Question

我想知道为什么我们的会话在“login（）”函数中没有被设置。如果我在构造函数或find（）函数中设置会话，则它们已正确设置，但如果我将它们放在login（）函数中，则它们不会被设置。谁能回答我为什么？由于自动加载，会在所有文件中加载会话启动（），因此这是一个问题。

的login.php：

     <?php 
        error_reporting(E_ALL);
        ini_set('display_errors', 1);
        require_once '/home/1/u/someplace/www/Core/init.php';
        if(Input::exists()){
        if(Token::validate(Input::get('token'))){

        $validate = new validator;
        $passed = $validate->validate($_POST, array('email' =>  array('required' => 'true'), 'password' => array('required' => 'true')));

        if ($passed) {

            $user = new users(Input::get('username'));

            if($user->login(Input::get('password')));{

                redirect::to("http://www.someplace.info/Includes/index.php");
            }


        }else{
            echo "not passed";
        }
    }
}
?>

<html>
    <header></header>
<body>

<form action="" method="post">
    <input name="username" value="<?php echo Input::get('email');?>">
    <input name="password" value="<?php echo Input::get('password')?>">
    <input type="hidden" name="token" value="<?php echo Token::generate(); ?>" > 
    <input type="submit" value="Login">
</form>
</body>
</html>

Users.php：

<?php
class users{

    private $_db;
    private $_data = array();
    private $_sessionName;
    private $_cookieName;
    private $_isLoggedIn;
    private $_link;

function __construct($user = null){
    $this->_db = Database::getDBI();
    $this->_cookieName = Config::get('cookie:cookie_name');
    $this->_sessionName = Config::get('session:session_name');

    if (Session::exists($this->_sessionName) && $user == null) {
        $user = Session::get($this->_sessionName); //session = name[user], value = user_id
        //sessions can be put here.
            if($this->find($user)){
                   $this->_isLoggedIn = true;

            } elseif(!$this->_link == "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]") {
                    redirect::to("http://www.ulrikbf.info/includes/login.php");
            }

    } else {
            $this->find($user);

        }
    }

    public function create($table,$field,$values = array()){
    if (!$this->_db->insert($table,$field,$values)) {
        return false;
        }

    }


public function find($user = null){
    //sessions can be put here.

    switch ($user) {
        case is_numeric($user):
                $this->_data = $this->_db->get('users', array('user_id','=',$user));
            break;
        case $user == null:
                $this->_data = $this->_db->get('users', array('email','=',session::get(config::get('session::session_name'))));
            break;
        default:
                $data = $this->_data = $this->_db->get('users', array('email','=', $user));
                $datafirst = $data->first();
                    if ($user == $datafirst->email) {
                    $this->_data = $datafirst;
                    }
            break;
            return $this->_data;
    }
}

public function login($user_password = null){

        $password = hash::make($user_password, $this->_data->salt);
        $passwordHash = $this->_data->password;

            if ($passwordHash == $password ) {

                $hashSession = hash::unique();

                    session::put('hash', $hashSession); //not working
                    session::put($this->_sessionName,$this->data()->user_id); //not working.

            $this->_db->insert('sessions','user_id, hash', array(
            $this->_data->user_id, $hashSession));

                return true;
            }
        return false;
    }

public function data(){
        return $this->_data;
    }

    public function isLoggedIn(){
        return $this->_isLoggedIn;
    }


}

的index.php：

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
require_once '/home/1/u/someplace/www/Core/init.php';

$user = new users();
print_r($_SESSION);
if($user->isLoggedIn()){

echo "Great";

} else {

echo "Not so great";
}



?>

的init.php：

session_start();

//Standard PHP Library(spl)..
spl_autoload_register(function($class)  {
        require_once '/home/1/u/someplace/www/Classes/' . $class . '.php';

});

session.php文件：

<?php
class session {
   public static function put($name,$value){
        return $_SESSION[$name] = $value;

    }
}

您需要在每个文件中启动会话

PHP会话只在我的部分代码中工作？

在session_start（）;
