Hi guys I have this code and I am not sure what I am doing wrong, data is being defined as far as I can see, these are the errors I am getting:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: data
Filename: models/site_model.php
Line Number: 14
A PHP Error was encountered

You must use the "set" method to update an entry.
Filename: /Applications/XAMPP/xamppfiles/htdocs/BLOCK/models/site_model.php
Line Number: 14
controller:
<?php
class Site extends CI_Controller {
function index(){
$this->load->view('option_view');
}
function create(){
$data = array(
'subject' => $this->input->post('subject'),
'body' => $this->input->post('body')
);
$this->Site_model->add_record($data);
$this->index();
}
}
?>
model:
<?php
class Site_model extends CI_Model {
function get_records()
{
$query = $this->db->get('items');
return $query->result();
}
function add_record()
{
$this->db->insert('items', $data);
$return;
}
function update_record()
{
$this->db->where('id', 1);
$this->db->update('items', $data);
}
function delete_record()
{
$this->db->where('id', $this->url->segment(3));
$this->db->delete('items');
}
}
?>
and the view:

<input type="text" name="body" id="body">

<input type="submit" value="Submit">

What do you guys reckon?
Much appreciated
