早上好。
构建一个用于管理汽车的网络应用,如您所见in this image。
在上图中看到的是文件index.php,该文件配置为显示用户是否登录的不同内容:
<body>
<div class="container">
<h2>Welcome to the Automobiles Database</h2>
<?php
if ( isset($_SESSION['error']) ) {
echo('<p style="color: red;">'.htmlentities($_SESSION['error'])."</p>\n");
unset($_SESSION['error']);
}
if ( isset($_SESSION['success']) ) {
echo('<p style="color: green;">'.htmlentities($_SESSION['success'])."</p>\n");
unset($_SESSION['success']);
}
?>
<!-- without login -->
<?php if(!isset($_SESSION['name'])) {
echo '<p><a href="login.php">Please log in</a></p>';
echo '<p>Attempt to <a href="add.php">add data</a> without logging in</p>';
} ?>
<!-- with login -->
<?php if(isset($_SESSION['name'])) {
echo '<table border="1"><thead><tr><th>Make</th><th>Model</th><th>Year</th><th>Mileage</th><th>Action</th></tr></thead>';
$smtp = $pdo->query("SELECT autos_id, make, model, year, mileage FROM autos ORDER BY make");
while ($row = $smtp->fetch(PDO::FETCH_ASSOC)) {
echo("<tr><td><b>");
echo($row['make']);
echo("</b></td><td><b>");
echo($row['model']);
echo("</b></td><td><b>");
echo($row['year']);
echo("</b></td><td><b>");
echo($row['mileage']);
echo("</b></td><td><b>");
echo("<a href=\"edit.php?autos_id=".$row["autos_id"]."\">Edit</a> / <a href=\"delete.php?autos_id=".$row["autos_id"]."\">Delete</a>");
echo("</b></td><tr>\n");
}
echo '</table>';
echo '<p><a href="add.php">Add New Entry</a></p> <p><a href="?logout">Logout</a></p>';
if(isset($_GET['logout'])) {
session_unset();
}
} ?>
</div>
</body>
我面临的问题与链接“注销”有关,如下所示:
echo '<p><a href="add.php">Add New Entry</a></p> <p><a href="?logout">Logout</a></p>';
如果我单击一次,this is the result i get。
这将按预期注销用户,但是我希望它立即reach this page(这是没有登录的index.php),要实现这一点,我必须在链接中单击两次...
Logout.php:
session_start();
unset($_SESSION['name']);
unset($_SESSION['user_id']);
header('Location: index.php');
我该怎么办?

答案 0 :(得分:1)
我已将 Logout.php 更改为:
<?php
session_start();
unset($_SESSION['name']);
unset($_SESSION['user_id']);
header('Location: index.php');
?>
和“登出”链接到:
echo '<p><a href="add.php">Add New Entry</a></p> <p><a href="logout.php">Logout</a></p>';
现在工作正常!

将您的“?logout”替换为logout.php页面的URL,希望它可以解决问题

我在最后添加 session_destroy();
解决了这个问题
<?php
session_start();
unset($_SESSION['loggedin']);
unset($_SESSION['email']);
session_destroy();
?>
