Ajax和PHP会话

Question

I have a template based site that relies on persistent sessions throughout. Recently I needed to expand the session storage by defining the save handler for database storage. This works fine in the general scope of the classes within the framework however when any of the pages make an ajax request the session id get regenerated and if the form gets submitted the previous session is gone.

  <?php

 require_once('site-database.php');
 require_once('site-config.php');


 class FileSessionHandler

 {


 private $database;

 private $life_time;


 public function FileSessionHandler(){


 $this->life_time = get_cfg_var("session.gc_maxlifetime");

 $this->database = new database();

 $this->database->newConnection(db_host,db_user_name,db_user_pass,db_user_database);


 session_set_save_handler(
array(&$this,'open'),
array(&$this,'close'),
array(&$this,'read'),
array(&$this,'write'),
array(&$this,'destroy'),
array(&$this,'gc')
);

}

Answer 1

Please check whether you have started the session with session_start().
