Codeigniter Set variable

Question

I have a controller named categories in which I have

function description($id=null) {
    $this->load->helper(array('form', 'url'));
    $this->load->library('session');
    $this->load->view('category/description');
    $this->load->model('userdata_model');
    $data = $this->userdata_model->desc($id);
    $this->load->view('category/description', $data);
}

Now when I do print_r($data); it gives me the following result

Array
(
    [0] => stdClass Object
        (
            [id] => 4481
            [title] => Dvd Recorder Post
            [image_name] => 
            [image_name_work] => 
            [video_name] => 
            [work_type] => tape-recrder
            [description] => Test first..
            [agency] => 
            [services] => 
            [photographer] => 
            [company] => 
            [director] => 
            [dop] => 
            [userid] => 
            [display_order] => 99999
            [latest_work] => No
            [status] => Active
            [post_adddate] => 2012-03-26 10:14:07
            [date] => 2012-03-26 10:14:07
            [sub_cat] => dvd-reorder
            [views] => 75
            [url] => Dvd-recorder-post
            [post_cache] => 
            [post_cat_id] => 0
            [post_link] => 
            [post_pubdate] => 
            [post_seo_url] => 
            [post_status] => 0
            [post_type] => 0
        )

)

Now when I try to access $data in description.php in the view page it gives me following error

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: data

Filename: category/description.php

Line Number: 2

Anybody has an idea why?

CodeIgniter uses extract to generate the variables in the view page. So, you'll have to pass in an associative array as the second argument of the $this->load->view() call. In this case, if you want the variable to be named data, you'll have to pass in an array with the element key being data and the value being the data you retrieved from the model.

$data = array('data' => $this->userdata_model->desc($id));
$this->load->view('category/description', $data);
