登录后如何在会员页面显示全名？

Question

谁是代码，需要放在哪里，以显示会话用户名为登录用户的会话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>

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

用户输入用户名和密码后，需要从数据库中选择用户，并将名和姓放入会话

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，您需要将其放入会话。

<?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.';
}

在重定向后，请始终使用exit。

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