会话数据ci3基本控制器

标签: php codeigniter session controller base

我在我的控制器命名页面上有这个(我用它作为终端分支到所有视图)

    class pages extends MY_Controller {
    public function verification(){

    $session_data = $this->is_logged_in();
    print_r($session_data);
        if($this->is_logged_in()){


        }
    }
}

正如你所看到的,我在session_data上有一行'print_r',我得到了一些结果,问题是它总是只返回'1'。

这是我的基本控制器上的功能。

class MY_Controller extends CI_Controller {
    public function __construct()
    {
        parent::__construct();
    }

    public function is_logged_in()
    {
        $user = $this->session->userdata();
        return isset($user);
    }  
}

这是在我的身份验证器控制器上创建会话数据登录后的代码块。

Class user_authentication extends MY_Controller {

public function register(){
    $this->form_validation->set_rules('username', 'Username','required|trim|min_length[8]|max_length[24]|is_unique[user.username]',
    array('required' => 'You have not provided %s.','is_unique' => 'This %s already exists.'));
    $this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[8]|max_length[16]');
    $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|min_length[6]|max_length[30]|is_unique[user.email]',
    array('required' => 'You have not provided %s. ','is_unique' => 'This %s already exists.'));
    $this->form_validation->set_rules('type', 'Account Type', 'trim|required|min_length[1]|max_length[1]',
    array('required' => 'please select: 1 - normal, 2 - trainer'));
    $this->form_validation->set_error_delimiters('', '');
        if ($this->form_validation->run() == FALSE){
            $this->load->view('templates/header');
            $this->load->view('templates/navigation');
            $this->load->view('pages/login');
            $this->load->view('templates/footer');
        }else{
            $data = array('username' => $this->input->post('username'),
                          'password' => $this->input->post('password'),
                          'email' => $this->input->post('email'),
                          'type' => $this->input->post('type')); 
            $result = $this->Account_model->create_account($data);
                if($result == true){
                    $data['message_display'] = 'Registration Successful';
                    $this->load->view('templates/header');
                    $this->load->view('templates/navigation');
                    $this->load->view('pages/homepage',$data);
                    $this->load->view('templates/footer');    
                }else{
                    $data['message_display'] = 'Username and/or Email already exists';
                    $this->load->view('templates/header');
                    $this->load->view('templates/navigation');
                    $this->load->view('pages/login',$data);
                    $this->load->view('templates/footer');}
        }
}

public function login(){
$this->form_validation->set_rules('username', 'Username', 'required|trim|min_length[8]|max_length[24]');
$this->form_validation->set_rules('password', 'Password', 'required|trim|min_length[8]|max_length[16]');
    if($this->form_validation->run() == FALSE){
        $this->load->view('templates/header');
        $this->load->view('templates/navigation');
        $this->load->view('pages/login');
        $this->load->view('templates/footer');}
    else{
        $data = array('username' => $this->input->post('username'), 'password' => $this->input->post('password'));
        $result = $this->Account_model->login_account($data);
        $session_data = array('username' => $result['username'], 'email' => $result['email'], 'type' => $result['type']);
        $this->session->set_userdata('isloggedin',$session_data);
        $data['title'] = 'home';
        $this->load->view('templates/header');
        $this->load->view('templates/navigation');
        $this->load->view('pages/home');
        $this->load->view('templates/footer');}
}

现在有些东西基本没用,但是我把它们放在那里以备将来使用。比如$ data ['title']会使用它作为每个视图头部标题的占位符,因为我使用的是模板。

我做错了吗?为什么当我从MY_Controller中打印会话数据时它只返回'1'。

我一直在寻找指南,但大多数已经过时了,我可能会使用过去版本中不推荐使用的东西,如果这样点好点,我想练习编码整洁干净。

2 个答案:

答案 0 :(得分:0)

如果要打印所有会话数据,请使用此

print_r($this->session->all_userdata());

和这部分

public function is_logged_in()
    {
        $user = $this->session->userdata();
        return isset($user);
    }  

将返回1或0;

答案 1 :(得分:0)

您的方法不会以这种方式工作,因为userdata返回一个至少有一个名为 __ ci_last_regenerate 的键的数组(我不确定您使用哪个CI版本但是如果您自动加载会话库你总能得到一个结果)

设置一个额外的密钥 isLoggedin ,你就可以了。

您的登录功能:

public function login()
{
    $this->form_validation->set_rules('username', 'Username', 'required|trim|min_length[8]|max_length[24]');
    $this->form_validation->set_rules('password', 'Password', 'required|trim|min_length[8]|max_length[16]');
    if($this->form_validation->run() == FALSE)
    {
        $this->load->view('templates/header');
        $this->load->view('templates/navigation');
        $this->load->view('pages/login');
        $this->load->view('templates/footer');}
    else
    {
        $data = array('username' => $this->input->post('username'), 'password' => $this->input->post('password'));
        $result = $this->Account_model->login_account($data);

        if ($result)
        {
            $session_data = array('username' => $result['username'], 'email' => $result['email'], 'type' => $result['type'], 'isLoggedin' => true);
            $this->session->set_userdata($session_data);

            $data['title'] = 'home';
            $this->load->view('templates/header');
            $this->load->view('templates/navigation');
            $this->load->view('pages/home');
            $this->load->view('templates/footer');

        }

    }
}

和您的控制器

class MY_Controller extends CI_Controller {
    public function __construct()
    {
        parent::__construct();
    }

    public function is_logged_in()
    {
        return $this->session->userdata('isLoggedin');
    }  
}

使用这种方法,您可以获得正确的值或返回true或false的NULL;
