注销会议上，我想创建登录和注销会话创建登录和PHP和数据库
我在MySQL数据库表看上去就像命名为loginproc.php这
CREATE TABLE members (
id int(10) NOT NULL auto_increment,
username varchar(20) NOT NULL,
password varchar(20) NOT NULL, PRIMARY KEY (id))
ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=3 ;
和MySQL连接
<?php
// Inialize session
session_start();
// Include database connection settings
$hostname = 'localhost'; // Your MySQL hostname. Usualy named as 'localhost', so you're NOT necessary to change this even this script has already online on the internet.
$dbname = 'database'; // Your database name.
$username = 'root'; // Your database username.
$password = ''; // Your database password. If your database has no password, leave it empty.
// Let's connect to host
mysql_connect($hostname, $username, $password) or DIE('Connection to host is failed, perhaps the service is down!');
/Select the database
mysql_select_db($dbname) or DIE('Database name is not available!');
// Retrieve username and password from database according to user's input
$login = mysql_query("SELECT count(*) FROM members WHERE (username = '" . mysql_real_escape_string($_POST['user']) . "') and (password = '" . mysql_real_escape_string(md5($_POST['pass'])) . "')");
$result=mysql_fetch_array($login);
// Check username and password match
if (mysql_num_rows($result) == 1) {
// Set username session variable
$_SESSION['username'] = $_POST['user'];
// Jump to secured page
header('Location: securedpage.php');
}
else {
// Jump to login page
header('Location:career.php');
}
?>
然后securedpage.php
创建<?php
// Inialize session
session_start();
// Check, if username session is NOT set then this page will jump to login page
if (!isset($_SESSION['user'])) {
header('Location: career.php');
}
?>
<html>
<head>
<title>Secured Page</title>
</head>
<body>
<p>This is secured page with session: <b><?php echo $_SESSION['username']; ?></b>
<br>You can put your restricted information here.</p>
<p><a href="logout.php">Logout</a></p>
</body>
</html>
的index.php
<html>
<head>
</head>
<body>
<form action="loginproc.php" method="post">
UserName:<input type="text" name="user" >
<p> </p>
Password:<input type="password" name="pass" >
<p> </p>
<input type="submit" value=" Login Here " >
<span class="style30">| New?</span>
<a href="signup.php"><span class="style32">Start Here</span>
</form></body></html>
，最后注销命名为logout.php页面
<?php
// Inialize session
session_start();
// Delete certain session
unset($_SESSION['username']);
// Delete all session variables
// session_destroy();
// Jump to login page
header('Location: index.php');
?>
现在我的问题是，当我输入用户名和密码，它会留只有在index.php，它不会进入另一个页面。请看看这段代码，并告诉我什么时候我做错了。
谢谢。
的'index.php'代码看起来好像没什么问题。在index.php中还有没有其他的代码在这里粘贴？另外这行'loginproc.php'中的'/选择数据库'没有被正确评论，并且会被解释为一个语句。 –
如果这是你的实际代码，该行'/选择database'缺少一个'/'所以尝试将其更改为'//选择database' - 这种类型的PHP评论需要2个''//它 –
不'$ _SESSION [“用户”]'是'$ _SESSION [“用户名”]' –
