Question

<?php
session_start();
include_once 'db.login.php';

if (isset($_SESSION['users']) != "") {
    header("Location: profile.php");
}

if (isset($_POST['btn-login'])) {
    $username = mysqli_real_escape_string($con, $_POST['username']);
    $upass = mysqli_real_escape_string($con, $_POST['password']);
    $res = mysqli_query($con, "SELECT * FROM users WHERE username='$username'");
    $row = mysqli_fetch_array($res);

    if ($row['password'] == md5($upass)) {
        $_SESSION['users'] = $row['id'];
        header("Location: profile.php");
    } else {
        $err = "<p style='color: red'>Wrong Username or Password</p>";
        ?>
        <?php
    }
}
?>

我正在尝试的方法，但似乎没有显示任何内容

<?= $_SESSION['username'] ?>">

我基本上是在回应登录会话的用户名

Answer 1

你在

中填写会话

$_SESSION['users']

但是回声

$_SESSION['username']

Answer 2

<?php
session_start();
include_once 'db.login.php';

if(isset($_SESSION['users']) && $_SESSION['users'] != "")
{
    header("Location: profile.php");
    exit();

}

if(isset($_POST['btn-login']))
{
    $username = mysqli_real_escape_string($con, $_POST['username']);
    $upass = mysqli_real_escape_string($con, $_POST['password']);
    $res=mysqli_query($con, "SELECT * FROM users WHERE username='$username'");
    $row=mysqli_fetch_array($res);

    if($row['password'] == md5($upass))
    {
        $_SESSION['users'] = $row['id'];
        $_SESSION['username'] = $row['username'];


        header("Location: profile.php");
    }
    else
    {
            $err = "<p style='color: red'>Wrong Username or Password</p>";
        ?>

        <?php
    }
}
?>

您没有在任何地方定义$_SESSION['username']。
