Question

我是这个领域的新手，这是我第一次参加会议，这个问题似乎很基本，但如果有人能帮助我，我会很感激。目前我已经使用会话进行了登录和注销页面，并希望显示已登录的特定用户的数据。用户登录后被重定向到retailer_login.php，除了登录表单，整个登录有4页和注销过程。

retailer_login.php，retailer_session.php，retailer_profile.php，retailer_logout.php

每个页面都运行正常，但我只能从数据库中显示用户的单个数据列，但我希望显示有关该特定用户的整个信息。

DATABASE

    Id  name  email          password  country  city   state  occupation
    1   sam   sam@gmail.com  sam       XYZ      ZBC    QWE    student

retailer_login页面

<?php
session_start(); // Starting Session

if (isset($_POST['submit'])) {
    try {
        if (empty($_POST['email']) || empty($_POST['password'])) {
            throw new Exception("email or Password is invalid");
        } else {
            // Define $email and $password
            $email      = $_POST['email'];
            $password   = $_POST['password'];
            // To protect MySQL injection for Security purpose
           $email      = stripslashes($email);
           $password   = stripslashes($password);
           $mail      = mysql_real_escape_string($email);
           $password   = mysql_real_escape_string($password);
         //Etablishing Connection with Server by passing server_name, user_id and password as a parameter
          $connection = mysql_connect("abc.com", "abc", "abc");
          // Selecting Database
            $db= mysql_select_db("abc", $connection);
            // SQL query to fetch information of registerd users and finds user match.
            $query = mysql_query("select * from retailerregister where password='$password' AND email='$email'", $connection);
            $rows = mysql_num_rows($query);

            if ($rows != 1)
                throw new Exception("email or Password is invalid");

            $_SESSION['login_user'] = $email; // Initializing Session
            header("location: retailer_profile.php"); // Redirecting To Other Page
            mysql_close($connection); // Closing Connection
        }
    }
    catch (Exception $e) {
        $_SESSION['login_error'] = $e->getMessage();
        header("Location: index.html");
    }
}
?>

retailer_session页面

$connection = mysql_connect("abc.com", "abc", "abc");
// Selecting Database
$db = mysql_select_db("abc", $connection);

$ses_sql=mysql_query("select * from retailerregister where email='$user_check'", $connection);

$row = mysql_fetch_assoc($ses_sql);
$login_session =$row['email'];

if(!isset($login_session)){
mysql_close($connection); // Closing Connection
header('Location: index.html'); // Redirecting To Home Page
}
?>

现在我只能使用$login_session才能在个人资料页面上显示电子邮件。任何人都可以通过会话告诉我如何在retailer_profile页面上显示登录用户的其他数据

Answer 1

只需创建有关当前登录用户的其他变量：

$row = mysql_fetch_assoc($ses_sql);
$login_session =$row['email'];

// another user data

$user_name = $row['name'];
$user_country = $row['country'];
$user_city = $row['city'];
$user_state = $row['state'];
$user_occupation = $row['occupation'];

或者你可以使用一个不应该被覆盖的变量：

$user_data = $row;

然后在剧本的某个地方：

echo $user_data['city']; // etc...

登录后使用会话检索单个用户数据
