PHP header(Location: ...)：强制地址栏中的URL更改

PHP header(Location: ...): Force URL change in address bar

提问by vemoxy

I'm currently working on a mobile site with authentication using PHP sessions with a database. I have a login page with a form that goes to server_login.phpon submit. The php file then creates some session data (store in $_SESSION), and redirects the user back to the index page:

我目前正在使用带有数据库的 PHP 会话进行身份验证的移动站点。我有一个登录页面，其中包含一个在提交时转到server_login.php的表单。php 文件然后创建一些会话数据（存储在 $_SESSION 中），并将用户重定向回索引页面：

header("location:../../index.php");

The new web page (index.php) loads correctly; however, when the header redirects the page, the URL at the address bar is not changed; it stays at *http://localhost/php/server/server_login.php* instead of http://localhost/index.phpand thus all my other resources that makes use of relative pathing could not be loaded. It's as if the web page still thinks that it resides at /php/server instead of /.

新网页 (index.php) 正确加载；但是，当header重定向页面时，地址栏的URL并没有改变；它停留在 *http://localhost/php/server/server_login.php* 而不是http://localhost/index.php，因此我所有其他使用相对路径的资源都无法加载。就好像网页仍然认为它驻留在 /php/server 而不是 /。

Strangely, my other use of header("location: ...") at logout.php works and redirects the page successfully with a URL change.

奇怪的是，我在 logout.php 中使用 header("location: ...") 的其他用法可以通过更改 URL 成功地重定向页面。

I've made sure that there are no outputs in my *server_login.php* before the header redirect (above it are just mysql calls to check) and I've used ob_start() and ob_end_flush() too.

我已经确保在头重定向之前我的 *server_login.php* 中没有输出（上面只是要检查的 mysql 调用），并且我也使用了 ob_start() 和 ob_end_flush()。

Are there any methods of forcing the URL on the address bar to change (and thus hopefully fix the relative path problem)? Or am I doing something wrong?

是否有任何方法可以强制更改地址栏上的 URL（从而有望解决相对路径问题）？还是我做错了什么？

P/S: I am using jQuery Mobile.

EDIT: Here's my code for the redirection that doesn't change the URL:

编辑：这是我的重定向代码，不会更改 URL：

// some other stuff not shown


$sql = "SELECT * FROM $user_table WHERE email = '$myemail' AND password = '$mypassword'";
$login_result = mysql_query($sql, $connection);

$count = mysql_num_rows($login_result);

if ($count == 1) {

    // Successfully verified login information

    session_start();

    if (!isset($_SESSION['is_logged_in'])) {
        $_SESSION['is_logged_in'] = 1;
    }

    if (!isset($_SESSION['email'])) {
        $_SESSION['email'] = $myemail;
    }
    if (!isset($_SESSION['password'])) {
        $_SESSION['password'] = $mypassword;
    }

    // Register user's name and ID
    if ((!isset($_SESSION['name'])) && (!isset($_SESSION['user_id'])))  {
        $row = mysql_fetch_assoc($login_result);
        $_SESSION['name'] = $row['name'];
        $_SESSION['user_id'] = $row['user_id'];
    }

    header("Location: http://localhost:8080/meet2eat/index.php");

} else {
    // Not logged in. Redirect back to login page
    header("Location: http://localhost:8080/meet2eat/php/login.php?err=1");

}

尝试改变：

header("Location : blabla")
                ^
                |
           (whitespace)

To

到

header("Location: blabla")

Well, if the server sends a correct redirection header, the browser redirects and therefore "changes the url". It might be a browser issue, then. I don't know if it has anything to do with it, but you should not send a relative url in the location header ("HTTP/1.1 requires an absolute URI as argument to ? Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. ", http://php.net/manual/en/function.header.php), and "location" must be capitalized, like:

好吧，如果服务器发送正确的重定向标头，浏览器会重定向并因此“更改 url”。那么可能是浏览器的问题。我不知道它是否与它有什么关系，但是您不应该在位置标头中发送相对 url（“HTTP/1.1 需要一个绝对 URI 作为参数？位置：包括方案、主机名和绝对路径，但有些客户端接受相对 URI。", http://php.net/manual/en/function.header.php)，并且 "location" 必须大写，例如：

header('Location: http://myhost.com/mypage.php');

In your form element add data-ajax="false". I had the same problem using jquery mobile.

在您的表单元素中添加data-ajax="false". 我在使用 jquery mobile 时遇到了同样的问题。

Do not use any white space. I had the same issue. Then I removed white space like:

不要使用任何空白。我遇到过同样的问题。然后我删除了空格，如：

header("location:index.php"); or header('location:index.php');

Then it worked.

然后它起作用了。

I had the same problem with posting a form. What I did was that turning off the data-ajax.

我在发布表单时遇到了同样的问题。我所做的是关闭数据ajax。

you may want to put a break; after your location:

你可能想休息一下；在您的位置之后：

header("HTTP/1.1 301 Moved Permanently");
header('Location:  '.  $YourArrayName["YourURL"]  );
break;

回答by shlgug

As "cfphpflex" suggested you can add break;after setting the header. You can also echo something, such as echo 'test';.

正如“cfphpflex”所建议的，您可以break;在设置标题后添加。您还可以回显某些内容，例如echo 'test';.

// Register user's name and ID

// 注册用户名和ID

if ((!isset($_SESSION['name'])) && (!isset($_SESSION['user_id'])))  {
    $row = mysql_fetch_assoc($login_result);
    $_SESSION['name'] = $row['name'];
    $_SESSION['user_id'] = $row['user_id'];
}

header("Location: http://localhost:8080/meet2eat/index.php");

change to

改成

// Register user's name and ID

// 注册用户名和ID

if ((!isset($_SESSION['name'])) && (!isset($_SESSION['user_id'])))  {
    $row = mysql_fetch_assoc($login_result);
    $_SESSION['name'] = $row['name'];
    $_SESSION['user_id'] = $row['user_id'];
header("Location: http://localhost:8080/meet2eat/index.php");
}

回答by Joe Barbour

Are you sure the page you are redirecting too doesn't have a redirection within that if no session data is found? That could be your problem

如果未找到会话数据，您确定要重定向的页面也没有重定向吗？那可能是你的问题

Also yes always add whitespace like @Peter O suggested.

另外是的，总是像@Peter O 建议的那样添加空格。

I got a solution for you, Why dont you rather use Explode if your url is something like

我为你找到了一个解决方案，如果你的 url 是这样的，你为什么不宁愿使用 Explode

Url-> website.com/test/blog.php

网址-> website.com/test/blog.php

$StringExplo=explode("/",$_SERVER['REQUEST_URI']);
$HeadTo=$StringExplo[0]."/Index.php";
Header("Location: ".$HeadTo);
