我正在创建一个用于登录和注销的表单。我的问题是当用户提交他们的用户名和密码然后显示带有该用户名的欢迎消息时。文件如下所示。
包含.php
<?php
session_start();
$host = "VKSolutions";
$username = "VKSolutions";
$password = "VKSolutions@1";
$db = "VKSolutions";
@mysql_connect($host,$username,$password) or die ("error");
@mysql_select_db($db) or die("error");
?>
登录.php
<?php
require_once('include.php');
$error = '';
$form = $_POST['submit'];
$user = $_POST['user'];
$password = $_POST['password'];
if( isset($form) ) {
if( isset($user) && isset($password) && $user !== '' && $password !== '' ) {
$sql = mysql_query("SELECT * FROM `accounts` WHERE user='$user' and
password='$password';");
if( mysql_num_rows($sql) != 0 ) { //success
$_SESSION['logged-in'] = true;
header('Location: members.php');
exit;
} else { $error = "Incorrect login info"; }
} else { $error = 'All information is not filled out correctly';}
}
?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Login</title>

<body>
<table width="80%" border="0"><form action="<?php $PHP_SELF; ?>" method="post" >
<tr>
<td><label>Employee Name:</label></td>
<td><input name="user" placeholder="Enter Name" type="text" value="<?php echo "$user";?>" /></td>

</tr>
<tr>
<td> </td>
<td><input valin="right" name="submit" type="submit" value="Log In" /></td>
</tr></form>
</table>
<?php
echo "<br /><span style=\"color:red\">$error</span>";
?>
</body>
</html>
成员.php
<?php
require_once('include.php');
if ( !isset($_SESSION['logged-in']) || $_SESSION['logged-in'] !== true) {
header('Location: login.php');
exit;
}
?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Staff Area</title>
</head>
<body>
<div style="margin-top:50px; color:#00F; margin-left:50px; font-size:18px; position:absolute">Welcome<?php echo "$user";?></div>
</body>
</html>
注销.php
<?php
session_start();
// if the user is logged in, unset the session
if (isset($_SESSION['logged-in'])) {
unset($_SESSION['logged-in']);
}
// now that the user is logged out,
// go to login page
header('Location: login.php');
?>
在我的 members.php 中，它登录但不显示用户名。我需要那个用户名。请找出问题所在。谢谢。
