setcookie("user_id",$user_info['user_id'],86500); setcookie("username",$user_info['username'],86500); setcookie("password",$user_info['password'],86500); //echo $_COOKIE['username'];
$this->input->set_cookie("username",$user_info['username'],60); $this->input->set_cookie("password",$user_info['password'],60); $this->input->set_cookie("user_id",$user_info['user_id'],60); //echo $this->input->cookie("password");//适用于控制器 //echo $this->input->cookie("username");//适用于控制器 //echo $_COOKIE['username'];//在模型类中可以通过这种方式获取cookie值 //echo $_COOKIE['password'];//在模型类中可以通过这种方式获取cookie值
set_cookie("username",$user_info['username'],60); set_cookie("password",$user_info['password'],60); set_cookie("user_id",$user_info['user_id'],60); //echo get_cookie("username");
例子自定义扩展核心控制器类
<?php class MY_Controller extends CI_Controller{ //构造函数:在构造函数中判断用户是否已经登陆,如果登陆,可进入后台控制器,返回跳转到登陆页面 public function __construct(){ parent::__construct(); $this->load->helper("url"); $this->load->model("user_model");//user_model模型类实例化对象 $this->cur_user=$this->user_model->is_login();//检测是否登陆,如果登陆,返回登陆用户信息,否则返回false if($this->cur_user === false){ header("location:".site_url("index/login")); }else{ //如果已经登陆,则重新设置cookie的有效期 $this->input->set_cookie("username",$this->cur_user['username'],60); $this->input->set_cookie("password",$this->cur_user['password'],00); $this->input->set_cookie("user_id",$this->cur_user['user_id'],60); } } } ?>
希望本文所述对大家基于CI框架的PHP程序设计有所帮助。
