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

转载作者：行者123 更新时间：2023-12-04 05:44:01

我有我的 login.php设置为每当登录成功时，它会自动定向到 profile.php .但是，即使登录成功，每次去profile.php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");


?>


<html>

    <head>

        <title>

            R-A | Profile

        </title>

        <link href='css.css' rel='stylesheet' type='text/css' />

    </head>

    <body class='body3' >

        <div class='logo-bar'>

            <div class='menu'>

                <img src='images/rateaway.png' class='logo-bar-img' />

                    <div class='menu-options'>

                        <a href='index.php' class='menu-links' >Home</a>

                        <a href='profile.php' class='menu-links' >Profile</a>

                        <a href='profile.php' class='menu-links' >Friends</a>

                    </div>

            </div>

        </div>

        <div class='profile-main-content' >

            <div class='profile-current-info'>

                <p class='profile-name'> <?php get_info('iran_mateu@yahoo.com', 'name'); ?> </p>

                <img src='<?php get_info('iran_mateu@yahoo.com', 'profilepic'); ?>' class='profile-pic'/>

                <p class='profile-dob' > Born: <?php get_info('iran_mateu@yahoo.com', 'dob'); ?> </p>

                <p class='profile-country' > Currently lives in: <?php get_info('iran_mateu@yahoo.com', 'country'); ?> </p>

                <p class='profile-gender' > Gender: <?php get_info('iran_mateu@yahoo.com', 'gender'); ?> </p>

            </div>

            <div class='profile-edit-info' >



            </div>

        </div>

    </body>

最佳答案

成功登录后，您不会写入 session 。考虑这部分:

if ($email==$email&&$md5password==md5($password))
    {
        header("Location: profile.php");
        $_SESSION['email']==$email;
    }

您应该使用 =而不是 == .既然你不是，你就是不是分配 $email至 $_SESSION['email'] .您没有分配任何内容，只是进行比较(并丢弃其返回值)。所以应该是:

$_SESSION['email'] = $email;

另外，您应该添加 session_start();到 login.php 的顶部，正如 minitech 在他的回答中所建议的那样。
