註銷會議上，我想創建登錄和註銷會話創建登錄和PHP和數據庫
我在MySQL數據庫表看上去就像命名爲loginproc.php這
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連接
<?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'] = $_POST['user'];
// Jump to secured page
header('Location: securedpage.php');
}
else {
// Jump to login page
header('Location:career.php');
}
?>
然後securedpage.php
創建<?php
// Inialize session
session_start();
// Check, if username session is NOT set then this page will jump to login page
if (!isset($_SESSION['user'])) {
header('Location: career.php');
}
?>
<html>
<head>
<title>Secured Page</title>
</head>
<body>
<p>This is secured page with session: <b><?php echo $_SESSION['username']; ?></b>
<br>You can put your restricted information here.</p>
<p><a href="logout.php">Logout</a></p>
</body>
</html>
的index.php
<html>
<head>
</head>
<body>
<form action="loginproc.php" method="post">
UserName:<input type="text" name="user" >
<p> </p>
Password:<input type="password" name="pass" >
<p> </p>
<input type="submit" value=" Login Here " >
<span class="style30">| New?</span>
<a href="signup.php"><span class="style32">Start Here</span>
</form></body></html>
，最後註銷命名爲logout.php頁面
<?php
// Inialize session
session_start();
// Delete certain session
unset($_SESSION['username']);
// Delete all session variables
// session_destroy();
// Jump to login page
header('Location: index.php');
?>
現在我的問題是，當我輸入用戶名和密碼，它會留只有在index.php，它不會進入另一個頁面。請看看這段代碼，並告訴我什麼時候我做錯了。
謝謝。
的'index.php'代碼看起來好像沒什麼問題。在index.php中還有沒有其他的代碼在這裏粘貼？另外這行'loginproc.php'中的'/選擇數據庫'沒有被正確評論，並且會被解釋爲一個語句。 –
如果這是你的實際代碼，該行'/選擇database'缺少一個'/'所以嘗試將其更改爲'//選擇database' - 這種類型的PHP評論需要2個''//它 –
不'$ _SESSION [「用戶」]'是'$ _SESSION [「用戶名」]' –
