无法通过CodeIgniter中的会话登录获取和显示数据名称

Question

因此，我想创建一些登录页面，然后在登录成功后在仪表板上显示用户名。但是名称不会显示在仪表板上。它只是空白。没有错误通知之类的。请帮忙。谢谢

我在PHP 7上运行

Auth.php控制器

public function index()

{

    $this->form_validation->set_rules('email','email',

        'trim|required|valid_email');

    $this->form_validation->set_rules('password','Password','trim|required');

    if($this->form_validation->run() == false){

        $data['title']='Login Page';

        $this->load->view('templates/auth_header', $data);

        $this->load->view('auth/login');

        $this->load->view('templates/auth_footer');

    }

    else{

        //success validation

        $this->_login();

    }

}

private function _login()

{

    $email = $this->input->post('email');

    $password = $this->input->post('password');

    $user = $this->db->get_where('user',['email' => $email])->row_array();

    if($user){

        //user active

        if($user['is_active']==1){

            //check password

            if(password_verify($password, $user['password'])){

                //if pass were right

                $data = [

                    'email' => $user['email'],

                    'role_id' => $user['role_id']

                ];

                $this->session->set_userdata('$data');

                redirect('user');

            }

            else{

                $this->session->set_flashdata('message','<div class="alert alert-danger" role="alert"> Wrong password</div>');

                redirect('auth');

            }

        }

        else{

        //

        $this->session->set_flashdata('message','<div class="alert alert-danger" role="alert"> 

            Email has not been activated</div>');

        redirect('auth');

    }

    }

    else{

        //no email in database

        $this->session->set_flashdata('message','<div class="alert alert-danger" role="alert"> 

            Email is not registered</div>');

        redirect('auth');

    }

}

和用于在页面中显示数据的命令

Answer 1

也许您的错误是Auth-> _ login（）行中的Here&nbsp;set_userdata，请替换$this->session->set_userdata('$data');和$this->session->set_userdata($data);
