I have to run some condition in every controller

I have to run some condition in every controller. i have posted my code below. now i use __construct 
how can i make it more nicely. now the full code i have to put in every controller but i want to make it other easier way.
Please help i am new in codeigniter but nowdays i loving it. i saw codeigniter before 10 years ago but i ignore it because thats time i was new in php.

PHP Code:

protected $request;
 public function __construct(){
 helper(['url', 'form', 'device', 'cookie']);
 parse_str($_COOKIE['siteAuth'], $output);
   $cookieHash = $output['hash'];
   $usrs = $output['usr'];
 $usersModel = new \App\Models\UsersModel();
 $userdata = $usersModel->where('username', $usrs)->first();
 $dbsid = $userdata['sid'];
 $username = $userdata['username'];
 if(!session()->has('pinverify')) {
 if(get_cookie('siteAuth', true) != null AND ($usrs == $username) AND ($cookieHash == $dbsid)) {
 header('Location: /auth/twosec');
 exit;
 } else {
 header('Location: /auth/signout');
 exit;
 }
 }

    $devicedata = device();
    if (session()->has('pinverify')){
 $this->request = \Config\Services::request();
      $userid = session()->get('user_id');
      $deviceModel = new \App\Models\DeviceModel();
      $isnew = $deviceModel->where('uid', $userid)->countAllResults();
 $agent = $this->request->getUserAgent();
 $browser = $agent->getBrowser().' '.$agent->getVersion();
 $osinfo = $agent->getPlatform();
    $deviceinfo = str_replace(' ', '', $agent);
   if ($isnew == 0) {
 $devicedata = [
 'uid' => $userid,
 'deviceName' => $deviceinfo,
   'browser' => $browser,
   'osname' => $osinfo,
 'lock_status' => '1',
 'country' =>$devicedata['country'],
 'state' =>$devicedata['countrystate'],
 'isp' =>'ispdata',
 'ip' => $this->request->getIPAddress(),
 ];
 if ($deviceModel->insert($devicedata) == true){
 return true;
 }

 } else {
 $device_info = $deviceModel->find($userid);
   $devicedbname = $device_info['deviceName'];
   $device_status = $device_info['lock_status'];
   if ($device_status == 0){

 $devicedata = [
 'uid' => $userid,
 'deviceName' => $deviceinfo,
   'browser' => $browser,
   'osname' => $osinfo,
 'lock_status' => '1',
 'country' =>$devicedata['country'],
 'state' =>$devicedata['countrystate'],
 'isp' =>'ispdata',
 'ip' => $this->request->getIPAddress(),
 ];
 if($deviceModel->update($userid, $devicedata) == true){
 return true;
 }
 }else{
 if ($deviceinfo == $devicedbname){
 return true;
 }else{
 header('Location: /auth/signout');
 exit;
 }
 }

 }

 }

 } 


Hi @mostafiz80 and a warm welcome to the forums.

I have similar problems which I resolve by ensuring all Controllers extend BaseController:

PHP Code:

class C_home extends BaseController 


In BaseController use the following method:
file: ./app/Classes/BaseController

PHP Code:

public function initController
(
    RequestInterface  $request, 
    ResponseInterface $response, 
    LoggerInterface   $logger
)
{
# Do Not Edit This Line
    parent::initController($request, $response, $logger);

# John Added $data
    $this->data = [
      'test_001' => 'TEST to see if it works - 001',
      'test_002' => 'TEST to see if it works - 002',
      'test_003' => $this->common_function_with_data(),
];

}//

private function common_function_with_data()
{
  return  'COMMON DATA GOES HERE';
}// 


To test try this in your common View/vheader menu or common View/vFooter:

PHP Code:

echo '<h6>' .$test_001 .'</h6>';
echo '<h6>' .$test_002 .'</h6>';
echo '<h6>' .$test_003 .'</h6>'; 


initController.its better _constructor

I would recommend you look into Filters: https://codeigniter.com/user_guide/incom...lters.html

Thanks all of you guys for help. i have done using library. i like to use library. 
Now i am stuck in Mysql transaction. The mysql LOCK IN SHARE MODE how will work this query if i use codeigniter transaction. i have to do some transaction on my application.

Transaction lock and unlock the tables , what you have to watch for is dead locks.

To fix dead locks use small optimized queries.

What did you Try? What did you Get? What did you Expect?
