如何在登录后在成员页面上显示全名

Question

谁是代码，需要放在哪里，以显示具有会话用户名的登录用户的会话fname和lname。

这是我的登录页面：

    <?php session_start();
//include config
require_once('includes/config.php');
//check if already logged in move to home page
if( $user->is_logged_in() ){ header('Location: index.php'); } 
//process login form if submitted
if(isset($_POST['submit'])){
$username = $_POST['username'];
$password = $_POST['password'];

if($user->login($username,$password)){ 
    $_SESSION['username'] = $username;
    header('Location: memberpage.php');
    exit;
} else {
    $error[] = 'Погрешно корисничко име или лозинка, или вашиот акаунт не е активиран.';
}

这是我的会员页面：

<?php session_start(); 
require('includes/config.php'); 
//if not logged in redirect to login page
if(!$user->is_logged_in()){ header('Location: login.php'); } 
//define page title
$title = 'Профил';
//include header template
require('layout/header.php'); 
?>
<div class="container">
<div class="row">
    <div class="col-xs-12 col-sm-8 col-md-6 col-sm-offset-2 col-md-offset-3">
             <h2>Добредојдовте: <?php print_r($_SESSION)
;?></h2>
            <p><a href='logout.php'>Logout</a></p>
            <p><a href='Update.php'>Update</a></p>
            <hr>
    </div>
 </div>

</div>

使用此代码时"print_r（$_SESSION）"仅打印用户名和成员id。我厌倦了使用"$_SESSION['Fname']=$_POST['Fname]；"

用户输入username和password后，需要从数据库中选择用户，并将名字和姓氏放入session

在您的情况下，您应该编辑login方法。它应该返回当前用户的行。之后，您需要将其放入session。

<?php session_start();
//include config
require_once('includes/config.php');
//check if already logged in move to home page
if( $user->is_logged_in() ){ header('Location: index.php'); } 
//process login form if submitted
if(isset($_POST['submit'])){
$username = $_POST['username'];
$password = $_POST['password'];

if($row = $user->login($username,$password)){ 
    $_SESSION['username'] = $username;
    $_SESSION['firstname'] = $row['firstname'];
    $_SESSION['lastname'] = $row['lastname'];
    header('Location: memberpage.php');
    exit;
} else {
    $error[] = 'Погрешно корисничко име или лозинка, или вашиот акаунт не е активиран.';
}

重定向后也始终使用exit。

if(!$user->is_logged_in()){ header('Location: login.php');exit; }
