Label in Form Validation

PHP Code:

public function email_agreement()
    {
        $messages = [
            'notice_email' => [
                'required' => 'Email is required',
                'valid_email' => 'Email is invalid',
            ],
        ];
        $this->validation->setRules([
            'notice_email' => 'required|valid_email',
        ], $messages);

        if ($this->request->getPost('submitted') == null || 
                ! $this->validation->withRequest($this->request)->run()) {
            print view('header', [
                'current' => 'register', 
                'title' => 'Email Agreement', 
                'session' => $this->session,
            ]);
            print view('email_agreement', [
                'validation' => $this->validation, 
                'session' => $this->session,
                'confirm' => $this->request->getGet('confirm'),
            ]);
            print view('footer');
        } else {
            $this->session->set($this->request->getPost());
            $confirm = $this->request->getPost('confirm');
            if ($confirm == 'yes')
                redirect('/register/confirm_input');
            else
                redirect('/register/subscriber_and_contact_info');
        }
    }
