    $someone = $this->Student->findByStudentEmail($this->data['Student']['email']); 
    if(!empty($someone['Student']['student_pwd']) && $someone['Student']['student_pwd'] == $this->data['Student']['password']) { 

     $this->Session->write('eyeColor', 'Green'); 
     $this->Session->write('Student', $someone['Student']); 

     // session information to remember this user as 'logged-in'. 
     echo "success"; 

    } else {

    } 
} 
function main(){ 
    $this->set('students', $this->Student->find('all'));
