会话是有状态的，PHP 用户代码不是 [英] Sessions are stateful, PHP user code is not

问题描述

在验证用户输入并存储登录凭据后，我通过调用 session::start 启动会话，然后通过调用 general::reload 重新加载 index.php 文件.我使用 session::is_start() 来确定从索引文件加载哪个页面.

After validating user input and storing login credentials I start a session by calling session::start and then reload the index.php file by calling general::reload. The I use session::is_start() to determine which page to load from the index file.

我认为这不能正常工作，因为我总是加载相同的页面 - b1e.htm.

I don't think this is working correctly as I always get the same page loaded - b1e.htm.

我担心的是，我的静态类会话在 AJAX/PHP 调用和重新加载 index.php 调用之间没有保持其值.

My concern is that my static class session does not maintain its value between the AJAX/PHP call and the reload index.php call.

index.php

  include 'b2.php'; 

  if(session::is_start())
    {
    include 'b2e.htm';  // user is logged in
    }
  else
    {
    include 'b1e.htm'; // user is not logged it
    }

代码片段 - session:start() 和 session::is_start();

Snippet - session:start() and session::is_start();

class session
  {
  protected static $ses_id ="";
  public static function start()
    {
    self::$ses_id = session_start();
    }
  public static function is_start()
    {
    return self::$ses_id;
    }
  public static function finish()
    {
    self::$ses_id = 0;
    $_SESSION=array();
    if (session_id() != "" || isset($_COOKIE[session_name()]))
      {
      setcookie(session_name(), '', time()-2592000, '/');
      }
    session_destroy();
    }
  }

代码段 - 常规::reload()

Snippet - general::reload()

class general
  {
  public static function reload()
    {
    $uri = 'http://';
    $uri .= $_SERVER['HTTP_HOST'];
    header('Location: '.$uri.'/host_name');
    }

推荐答案

您需要调用您的 session_start(); 以在每个页面上实际启动会话.

You need to call your session_start(); to actually start the session on each page.
