你好
我正在处理一些旧代码，其中包括用于用户注册/登录的模块.有一个查询数据库的块，以查看用户是否已登录，然后重定向到登录页面.
I am working with some legacy code that includes a module for user registration / login. There is a block that queries the DB to see if the user is logged in, then re-directs to the login page.
重定向由<meta http-equiv='refresh' content='=2;index.php' />处理，但是自那以后我就知道它已被贬值，并且在所有浏览器中均不起作用.
The re-direct is handled by <meta http-equiv='refresh' content='=2;index.php' /> but I have since learnt this is depreciated, and doesn't work in all browsers.
是否有另一种方法可以在下面的代码中放置重定向?
Is there an alternative way to put a re-direct within the code below?
$username = mysql_real_escape_string($_POST['username']);
$password = md5(mysql_real_escape_string($_POST['password']));
$checklogin = mysql_query("SELECT * FROM users WHERE username = '".$username."' AND password = '".$password."'");
if(mysql_num_rows($checklogin) == 1)
{
$row = mysql_fetch_array($checklogin);
$email = $row['email'];
$_SESSION['username'] = $username;
$_SESSION['email'] = $email;
$_SESSION['LoggedIn'] = 1;
echo "<h1>Success</h1>";
echo "<p>We are now redirecting you</p>";
echo "<meta http-equiv='refresh' content='=2;index.php' />";
}
else
{
echo "<h2>Error</h2>";
echo "<p>Sorry, your account could not be found. Please <a href=\"index.php\">click here to try again</a>.</p>";
}
非常感谢您提出任何建议.
Many thanks for any pointers.
推荐答案
不建议使用META刷新.您的刷新标签有一个额外的=.应该是
META refresh is not deprecated. Your refresh tag has an extra =. It should be
<meta http-equiv='refresh' content='2;index.php' />
您也可以使用标题进行刷新:
You can do a refresh with a header too:
header("Refresh: 2;index.php");
或使用302重定向:
header("Location: /index.php");
或者用Java语言完成.
Or do it in Javascript.
最好的方法是什么?在<head>部分中使用META刷新标签.这样做的理由是，IE在使用页面的缓存版本时不会保存标头.
And the best method? Use a META refresh tag in the <head> section. Rationale for this is that IE does not save headers when it uses cached version of a page.
