Question

我想知道如何在用户登录时更改在线用户状态。我一直在寻找这个，但我的问题没有答案。我是新学习这个代码的人，所以，我希望你们能为我的问题提供帮助。

控制器：

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.setViewport({width: 1440, height: 2000});
  await page.goto(`https://www.southwest.com/air/check-in/review.html?confirmationNumber=${process.argv[2]}&passengerFirstName=${process.argv[3]}&passengerLastName=${process.argv[4]}`, {
    waitUntil: 'networkidle2'
  });
  [ confirmationNumber, checkinButtonText ] = [ await page.$eval('.confirmation-number--code', el => el.innerHTML), await page.$eval('.actionable_primary.actionable_large-button', el => el.innerHTML) ]
  console.log(checkinButtonText);
  console.log(confirmationNumber);
  await page.click('.actionable_primary.actionable_large-button');
  // The below line makes a click on the button
  await page.click('.air-check-in-boarding-pass-options .boarding-pass-options--button-email, .air-check-in-boarding-pass-options .boarding-pass-options--button-print, .air-check-in-boarding-pass-options .boarding-pass-options--button-text');
  await browser.close();

})();

型号：

public function signdevice() {
    $device = $this->input->post('device');
    $pass = $this->input->post('password');
    $data = array(
        'device'   => $device,
        'password' => $pass,
        'status'   => $status
    );
    $status = 1;
    $res = $this->db->get_where('devices', $data);
    if ($res->num_rows() > 0) {
        $this->session->set_userdata(
            array(
                'signin' => TRUE,
                'device' => $device,
                'status' => $status
            )
        );
        $data = array('device' => $device, 'password' => $pass, 'status' => 1);
        $this->db->where('device', '$device');
        $this->db->update('devices', $data);
        redirect(base_url('pelanggan'));
    } else {
        $this->session->set_flashdata('result_login', 'Wrong Username or Password.');
        redirect(base_url());
    }
}

你有几行失踪＆amp;错误的代码。

控制器：

public function signdevice() {
    $device = $this->input->post('device');
    $pass = $this->input->post('password');
    $data = array(
        'device'   => $device,
        'password' => $pass,
        'status'   => 0 // changed value to 0
    );
    $status = 1;
    $res = $this->db->get_where('devices', $data);
    if ($res->num_rows() > 0) {
        $this->session->set_userdata(
            array(
                'signin' => TRUE,
                'device' => $device,
                'status' => $status
            )
        );
        $data = array('device' => $device, 'password' => $pass, 'status' => 1);
        $this->db->where('device', $device); // removed quotes
        $this->db->update('devices', $data);
        redirect(base_url('pelanggan'));
    } else {
        $this->session->set_flashdata('result_login', 'Wrong Username or Password.');
        redirect(base_url());
    }
}

型号：

...
function update($id,$stat)
{
    $stat = 1; // swapped this line with below
    $data['status'] = $stat; // swapped this line with above
    $this->db->where('kd_device', $id);
    $this->db->update('devices', $data); // maybe what you want to save is $data?
    return TRUE;
}
