Here is my code for controller

Code:

function login()
        {
            $this->load->view('login');
        }
      
        function logval()
        {
            $this->form_validation->set_rules('usr','Username','required');
            $this->form_validation->set_rules('pass','Password','required');
    
            if($this->form_validation->run() == FALSE)
            {
                $this->load->view('login');
            }
            else
            {
                $data['usr'] = $this->input->post('usr');
                $data['pass'] = $this->input->post('pass');
                
              if($this->user_model->check_login($data)== TRUE)
                {
                //$this->load->view('home');
                  return TRUE;
                }
                else
                {
                 //$this->load->view('failure');  
                  return FALSE;  
                }
            }
        
        }

and here is my code for model

Code:

function check_login($data)
    {

        $username=$data['usr'];
        $password=$data['pass'];

            $query = $this->db->select('uname, pass');
            $query = $this->db->from('users');
            $query = $this->db->where('uname', $username);
            $query = $this->db->where('pass', $password);
//            $query = $this->db->where('Password_VC', $password);
            $query = $this->db->get();

            if($query->num_rows() > 0)
            {
                return true;
                //return $query->result();
            }
            else
            {
                return false;
            }
        }
