Question

我创建了以下场景。

我有index.php文件，显示主页。在此，有两个字段 - 用户ID和密码包含在表单标记中。提交按钮调用login.php文件。
Login.php验证用户ID，密码等
验证成功后，我希望login.php页面带我到MyDashboard.php页面（传递用户ID和密码）。

我在PHP中尝试过Header但是没有用。我还试图做一个Javascript window.location.href并尝试在$（document）.ready上调用它，但没有任何反应。

请帮忙。

Answer 1

您应该使用会话变量在登录会话中存储变量。不建议也不要将密码传递给其他页面。阅读Sessions，并查看已有的登录脚本。下面是非常简单的示例，使用header() function重定向到下一页。

<?php

// Validate user credentials and save to session
session_start();
$_SESSION['userId'] = $userId;

// Redirect to next page
header("Location: dashboard.php");

// Make sure that code below does not get executed when we redirect
exit;

?>

Answer 2

如果用户通过身份验证，在PHP中：

header('Location:MyDashboard.php');

Answer 3

尝试include()

此功能允许您包含来自其他PHP脚本的代码。

Answer 4

标题功能是正确的方法。只要在调用头函数之前没有任何输出，它就应该有效。

http://us3.php.net/manual/en/function.header.php

发布你的代码，让我们看看它是什么不起作用！

Answer 5

标题应该适合你的情况。

您可以使用以下代码：

header("Location:filename");
exit();

使用第一个中的变量重定向到另一个页面
