my controller

PHP Code:

public function login()
        {
            if($this->request->getPost('email')) {
                $username = $this->request->getPost('email');
                $pass     = $this->request->getPost('pass');
                
                redirect()->to(base_url('dasboard'));
                }
                return view('login');
            } 


when i click button submit, it go to file logincontroller but input email, pass dont working and go to 404 page not found

please, show me how to fix it

You need to fill in the form action to tell it where to go in the controller/method.

PHP Code:

// controller/method = your controller and the method to run.
<form class="form-signin form-group" role="form" method="post" action="<?= base_url('controller/method');?>"> 


Try that.

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

Not looked properly but forms need an action, unless you're passing that via ajax, and CRSF protection.
