还记得跨页面的字段吗？

发布于 2024-10-31 23:25:39 字数 638 浏览 4 评论 0原文

我有这个： main.php：

ID: <input name="id" id="id" type="text" size="20" value="<?php echo $_POST['id']; ?>"><br>
Password: <input name="password" id="password" type="password" value="<?php echo $_POST['password']; ?>" size="20">

文件main.php是索引页。

文件 main.php 是一个带有 action="main.php" 的表单，

当我从 main.php 转到 console.php 时，我没有得到值 id 和密码。

当我从 main.php 转到plugins.php 时，我没有得到值 id 和密码。

从main.php，您可以进入plugins.php 和console.php。但那时你并没有得到这些值。

我知道为什么会这样。

如何解决这个问题？我怎样才能使当我转到console.php或plugins.php时，这些字段将被记住？

课程对我来说太难学了。还有其他解决办法吗？

原文

I have this:
main.php:

ID: <input name="id" id="id" type="text" size="20" value="<?php echo $_POST['id']; ?>"><br>
Password: <input name="password" id="password" type="password" value="<?php echo $_POST['password']; ?>" size="20">

File main.php is index page.

File main.php is a form with action="main.php"

When i go from main.php to console.php, i dont get the values id and password.

When i go from main.php to plugins.php, i dont get the values id and password.

From main.php, you can get into plugins.php and console.php. But you don't get the values then.

I know why it happens.

How to fix this? How can i make, that when i go to console.php, or plugins.php, the fields will stay remembered?

Sessions are too hard for me to learn. Is there any other solution?

太难了？简而言之，在您想要使用会话的每个页面的顶部，使用 session_start()。现在，您想将某些内容保存到会话中吗？

#page1
session_start();
$_SESSION['foo'] = 'bar';

#page2
session_start();
echo $_SESSION['foo'] #echoes bar

unset($_SESSION['foo']); #destroy foo
#if you want to discard the entire session, use
session_destroy(); #going down!

所以，在你的情况下，也许是这样的：

#main.php
session_start();
if (isset($_POST['id'], $_POST['password'])) {
    $_SESSION['id'] = $_POST['id'];
    $_SESSION['password'] = $_POST['password'];
}
#rest of main.php

#console.php and plugins.php
session_start();
if (isset($_SESSION['id'], $_SESSION['password']))
    #do stuff

我觉得用勺子喂你很糟糕，但基本的会话功能确实是你所描述的情况所需要的，而且它可能是传递敏感信息的最简单的方法，这基本上就是会议的目的。

欲了解更多信息：

Too hard? Put simply, at the top of every page you want to use sessions with, use session_start(). Now, you want to save something to a session?

#page1
session_start();
$_SESSION['foo'] = 'bar';

#page2
session_start();
echo $_SESSION['foo'] #echoes bar

unset($_SESSION['foo']); #destroy foo
#if you want to discard the entire session, use
session_destroy(); #going down!

So, in your case, maybe something like:

#main.php
session_start();
if (isset($_POST['id'], $_POST['password'])) {
    $_SESSION['id'] = $_POST['id'];
    $_SESSION['password'] = $_POST['password'];
}
#rest of main.php

#console.php and plugins.php
session_start();
if (isset($_SESSION['id'], $_SESSION['password']))
    #do stuff

I feel bad for spoon-feeding you with it, but basic session functionality is really all that's needed in the case you're describing, and it's probably the easiest way to pass around sensitive info, and is basically what sessions were made for.
