PHP 重定向不起作用，会话已启动 [英] PHP Redirection not working, session has been started

问题描述

我试图让 PHP 重定向在登录表单中工作，但是，它不起作用.这是验证成功的代码.

I'm trying to get PHP redirection to work, in a login form, however, it is not working. Here's the code if the authentication is successful.

$success = (isset($_POST['uri'])) ? '' : '/index.php';

if ($rs->num_rows) {

    $qn = $db->query("SELECT userid FROM sessions");
    $svt = array();
    $vbs = $rs->fetch_assoc();

    while ($row = $qn->fetch_assoc()) {
        $svt [] = $row ['userid'];
    }

    if (in_array($vbs ['userid'], $svt)) {
    } else {
        set_session(array_merge($vbs, array('expires' => time() + (30 * 60))));
        $_SESSION['secure3d']['expires'] = time() + (5 * 60);
        header("Location: $success"); // this isn't working but the session is set.
    }
}

对我在这里做错了什么有什么想法吗?

Any ideas on what I'm doing wrong here?

推荐答案

尝试将 $success 作为绝对 URI，例如 http://mydomain.com/index.php 例如在 http/1.1 中，它必须是绝对 URI

Try $success as an absolute URI, something like http://mydomain.com/index.php e.g. in http/1.1 it has to be an absolute URI

另一个流行的错误是在头函数之前发送了一个空格.如果您有一个以 "?>"

Another popular error is that an whitespace is send before the header function. This can be happen if you have an include which ends with "?> "
