php - Unable to insert data -


i newbee codeigniter , php. trying insert data using form , display on same view page using mvc pattern given codeigniter. view is: 

<html> <head>     <title>my form</title> </head> <body>   <? echo form_open('books/input'); ?>   <? echo $id; ?>:   <? echo form_input('id'); ?>  </br>  <? echo $title; ?>:   <? echo form_input('title'); ?>  </br>  <? echo $body; ?>:   <? echo form_input('body'); ?>  </br>    <? echo form_submit('mysubmit','submit!');  ?>  <? echo form_close(); ?>  </body> </html>

and controller is: 

<? class books extends controller{      function books(){          parent::controller();     }      function main(){          $this->load->model('books_model');         $data = $this->books_model->general();         //$this->load->view('books_main',$data);     }      function input(){          $this->load->helper('form');            $this->load->model('books_model');          $data = $this->books_model->general();         $this->load->view('books_input',$data);        }  } ?>

and model returning data entered user as:

<? class books_model extends model{      function books_model(){         $this->load->helper('url');                    }      function general(){          $data['id']      = 'id';         $data['title']      = 'title';         $data['body']     = 'body';          return $data;        } } ?>

but when try access form, shows me error quoting:

    load->model('books_model'); $data = $this->books_model->general();  }  function input(){ $this->load->helper('form'); $this->load->model('books_model'); $data = $this->books_model->general();  $this->load->view('books_input',$data); } } ?>      404 page not found

though accessing same url: localhost/codeigniter/index.php/books/input

how can access form , insert data successfully?

every class name should start capital letter 

class books_model extends model

and type 

$this->load->model('books_model');

this issue getting "404 page not found".

read basic things have follow guide http://ellislab.com/codeigniter/user-guide/general/models.html
