如何使用公共功能登出

Question

我使用下面的代码注销，我不知道如何使用公共函数注销，如何使用按钮模式和使用函数注销，这是我来自login.php的函数

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Login extends CI_Controller
{

    //this function will do the login process
    function __construct()
    {
        parent::__construct();
        $this->load->library('session');
    }


    function index()
    {
        $this->load->library('session');
        if ($this->session->username != NULL) {
            redirect('index.php/report/dashboard_ch');
        } else {
            $this->load->view('login');
        }
    }



    function do_login()
    {
        $this->load->library('session');
        $this->load->model('M_login');
        $username = $this->input->post('username');
        $password = $this->input->post('password');
        $dataLogin = false;

        if ($username === "dimasdev") {
            $dataLogin = $this->M_login->web_login_hashed($username, $password);
        } else {
            $dataLogin = $this->M_login->web_login($username, $password);
        }

        if (!$dataLogin) {
            $res['msg'] = "Invalid username or password";
            $res['status'] = false;
            echo json_encode($res);
            exit();
        }

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

        $res['msg'] = "Login Success";
        $res['dataLoginUsername'] = $dataLogin['username'];
        $res['status'] = true;
        echo json_encode($res);
    }

    public function logout()
    {
        $this->session->sess_destroy(); // Destroy the session
        $res['msg'] = "Logout Success";
        $res['status'] = true;
        echo json_encode($res);
    }
}

这是我从导航栏注销的模式，我使用按钮注销，但我不知道如何注销

<div class="modal fade" id="logoutModal" tabindex="-1" aria-labelledby="logoutModalLabel" aria-hidden="true">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="logoutModalLabel">Are you sure you want to log out?</h5>
            </div>
            <div class="modal-footer">
                <div class="col s2" style="float: center">
                    <button class="btn btn-danger" href="<?php echo base_url(); ?>index.php/login/logout" class="col s6 modal-close waves-effect waves-green btn-flat yes">OK</button>
                </div>
                <div class="col s2" style="float: center">
                    <button class="btn btn-secondary" data-bs-dismiss="modal" class="col s6 modal-close waves-effect waves-green btn-flat no">Cancel</button>
                </div>
            </div>
        </div>
    </div>
</div>

我使用 vuexy html 框架构建此代码 你能帮忙吗？

Answer 1

只是一个小 HTML 错误。

<a href="URL">LABEL</a>

按钮没有 href 属性，如果您想使用按钮，只需将其用作 LABEL

<a href="URL"><button></button></a>

对于你的情况

<div class="col s2" style="float: center">
    <a href="<?php echo base_url() . "index.php/login/logout"; ?>">
        <button class="btn btn-danger" class="col s6 modal-close waves-effect waves-green btn-flat yes">OK</button>
    </a>
</div>
