how to send loop data to view - El Forum - 05-08-2014

Querying a database to return data in a loop to a view. How can I send the data to the view?

my function inside a model code is:

Code:
$query = $this->db->get('item');

  if($query->num_rows() > 0 )

  {

   foreach($query->result() as $row)

   {

      $data[] = $row;

   }

    return $data;

  }

I thought I could just use this to send it to the view:

Code:
$this->data['itemName'] = $data['ItemName'];

$this->load->view('items', $this->data);

error message I get is:

Code:
Undefined variable: data

if $data is being returned howcome data is undefined??

Thanks

Have you set

Code:
public $data = array();

at the beginning of the class?

You don't need $data variable in your view file, but output $itemName there:

Code:
var_dump($itemName);exit;

If not helping, instead these lines:
[quote author="jcjc" date="1399560525"]

Code:
$this->data['itemName'] = $data['ItemName'];

$this->load->view('items', $this->data);

[/quote]
output what you have got from model:

Code:
var_dump($this->model_name->model_method());exit; // this should be object or array of model data

Have you made relations between controller and model?
It is not seen in provided code.

When I try var_dump($itemName);exit; I get NULL.

When I try var_dump($this->model_name->model_method());exit; I get the results in the array. So the model works and returns the data to the controller - How can I pass this to the view?

You solved it than, almost.

Code:
$this->data = $this->model_name->model_method();

$this->load->view('items', $this->data);

Than you approach by keys of associative array you've already got (I.e. $nameItem if 'nameItem' is key of value in array).

Sorry, I don't understand well.
Can you write out here what array looks like and also what are you intending to use from it?

In my view I currently have:

Code:
&lt;?php foreach ($product as $item){ ?&gt;

              &lt;?php var_dump($item); ?&gt;

              &lt;?php echo $item['ProductName']; ?&gt;

              &lt;?php } ?&gt;

I get the following error:

Fatal error: Cannot use object of type stdClass as array

found the issue Smile

should have been:

Code:
&lt;?php echo $item->ProductName; ?&gt;

Thanks for your help Smile
