Question

我创建了一个登录页面和一个主页面，我喜欢在登录后回显我的用户名。我不确定要修复什么，或者添加什么。

以下是我的代码：

的login.php

<?php
session_start();
require_once './config/config.php';
//If User has already logged in, redirect to dashboard page.
if (isset($_SESSION['user_logged_in']) && $_SESSION['user_logged_in'] === TRUE) {
     $_SESSION['first_name'] = $_POST['first_name'];
    header('Location:index.php');
}

//If user has previously selected "remember me option", his credentials are stored in cookies.
if(isset($_COOKIE['username']) && isset($_COOKIE['password']))
{
	//Get user credentials from cookies.
	$username = filter_var($_COOKIE['username']);
	$passwd = filter_var($_COOKIE['password']);
	$db->where ("user_name", $username);
	$db->where ("passwd", $passwd);
    $row = $db->get('admin_accounts');

    if ($db->count >= 1) 
    {
    	//Allow user to login.
        $_SESSION['user_logged_in'] = TRUE;
        $_SESSION['admin_type'] = $row[0]['admin_type'];
        header('Location:index.php');
        exit;
    }
    else //Username Or password might be changed. Unset cookie
    {
        unset($_COOKIE['username']);
        unset($_COOKIE['password']);
        setcookie('username', null, -1, '/');
        setcookie('password', null, -1, '/');
        header('Location:login.php');
        exit;
    }
}
?>
<!DOCTYPE html>
<html lang="en-EN">
        <h1>Login</h1>

<div class="work n5">

 <div id="login">

		<p style="font-size:130%;"><strong>Welcome.</strong> Please login.</p>

		<form method="POST" action="authenticate.php">

			<fieldset style="border:none;">

				<p><input type="text" name="username" required="required" required value="Username" onBlur="if(this.value=='')this.value='Username'" onFocus="if(this.value=='Username')this.value='' "></p> 

				<p><input type="password" name="passwd" required="required" required value="Password" onBlur="if(this.value=='')this.value='Password'" onFocus="if(this.value=='Password')this.value='' "></p> 

				<p><a onclick="toggleModal()">Forgot Password?</a></p>
                	<?php
				if(isset($_SESSION['login_failure'])){ ?>
				<div class="alert alert-danger alert-dismissable fade in">
					<a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
					<?php echo $_SESSION['login_failure']; unset($_SESSION['login_failure']);?>
				</div>
				<?php } ?>
				<p><input type="submit" style="font:inherit; font-size:13px;" value="Login"></p>

			</fieldset>

		</form>
    </div>
</div>

Index.php（登录后的页面）

<?php
session_start();
require_once './config/config.php';
require_once 'includes/auth_validate.php';

//Get DB instance. function is defined in config.php
$db = getDbInstance();

//Get Dashboard information
$numCustomers = $db->getValue ("customers", "count(*)");

?>
<!DOCTYPE html>
    <html lang="en-EN">
    
                    <div class="infoWrapper">
                        <div class="title">
                            <span>Welcome Back</span>
                        </div>
                        
                        <div class="counter">
                            <span> <?php echo $_SESSION['user_name'];?>  - Tech</span>
                        </div>

authenticate.php

<?php 
require_once './config/config.php';
session_start();
if ($_SERVER['REQUEST_METHOD'] === 'POST') 
{
    $username = filter_input(INPUT_POST, 'username');
    $passwd = filter_input(INPUT_POST, 'passwd');
    $remember = filter_input(INPUT_POST, 'remember');
    $passwd=  md5($passwd);
   	
    //Get DB instance. function is defined in config.php
    $db = getDbInstance();

    $db->where ("user_name", $username);
    $db->where ("passwd", $passwd);
    $row = $db->get('admin_accounts');
     
    if ($db->count >= 1) {
        $_SESSION['user_logged_in'] = TRUE;
        $_SESSION['admin_type'] = $row[0]['admin_type'];
       	if($remember)
       	{
       		setcookie('username',$username , time() + (86400 * 90), "/");
       		setcookie('password',$passwd , time() + (86400 * 90), "/");
       	}
        header('Location:index.php');
        exit;
    } else {
        $_SESSION['login_failure'] = "Invalid username or password";
        header('Location:login.php');
        exit;
    }
  
}
