

$_SESSION['customerid'];

if (isset($_POST['submit'])) {


    $stmt = $pdo->prepare("INSERT INTO DeliveryDetails (customerid,firstname,lastname, addressline1, addressline2, city, county, country, postalcode)
            VALUES ({$_SESSION['customerid']}, :firstname, :lastname, :addressline1, :addressline2, :city, :county, :country, :postalcode)");

    $stmt->bindParam(':firstname', $firstname);
    $stmt->bindParam(':lastname', $lastname);
    $stmt->bindParam(':addressline1', $addressline1);
    $stmt->bindParam(':addressline2', $addressline2);
    $stmt->bindParam(':city', $city);
    $stmt->bindParam(':county', $county);
    $stmt->bindParam(':country', $country);
    $stmt->bindParam(':postalcode', $postalcode);


    $firstname = $_POST['firstname'];
    $lastname = $_POST['lastname'];
    $addressline1 = $_POST['addressline1'];
    $addressline2 = $_POST['addressline2'];
    $city = $_POST['city'];
    $county = $_POST['county'];
    $country = $_POST['country'];
    $postalcode = $_POST['postalcode'];



    $stmt->execute();

    $_SESSION['country'] = $country;

    header('location:../View/php_shopping_cart/CheckoutStep5.php');
}

正在使用会话变量的Checkoutstep5.php文件中的IF函数：

    <?php
    include '../../Model/ShoppingCart.php';
    $shoppingCart = new ShoppingCart;
    // redirect to home if cart is empty
    if ($shoppingCart->total_items() <= 0) {
        header("Location: ../index.php");
    }

    ?>
          <div class="shippingcost"><strong>Shipping Cost <?php
                                if ($_SESSION['country'] != 'GIB') {
                                    $shippingcost = '10.00';
                                } else {
                                    $shippingcost = 'FREE';
                                }
                                echo $shippingcost;
                                ?></strong>
</div>

感谢任何帮助。

更新：错误消息：

注意：未定义的索引：246行/home/k1509759/www/barbarycoast/View/php_shopping_cart/CheckoutStep5.php中的国家/地区

我设法通过从会话中提取所有变量然后使用我想要的个人来完成它。

extract($_SESSION);

if ($country == 'GIB') {
    $shippingcost = 'FREE';
} else if ($country == 'GBR') {
    $shippingcost = '£10.00';
} else if ($country == 'ESP') {
    $shippingcost = '£10.00';
}

表单提交到If函数时传递给另一个文件的值
