$_SESSION 变量没有通过，也不知道为什么?它设置然后没有通过 [英] $_SESSION variable not passing and no clue why? it sets then doesn't pass

问题描述

我有一个用 php 和 mysqli 编写的登录脚本.提交并成功验证后，它会重定向到 success.php 以编写会话.我的成功页面如下所示.

I have a login script coded in php and mysqli. upon submission and successful authentication it redirects to success.php to write sessions. my success page looks like this.

<?php  
 /**
     * Set cookies here if/as needed.
     * Set session data as needed. DO NOT store user's password in
     * cookies or sessions!
     * Redirect the user if/as required.
     */

     $id = $_GET['id'];

    $_SESSION['partner_id']       = $id;
    $_SESSION['authenticated'] = TRUE;

    if (isset($_SESSION['partner_id'])) {
    echo("<script>
    <!--
    location.replace(index.php);
    -->
    </script>");

    }

    else {
        print "Session partner id not set";
    }

?>

此页面有效地重定向到我的 index.php 页面.但是我的索引 php 无法识别会话变量.

This page effectively redirects to my index.php page. However my index php does not recognize the session variable.

    <?php
 session_start();
 // rest of code
print "ths is the session var".$_SESSION['partner_id'];
    ?>

即在文档类型声明之前的页面顶部.

that is at the top of the page before the doctype declaration.

在页面上我也有

<?php 
        if(isset($_SESSION['partner_id'])) {
        print "This is the session id variable".$_SESSION['partner_id']; 
        }

        else {
        print "Session not set";
        }

        ?>

顶部的支票打印为空白，底部的支票打印会话未设置....

The top check prints blank and the bottom one prints session not set....

我很困惑...

推荐答案

您需要在所有使用 $_SESSION 的页面上使用 session_start()

You need session_start() on all pages using $_SESSION

  <?php  
 /**
 * Set cookies here if/as needed.
 * Set session data as needed. DO NOT store user's password in
 * cookies or sessions!
 * Redirect the user if/as required.
 */
 session_start();

 $id = $_GET['id'];

$_SESSION['partner_id']       = $id;
$_SESSION['authenticated'] = TRUE;

另外……你确定 $_GET['id'] 中有值吗?

Also...are you sure that $_GET['id'] has a value in it?

而且....您的表单使用的是 POST 还是 GET?

And....is your form using POST or GET?

我以前犯过那个愚蠢的错误，其中表单使用 POST，而我使用 GET 检索变量并感到沮丧.只是一种可能

Ive made that silly mistake before , where form was using POST and I was retrieving variable with GET and getting frustrated. Just a possibility
