Password hashing

You must retrieve the password in the database by username, then use password_verify to compare two passwords.

PHP Code:

// code to login
$username = $this->input->post('username');
$password = $this->input->post('password');

$access = $this->user->login_access($username, $password);

//
function login_access($username, $password)
{
    $query = $this->db->get_where('USER_NAME', $username);
    if ($query->num_rows() > 0)
    {
        $user_row = $query->row();
        return password_verify($password, $user_row->PASSWORD);
    }
    
    return FALSE;
}
