如何在codeigniter中将用户ID设置为会话数组？

Question

我对 Codeigniter 有点陌生，所以我需要一些帮助，如果你可以在这里发布答案，请。谢谢。

这是我的控制器：

public function login()
{

    $this->load->library('form_validation');

    $this->form_validation->set_rules('email', 'Email', 'required|valid_email|min_length[3]');
    $this->form_validation->set_rules('passwd', 'Passwd', 'required|min_length[3]');

    $data = array();

    if ($this->form_validation->run())
    {
        $email = $this->input->post('email');
        $passwd = $this->input->post('passwd');

        $this->load->model('user_model');

        if ($this->user_model->check($email, $passwd))
        {

            $this->session->set_userdata('user', $email);

            redirect(base_url('/'));
        }
        else
        {
            $data['error'] = 'Wrong e-mail or password.';
        }
    }

    $this->load->view('login', $data);
}

这是我的模型：

public function __construct()
{
    // Call the CI_Model constructor
    parent::__construct();
}

public function check($email = NULL, $password = NULL)
{
    $this->db->select('id');
    $this->db->where('email', $email);
    $this->db->where('password', sha1($password));
    $this->db->limit(1);
    $result = $this->db->get('php_users_login');

    return ($result->num_rows() == 1);
}

我想将用户 ID 放入会话中（数据库结构，如 ID、电子邮件、密码...）

感谢您的帮助！

Answer 1

试试这个

型号

$this->db->select('id');
$this->db->where('email', $email);
$this->db->where('password', sha1($password));
$this->db->limit(1);
$result = $this->db->get('php_users_login');
return   $result->row();

控制器

$checkData=$this->user_model->check($email, $passwd);
if(count($checkData)==1){
   $this->session->set_userdata('user_id', $checkData->id);
}

试试这个

在控制器中

public function login()
{

    $this->load->library('form_validation');
    $this->load->model('user_model');

    $this->form_validation->set_rules('email', 'Email', 'required|valid_email|min_length[3]');
    $this->form_validation->set_rules('passwd', 'Passwd', 'required|min_length[3]');

    $data = array();

    if ($this->form_validation->run())
    {
        $email = $this->input->post('email');
        $passwd = $this->input->post('passwd');         

        $result = $this->user_model->check($email, $passwd);

        if ($result == true)
        {
            $newdata = array(
               'email'     => $email,
               'logged_in' => TRUE
           );

            $this->session->set_userdata($newdata);

            $this->load->view('home', $data); # load view
        }
        else
        {
            $data['error'] = 'Wrong e-mail or password.';
            $this->load->view('login', $data);
        }
    }
    else{
        echo "Form validation Error";
    }

}

在模型中

public function check($email, $password)
{

    $query = $this->db->query("SELECT * FROM php_users_login WHERE email = '$email' AND password = sha1('$password') ");
    $result = $query->result_array();

    $count = count($result);

    if (empty($count) || $count > 1 ) {
        return false;
    }
    else{
        return true;
    }
}

你可以在 session 中设置 userid 为：

在你的模型中使用它：

public function check($email = NULL, $password = NULL)
{
    $userid = 0;
    $this->db->select('id');
    $this->db->where('email', $email);
    $this->db->where('password', sha1($password));
    $this->db->limit(1);
    $result = $this->db->get('php_users_login');

    if($result->num_rows() == 1){
        $data = $query->result_array();
        $userid = $data[0]['id'];
    }
    return $userid;
}

在控制器中：

// if login successfull
$this->load->model('user_model');
$userid = $this->user_model->check($email, $passwd);
if ($userid > 0)
{
    // session array
    $session_data = array(
           'session_userid'  => $userid,    
           'session_email'  => $email
           );

    $this->session->set_userdata($session_data);
    redirect(base_url('/'));
}
else
{
    $data['error'] = 'Wrong e-mail or password.';
}

旁注：

我没有看到您的代码中包含会话库，请确保您在 autoload.php 中使用或包含在同一控制器中。

$this->load->library('session');
