Question

我希望这种解释有意义......

我有一个使用SESSION / PHP / MySQLi工作的购物车，我的理由是我无法通过Checkout屏幕根据登录的客户ID显示ShipTo地址。

数据库表是“客户”，字段名称是“id”

工作：
客户可以注册/登录
页面受非成员保护所有购物车详细信息都会通过结帐

不工作：（checkout.php）
根据ID显示当前客户ShipTo - 当前设置为默认ID“5”，以便我可以测试它。

的login.php 这将在登录前检查email / psw是否存在并使用相同的“sesscustomerID”引用。

<?php
    session_start();
    include("db.php"); //Establishing connection with database

    $error = ""; //Variable for storing our errors.
    if(isset($_POST["submit"]))
    {
        if(empty($_POST["email"]) || empty($_POST["password"]))
        {
            $error = "Both fields are required.";
        }else
        {
            // Define $email and $password
            $email=$_POST['email'];
            $password=$_POST['password'];

            // To protect from MySQL injection
            $email = stripslashes($email);
            $password = stripslashes($password);
            $email = mysqli_real_escape_string($db, $email);
            $password = mysqli_real_escape_string($db, $password);
            $password = md5($password);

            //Check email and password from database
            $sql="SELECT id FROM customers WHERE email='$email' and password='$password'";
            $result=mysqli_query($db,$sql);
            $row=mysqli_fetch_array($result,MYSQLI_ASSOC);

            //If email and password exist in our database then create a session.
            //Otherwise echo error.

            if(mysqli_num_rows($result) == 1)
            {
                $_SESSION['sessCustomerID'] = $email; // Initializing Session
                header("location: products.php"); // Redirecting To Other Page
            }else
            {
                $error = "Incorrect email or password.";
            }

        }
    }

?>

checkout.php

<?php
include 'check.php';    
?>

<?php
// include database configuration file
include 'dbConfig.php';

// initializ shopping cart class
include 'Cart.php';
$cart = new Cart;

// redirect to home if cart is empty
if($cart->total_items() <= 0){
    header("Location: products.php");
}

// set customer ID in session
$_SESSION['sessCustomerID'] = 5;

// get customer details by session customer ID
$query = $db->query("SELECT * FROM customers WHERE id = ".$_SESSION['sessCustomerID']);
$custRow = $query->fetch_assoc();
?>
