我正在做一个学校项目。

这里是项目的链接 http://www.dsu-class.com/zito82/lab10/

我需要使用 MVC 模型来编写 PHP 应用程序。除了一个步骤，我已经完成了所有步骤。我需要在客户列表中添加一个更新输入按钮。我从这个输入按钮启动到更新表单。当我提交此表单时，它应该会更新客户数据。

我有两个问题。我通过 foreach 循环创建了客户列表，并为每个更新按钮分配了一个 customerID，但是一旦我传递到表单，我就无法拉出 customerID 以通过该表单。

第二个问题是我的表单没有更新MYSQL数据库。

明确地说，我必须遵循这个 MVC 结构。构建 php 文件而不是函数对我来说会容易得多，但这就是我应该这样做的方式。

这是我的代码。我首先列出了 Controller ，其次是模型，最后是 View 。

require('../model/database.php');
require('../model/customer-db.php');

if (isset($_POST['action'])) {
    $action = $_POST['action'];
} else if (isset($_GET['action'])) {
    $action = $_GET['action'];
} khác {
    $action = 'display_customers';
}

if ($action == 'display_customers') {
    $customers = get_customers();
    include '../view/customer-list.php';
}
else if ($action == 'view_customerData') {
    $customerID = $_GET['customerID'];
    view_customerData($customerID);
    include '../view/customer-information.php';
}
else if ($action == 'update_customer') {
    $customerID = $_POST['customerID']; $firstName = $_POST['firstName']; $lastName = $_POST['lastName'];
    $address = $_POST['address']; $city = $_POST['city']; $state = $_POST['state']; $postalCode = $_POST['postalCode'];
    $countryCode = $_POST['countryCode']; $phone = $_POST['phone']; $email = $_POST['email'];

    update_customer($customerID, $firstName, $lastName, $address, $city, $state, $postalCode, $countryCode, $phone, $email);
    $customers = get_customers();
    include '../view/customer-list.php';
}
else if ($action == 'delete_customer') {
    $customerID = $_POST['customerID'];
    delete_customer($customerID);
    $customers = get_customers();
    include '../view/customer-list.php';
}
else if ($action == 'under-construction') {
    include('../under-construction.php');
} khác

?>

包含我对 Controller 的函数调用的模型

require_once('database.php');

function get_customers() {
    global $db;
    $query = "SELECT * FROM customers
              ORDER BY lastName";
    $customers = $db->query($query);
    return $customers;
}

function delete_customer($customerID) {
    global $db;
    $query = "DELETE FROM customers
              WHERE customerID = '$customerID'";
        $db->exec($query);
}

function view_customerData ($customerID) {
    global $db;
    $query = "SELECT * FROM customers
              WHERE customerID = '$customerID'";
    $customerData = $db->query($query);
    $customerData = $customerData->fetch();
    return $customerData;
}

function update_customer($customerID, $firstName, $lastName, $address, $city, $state, $postalCode, $countryCode, $phone, $email) {
    global $db;
    $query = "UPDATE customers
              SET
                  firstName = '$firstName', lastName = '$lastName', address = '$address', city = '$city', state = '$state',
                  postalCode = '$postalCode', countryCode = '$countryCode', phone = '$phone', email = '$email'
              WHERE customerID = '$customerID' ";
    $db->exec($query);

}

?>

我相信这会解决您的问题，但我假设您标记为 “Customer Update Form View” 的表单位于 customer-information.php.

在问题顶部的任何文件中，对于 view_customerData 操作...

else if ($action == 'view_customerData') {
    $customerID = $_GET['customerID'];
    $customer = view_customerData($customerID); // note the return value is now assigned
    include '../view/customer-information.php';
}

然后，在 customer-information.php 中，用数据预填表格。主要缺少的是客户 ID...

现在，我强烈建议您开始使用带有参数绑定(bind)的准备好的语句，而不是将值直接连接/插入到您的 SQL 查询中。
