Give your code controller

Give your code controller

Thanks for your reply.

The file session handler works, but the session database handling throws an error.

$sessionData = array(
'emp_id' => $row['emp_id']
);

$this->Session->set($sessionData );

Share your code that is responsible to initialize the $this->Session.
And if possible then share your whole controller code.

I got an error trying to handle the session database.
File handling works well in my code.

[app\Controllers\LoginController.php]

[app\Services\AuthService.php]
=> It's a library file that I made.

[vendor\codeigniter4\framework\system\Session\BaseHandler.php]
=> error

Fatal error

I'm really sorry.
I made a mistake because I am a beginner in writing.
I don't have the current source code. Screenshot is everything.

Thank you so much for your concern.

I tried this and it was solved.

@int_set('session.save_path',$this->savePath);
