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?

Answer 1

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);

Answer 2

You can do like this

 $data["ids"] = $this->userdata_model->desc($id);
 $this->load->view('category/description', $data);

in your view you can access the variable using

$ids

Answer 3

$data is an array, contains all information, which you want show on view page.

In controller:

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

In view:

<div><?php echo $description; ?></div>

Answer 4

Because you call your View before call model, remove that row, and almost be good

$this->load->helper(array('form', 'url'));
$this->load->library('session');
$this->load->model('your model');
$data['Posts'] = $this->YourModel->ModelMethod();
$this->load->view('Your view', $data);

In your view foreach like this

<?php foreach($Posts as $item): ?>
  <?= item['id']   ;?> Or if you have STD Class <?= item->id   ;?>
<?php endforeach; ?>
