php - "You must be logged in to access this page"错误

标签 php authentication

我设置了 login.php,以便每当登录成功时,它都会自动定向到 profile.php。但是,即使登录成功,每当我访问profile.php时,它仍然显示“您必须登录才能访问此页面”。为什么?

这是我的login.php:

$email = $_POST['email-field'];
$password = $_POST['password-field'];

if ($email && $password)
{
    $connect = mysql_connect("xx", "xx", "xx") or die("Couldnt connect!");
    mysql_select_db(xx) or die("Couldnt find db");

    $query = mysql_query("SELECT * FROM users WHERE email = '$email'");

    $numrows = mysql_num_rows($query);

    if ($numrows != 0)
    {

        while ($row = mysql_fetch_assoc($query))
        {
            $email = $row['email'];
            $md5password = $row['password'];
        }

        if ($email == $email && $md5password == md5($password))
        {
            header("Location: profile.php");
            $_SESSION['email']==$email;
        }
        else
            echo "Incorrect password";
    }
    else
        die("That user doessnt exist!");
}
else
    die("Please enter a username and a password");

还有我的profile.php:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<?php 

include('get-info.php');

session_start();

if ($_SESSION['email'])
    echo "<a href=logout.php>Logout</a>";
else
    die("You must be logged in to access this page");


?>

最佳答案

您忘记开始 session 。在每个想要使用 session 的页面上,您必须调用:

session_start();

还要确保在输出任何内容之前执行此操作,否则它将无法工作。
