所以我试图在用户登录后显示用户名,但我无法让它工作......这是我正在使用的代码:
首先,用户必须登录。
<div>
<form method="POST" action="login.php">
<h2>LOGIN</h2>
<input type="text" placeholder="Username" name="username" />
<input type="password" placeholder="Password" name="password" />
<br />
<input class="btn btn-large btn-primary" type="submit" name="login" value="Log In" />
</form>
</div>
使用表单后,将加载此脚本,这是“login.php”:
<?php
session_start();
if(!$_SERVER['REQUEST_METHOD'] == 'POST') {
echo "Go away.<br /><br />";
exit();
}
if(mysql_connect('localhost', 'root', '')) {
if(mysql_select_db('users')) {
$username = $_POST['username'];
$password = $_POST['password'];
$query = "SELECT * FROM users WHERE username = '$username' AND password = '$password'";
$zoekresultaat = mysql_query($query);
if($zoekresultaat = mysql_affected_rows() > 0) {
$record = mysql_fetch_assoc($zoekresultaat);
$_SESSION['login'] = true;
$_SESSION['username'] = $record['username'];
header('location: dashboard.php');
} else {
header('location: loginerror.php');
}
exit();
} exit(); {
echo "Can't find database.";
}
} else {
echo "Can't connect to database.";
}
?>
完成后,用户将被重定向到“dashboard.php”,如下所示:
<?php include "includes/menu.php";?>
<div id='content'>
<h1><strong>Welkom <?php echo $_SESSION['username']; ?></strong></h1>
<p></p>
</div>
<?php include "includes/foot.php";?>
问题是当我尝试登录时出现以下错误:
注意:未定义变量:第 5 行 D:\xampp\htdocs\NGP\dashboard.php 中的 _SESSION
我真的很迷茫,希望能在这里得到一些答案!提前致谢!
